Pyroprocessing Sulfide Ores Provides Acid for Leaching
Contact SupplierThis "secondary enrichment" occurred when pyrite (iron sulfide) oxidized, dissolved in rainwater, and formed an acidic iron sulfate solution that dissolved the main copper-ore mineral, chalcopyrite (copper-iron sulfide). The dissolved copper was redeposited, principally as the mineral chalcocite (copper sulfide).
Contact SupplierSulfide Ore Processing. Home → Sulfide Ore Processing . Processing Sulfide Ores. Historically, miners have shipped their sulfide concentrates to overseas smelters that have little to no regulations or emissions controls.

Contact SupplierAlthough Minnesota has a long history of iron ore mining, sulfide mining for copper, nickel, and precious metals has never been attempted. Prices for some metals, including copper, reached historic highs in 2011, and some companies have sought to mine Minnesota's low-grade sulfide ores.
Contact SupplierNickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
Contact SupplierSulfide Ore any of several natural mineral formations consisting of metal sulfides. Metal selenides, tellurides, arsenides, and antimonides are also classified among the sulfide ores.
