Contractor	Chemetics/Davy	Kvaerner
Remarks	Original capacity: 568 MTPD Design included the ability to double plant capacity. 1998 plant expanded to double production. Cost: US$103 million ⁽¹⁾ No. 1 Plant operates at steady rate	Gas cleaning and acid plant plot area = 6900 m² The ISASMELT™ furnace replaced two reverberatory furnaces and a Teniente converter for treatment of 1,200,000 tpa of concentrate. Two rotary holding furnaces are used for separating matte and slag product from the ISASMELT™ furnace. A waste heat boiler and electrostatic precipitator are used to cool and clean the gas before passing it to a sulfuric acid plant. Peirce Smith converters are used for converting the matte to blister copper. No. 2 Plant capacity fluctuates with operation of IsaSmelt and PS Converters NOx Treatment System: Stripper

General	Smelter originally started in 1960. Smelting facilities consisted of two reverberatory furnaces and four P-S converters. Smelter expanded in 1976 with two additional reverberatory furnace and three P-S converters. One of the original reverberatory furnaces was taken out of service and demolished. Smelter expanded in 1995 with a Teniente converter. 1995 sulphur dioxide capture was 30%. After 2007 modernization and expansion sulphur dioxide capture was over 92%.
