ADEQ Smelter Permit Hearing Tomorrow

September 20, 2017 - It is happening tomorrow night (Thursday September 21st ) in the Miami Town Hall beginning 6pm.  This is when the Arizona Department of Environmental Quality will be holding a public hearing on its plans to issue a Renewal Permit for the continued operations  of Freeport McMoRan’s copper smelter near Miami.  It was back in 2014 when Freeport announced it was planning a major smelter expansion project at its Miami operations which the company said would increase copper production and also comply with new tougher EPA standard.  The company went on to say upon completion of the project the copper concentrate throughput for the Miami smelter would increase by approximately 30 percent to a capacity of 900,000 tons per year from the current average during this period of time which was some 700,000 tons per year.  According to the Arizona Silver Belt  the expanded smelter capabilities  would comply with the new EPA ambient air quality standards for sulfur dioxide emissions.  In further details about the copper smelter expansion project here a major component of the expansion was to install a new smelting vessel which along with modifications to other facilities in the smelter was to allow for increased copper production.  The local press was also told much of the construction work would be related to emission control systems in order to  capture virtually all fugitive gases and particulate emissions. The expected result would be  the capture of over 99 percent of the sulfur dioxide and other emissions from the Miami operations.  The new smelting vessel was scheduled to be commissioned in the second quarter of this year ( 2017 ) with production ramping up shortly thereafter.  Up to several hundred construction workers were involved in the expansion. The company said it had plans to hire about 20 new employees to operate and maintain the new emission control systems and facilities.  To feed the expanded smelter here additional copper concentrate was to come primarily from Freeport’,s mines at Morenci, Arizona and Chino , New Mexico.  Concentrate would continue to be coming in from the company’s Serrita and Bagdad Arizona mines.  Interested persons who plan to go to the public hearing tomorrow night still have time to view the ADEQ’s Draft Renewal of the Smelter Permit and other documentation which are available for inspection at  the Miami Town Hall during regular business hours  at 500 Sullivan Street in the Town of Miami.  Or this paper work can be reviewed directly from the ADEQ web site.  Oral and written comments will be taken from the public by representatives of the  Arizona Department of Environmental Quality.  Grounds for comment are limited to whether the draft of the agency’s smelter permit renewal meets criteria for issuance spelled out in the state air pollution control laws or rules.

Southern Peru Copper Appoints Jacobs as EPC for No. 1 Acid Plant

August 29, 2017 - Jacobs Engineering Group was selected by Southern Peru Copper to provide engineering, procurement and construction (EPC) services for its No. 1 Acid Plant upgrade project.  SPCC operates one of the world’s largest copper smelting/refinery facilities in Ilo, Peru, which is located approximately 600 miles south of Lima.  Jacobs will perform modifications to the existing acid plant, decreasing its sulphur dioxide (SO2) emissions while increasing sulphuric acid production capacity through the use of Jacobs’ Chemetics sulphuric acid technology.  “Our successful relationship with Southern Peru Copper Corp. (SPCC) spans more than 20 years,” said Jacobs Mining & Minerals and Specialty Chemicals Senior Vice President and General Manager Andrew Berryman. “We will provide our innovative Chemetics acid plant technology for this project, complementing the two existing plants our teams previously executed at the site, to further reduce SO2 emissions.  ”In addition to the No. 1 Acid Plant project, Jacobs is performing a feasibility study for SPCC in Lima for its power distribution system that will enable the company to support future demand. www.e-mj.com

Ravensthorpe nickel mine to close due to low market prices, 270 jobs impacted

August 9, 2017 - Canadian mining giant First Quantum Minerals has announced it will mothball its Ravensthorpe nickel operations in WA's south-east from early next month because of low nickel prices.  The Toronto-based company employs about 270 people at the Ravensthorpe mine and the closure will hit the community hard only months after devastating floods ripped through the region.  First Quantum said it would cost about $10 million to enter care and maintenance, which should be in effect by early October.  The annual bill of maintaining the site is estimated at $5 million.  In a statement, First Quantum's chief executive Philip Pascall described the decision as "disappointing".  "Ravensthorpe is an excellent operation with an outstanding workforce and supportive community but the continuing depressed nickel market conditions, over some years, leaves us no option," he said.  "Over the next few weeks we will work closely with our employees and key contractors to mitigate the impact and manage carefully the staged shutdown of operations.  "We will be offering assistance to employees in seeking further employment opportunities."  However, there is some hope for the mine, with First Quantum saying it would continue to progress the permitting process at the Shoemaker Levy orebody, along with regular review of the market conditions for a potential restart of operations.  To restart operations, should favourable conditions prevail, is estimated at $10 million.  The closure comes just weeks after First Quantum posted back-to-back quarterly losses.  The company reported a $US18 million loss for the June quarter, following a $US29 million loss in the March quarter.The miner also revealed Ravensthorpe - at current metal prices - is making a loss of more than a dollar on every pound of nickel it produces.  Ravensthorpe produced 11,512 tonnes of nickel at an all-in sustaining cost of $US5.70 per pound for the six months to June 30.  Global miner BHP spent about $US3 billion building and commissioning the facility in late 2008, before the global financial crisis forced its closure only months later.  First Quantum bought the mine for $US340 million in 2010 and restarted operations in 2011.  There has long been speculation about the future of Ravensthorpe, one of only two nickel laterite mines operating in WA, alongside Glencore's Murrin Murrin mine near Laverton.  First Quantum produced 23,624 tonnes of nickel last year, most of which came from Ravensthorpe following the $US712 million sale of the Kevitsa mine in Finland.The State Government said it would seek to assist those who will be laid off, with Mines and Petroleum Minister Bill Johnston saying he had been directed to launch a taskforce to help find those workers employment elsewhere within the industry.  "The Government will see whether we can work with these displaced employees to see whether they can get positions in expansion projects in the gold and lithium sector," Mr. Johnston said.  He admitted other nickel mines in WA were "under pressure" as a result of tough market conditions but expressed confidence the futures of the largest of those are secure.  Mr. Johnston was hopeful the Ravensthorpe mine would operate again.  "They are hopeful the mine will come back into production within two or three years because they believe the nickel market will come back," he said.  Premier Mark McGowan said he had a "great deal of sympathy" for the impacted workers and said as much support as possible would be offered.

Truck overturns, spills 34 000ltrs of sulphuric acid


July 26, 2017 - A ZAMBIAN truck overturned near Cross Dete along the Bulawayo-Victoria Falls road on Monday, spilling 34 000 litres of deadly sulphuric acid. Police officer commanding Hwange district, Chief Superintendent Newton Mutomba confirmed the accident and said efforts were underway to detoxify the area.  He said the accident occurred on Monday afternoon at Gulalembila, about 35km from Cross Dete. The truck was heading towards Zambia.  “The accident happened on Monday when a Zambian truck driver lost control and veered off the road,” Mutomba said.  “The tank’s lid burst and contents poured out, contaminating the area.  “The Environmental Management Agency and Civil Protection Unit are on the ground monitoring the situation and doing awareness campaigns to ensure that people are safe.”  There were no serious injuries, police said. The truck is still on the side of the road, where it is lying on its side.  Witnesses claimed the driver was speeding, as he was racing with other trucks.
 
Peru to extend liquidation deadline for La Oroya smelter again

July 26, 2017 - Peru's nearly 100-year-old polymetallic smelter La Oroya failed to draw any offers on Wednesday in the last of six scheduled auctions, delivering a blow to President Pedro Pablo Kuczynski's plans to expand the Andean country's metals refining capacity.Kuczynski had extended the liquidation deadline for La Oroya a year ago and vowed to do his best to revive it. But no one tried to buy the smelter in auctioning that started in March, even after the government raised sulfur dioxide emission limits to reduce the cost of upgrades.La Oroya will be liquidated unless Kuczynski extends the deadline again, said Pablo Peschiera, director of consulting firm Dirige that has been tasked with finding a new operator.Dirige has asked Kuczynski for another year to try to find a buyer, Peschiera said, adding that investors are still concerned about potential liability for pollution in surrounding soils.The town of La Oroya next to the smelter was once named one of the 10 most polluted places in the world by the group the Blacksmith Institute. Hundreds of children in La Oroya have been found to have dangerous levels of lead in their blood.Earlier this month, the environment ministry asked for input from the public on possible changes to rules on polluted sites."That (proposed) norm is extensive and will require a study by us and by investors as well," said Peschiera. "There wasn't enough time to overcome" the obstacles.The failed bid to sell La Oroya sets back Kuczynski's goal of raising the value of Peru's mineral exports by refining more concentrates at home. Kuczynski has said he hoped to revive La Oroya while encouraging investors to build a new smelter near Peru's southern coast.Peru is the world's No.2 copper, zinc and silver producer.Doe Run Peru, controlled by New York billionaire Ira Rennert's Renco Group, was La Oroya's most recent owner, but it went bankrupt in 2009 without finishing mandatory upgrades. The smelter is now controlled by Doe Run's former creditors
 
Chemical spill at Savannah's BASF plant sends 2 to hospital with burns

June 16, 2017 - Two people are recovering from chemical burns after an early morning sulfuric acid spill at Savannah's BASF Chemical plant on President Street.   Firefighters say those workers were using a hose to transfer sulfuric acid from one tank to another and that the hose sprang a leak.Hazmat crews decontaminated those workers on-site before sending them to the hospital for treatment.  No word on their conditions right now but look for updates as we learn more.

Xingfa awards DuPont contract for a 3600 tpd sulfuric acid plant in China

When built, the SAR unit at ZPC’s petrochemical complex will achieve world-class environmental emissions, reliability and on-stream time.”
 

Peru to reevaluate environmental laws over La Oroya smelter

 

April 12, 2017 - Peru’s environment ministry has proposed modifying laws restricting sulfur dioxide emissions to attract buyers for a century-old poly-metallic smelter.  The Doe Run owned smelter and neighboring Cobriza copper mine priced together at $100 million have failed to find buyers at three auctions in a time of low commodity prices. Analysts say restrictive environmental regulations make the La Oroya assets unviable in an area cited as one of the most polluted in the world. The smelter requires upgrades costing over $700 million.  A new resolution proposes ten modifications including raising the sulfur dioxide limit from 20 to 250 micrograms per square foot, in line with regulations in Colombia, Chile and Mexico. The World Health Organization (WHO) guideline is 20 micrograms per cubic meter.  “The World Health Organization recommends the limit of 20 as a target value, as an ideal value, but it also establishes intermediate values. No country in the world has 20. This proposal is more in line with reality,” environment minister Marcos Alegre told Gestion.  Alegre added that the new standard will generate greater competitiveness in Peru’s economy and “also protects health.”  The La Oroya district in Peru’s highland Junin state, home to 1,600 La Oroya workers, will likely be abandoned if the smelter and mine operations fail. President Pedro Pablo Kuczynski has vowed to save the smelter while diversifying Peru’s mining sector from production to value-added services.  The request to ease environmental regulation comes from workers and potential investors suggesting that both are awaiting the regulation change while the government schedules more auctions before August. Current owner Doe Run went bankrupt after the 2008 global financial crisis.  The La Oroya district found infamy after TIME magazine ranked it on its list of “The World’s Most Polluted Places.” The health ministry revealed 99% of its children have over three times the safety level of lead in their blood. The toxic metal damages mental development and causes comas, convulsions and death.  According to a study by the WHO in Hong Kong where large-scale reductions in sulfur dioxide have been a success, decreasing child respiratory diseases and all-age mortalities.



DuPont to Supply MECS® Technology and Critical Equipment for Codelco's Two New Sulfuric Acid Plants

March 31, 2017 - MECS Inc., a wholly owned subsidiary of DuPont, has been selected to supply the sulfuric acid production technology for two new plants belonging to Corporación Nacional del Cobre de Chile (Codelco), the world's largest copper producer. The MECS technology will treat off-gas from the Chuquicamata Copper Smelter Complex in the Antofagasta region of northern Chile.  Longtime MECS partner, SNC-Lavalin, will provide detailed engineering, procurement and construction services for the new plants each of which is expected to produce 2048 t/d of market-grade sulfuric acid. These plants will replace existing facilities which have become environmentally obsolete.  "MECS technology for Chuquicamata will be designed and custom-built to address the site's specific needs, especially achieving world-class low emissions and high reliability," said Kirk Schall, executive vice president, MECS. "We are delighted that our best-in-class sulfuric acid production technology will help Codelco's Chuquicamata site realize its short- and long-term emissions targets while supporting the sustainable production of the Antofagasta region's most valuable resources.
