Background Fosfértil was originally a state owned company, a subsidiary of Cia. Vale de Rio Doce and was named Valefertil.  Following government policies the company was privatized and shares were purchased by several small fertiliser blending companies, who formed the group Fertifos, to ensure their supply of intermediates.  The other fertiliser companies that are shareholders, besides Fertifos, are Bunge Fertlizantes and Fertibrás whilst nearly 25% is owned by individuals, banks and investment companies.

General The Uberaba–1 Complex, originally named Valefertil, was a pioneer in phosphate transport as it was the first factory world-wide to be fed with phosphate by a mineral pipeline.  This pipeline is over 125 km in length from the mine and beneficiation unit in Tapira, close to Araxá, to the chemical complex in Uberaba and has one intermediate pumping station. The phosphate slurry is pumped at about 60% solids and at the terminal it is thickened to 68% solids for feed to the phosphoric acid plant as a slurry.

News January 8, 2019 - Brazil’s Vale, the world’s largest iron ore and nickel miner, said in a securities filing on Tuesday that on January 8, 2018, it will conclude the sale of a fertilizer unit to US-based Mosaic Co. with adjustments. The changes will reduce the price tag of the sale by $1.35 billion.  The South American miner revealed that it wants to retain control of the TIPLAM port terminal, located in Brazil’s southeastern region and which was originally included in the deal. Even though Mosaic will still have the right to use the port facility, the plan change means that Vale will not receive the initially agreed $2.5 billion but it will get instead $1.15 billion plus 34.2 million shares in Mosaic, equivalent to 8.9 per cent of its total share capital.Back in December 2016 when the negotiation was announced, Mosaic had agreed to pay the highest amount for Vale’s stake in Peru’s Bayovar mine, the firm’s Kronau potash project in Canada and most of its phosphate assets in Brazil, including the terminal but excluding the nitrogen and phosphate assets in Cubatão, which will be bought by Norwegian chemical company Yara for $255 million.Despite the last-minute modification, Mosaic’s President and CEO, Joc O’Rourke, said in a press release that his company’s plans in Brazil have not changed. “We look forward to completing the transaction and working to realize the exceptional opportunity this acquisition presents,” he wrote.The transaction between Vale and the world’s No.1 producer of phosphate fertilizer is part of the former’s strategy to cut debt and focus on its core businesses.

- A fire disrupted operations at a Vale Fertilizantes plant in Brazil's southeastern state of Minas Gerais on Thursday, the company said.The fire occurred at a water cooling tower for a plant producing sulphuric acid in its Uberaba facility around noon and was under control within an hour, a spokesperson said in an emailled statement.No employees were hurt and the cause of the fire is under investigation, she said.Photos and video seen by Reuters showed billowing black smoke and fire covering a large section of the structure.Brazilian regulators approved Mosaic's purchase of Vale Fertilizantes in August in a deal that makes miner Vale the largest shareholder in the US-based firm.


January 27, 2010 - Vale SA agreed to buy Bunge Ltd.’s fertilizer assets in Brazil for $3.8 billion in cash as the South American nation, the world’s biggest producer of coffee, sugar and orange juice, seeks to cut its dependency on imports.   Vale will acquire 100 percent of Bunge Participacoes e Investimentos SA, which owns phosphate rock mines and assets in Brazil, and Bunge’s 42.3 percent stake in Brazilian fertilizer producer Fertilizantes Fosfatados SA, or Fosfertil, the Rio de Janeiro-based company said today in an e-mailed statement.   Vale, the world’s biggest iron-ore producer and second- largest nickel miner, is seeking to diversify from iron ore and boost investments in fertilizers throughout Latin America as Brazil aims to reach self-sufficiency in crop nutrients after prices surged. The company plans to become a global fertilizer supplier, Chief Financial Officer Fabio Barbosa said Aug. 4.  “Today’s acquisition adds value to Vale’s existing potash and phosphate mine assets, and is a positive diversification,” Gilberto Cardoso, a Rio de Janeiro-based analyst with Banif Securities, said in an interview. “Vale’s strategy is in line with the trend by the world’s big mining companies, including BHP Billiton and Rio Tinto, to invest in fertilizers.”  Vale sid that once the transaction gains approval from regulators, the company will start a mandatory offer to buy out the common shares held by minority shareholders of Fosfertil. Bunge said in a statement that it will use part of the net proceeds of $3.5 billion from the deal to reduce debt.

“This transaction is instrumental to the consolidation of Vale’s strategy on focusing on Brazil as the main market for its production of phosphates, given the potential of the acquired mines,” Vale Chief Executive Officer Roger Agnelli said in today’s statement.  Vale fell 85 cents, or 2 percent, to 41.75 reais as of 1:04 p.m. in Sao Paulo. Bunge, based in White Plains, New York, rose 36 cents to $62.38.  Fosfertil is Brazil’s biggest supplier of phosphate and nitrogen-based products for fertilizers production, currently supplying about 11.3 million tons a year of these materials, according to its Web site. The company, with phosphate rock mines in Goias and Minas Gerais states, has proven and probable reserves of 1.19 billion metric tons of phosphates, Vale said.  Vale is currently Brazil’s sole producer of potash, a raw material used in fertilizer production, at the Taquari-Vassouras mine in Sergipe state, where it produces 800,000 metric tons a year.

Brazil currently imports 91 percent of its potash needs, 49 percent of its phosphates needs and 75 percent of its nitrogen- based fertilizer raw materials, according to the national mining department’s fertilizer minerals coordinator, Joao Cesar de Freitas Pinheiro.  Vale plans to start in 2013 the 4.3 million-tons-a-year Rio Colorado potash mine in Argentina, bought last year from Rio Tinto Group. Other projects may boost the company’s output of potash to 12 million tons a year, Rubens Fernandes, head of Vale’s fertilizers business, said in an Dec. 14 interview. The company also aims to produce 9 million tons of phosphate rock.  Brazil’s potash consumption, now 6 million tons a year, is rising 5 percent a year, about double the world average, he said. Bunge said its share in Fosfertil, together with the other phosphate rock assets it’s selling to Vale, have an annual capacity of about 3 million tons.  Vale is also developing a phosphate rock mine at Bayovar, Peru, which is scheduled to start up this year.   Cash availability for the Bunge purchase is “no problem” for Vale, Banif’s Cardoso said, following its July 2008 share- sale, when it raised more than $12 billion.  “Vale’s got strong investment capability, it’s got a lot of cash reserves,” he said.
