  • Sulfide Ores - an overview ScienceDirect Topics

    Nickel sulfide ores are processed by heap leaching in Sotkama, eastern Finland (Talvivaara, 2011). The process entails the following: (a) open-pit mining of 0.2% Ni, 0.5% Zn, 0.1% Cu, and 0.02% Co sulfide ore; (b) four-stage crushing; (c) rotary kiln agglomeration with sulfuric acid; (d) stacking the agglomerate in 8 m high heaps; (e)

  • Sulfide Ore - an overview ScienceDirect Topics

    A basic principle of many processes for extracting copper and nickel from sulfide ores is to overlay the molten ore or matte with a lime–silica–iron oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidizes and as a result, partitions to the slag phase, while some of the sulfur is carried off as sulfur dioxide.
