  • Sulfide Ore Processing « TCB Metals and Refining

    Instead of relying on autoclaves or roasting to prepare a sulfide ore for traditional leaching, our vibratory grinder on our circuit allows our leach to make contact with the precious metal encapsulated in the sulfide so leaching can occur. With the aggressive nature of our leach allowing us to process most ores in an hour, our process allows us to contain the amount of sulfur

  • Copper Extraction from Sulfide Ores Latest Contents

    This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides. The process is completed in about one year.

  • Processing of Nickel Laterite Ores on the Rise

    While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below. The method (s) chosen is dependent on the composition of the unique ore source.

  • Gold Recovery 101 Sepro Systems

    Sulfide-associated gold is often very fine in nature and difficult to separate from the sulfides. Refractory Gold A refractory gold ore can be defined as any ore that responds poorly to a conventional gravity- cyanidation process with examples often including copper porphyry, complex sulfides, arsenopyrite and lead-zinc associations.
