Sulfide Ore Processing « TCB Metals and Refining

For companies with platinum group sulfide ore with valuable base metals of nickel, cobalt, etcin their ores, TCB can remove the precious metals and companies can then send the processed tailings to the proper refiner. TCB allows company representatives to be present during processing at our facility.

Sulfide Ores - an overview ScienceDirect Topics

Sulfide Ores. Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation. From: Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals, 2011

2020-5-18  Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an ...

Copper Mining and Extraction Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. FeO (s) + SiO2(s)→ FeO.SiO2 (slag) This is very similar to the removal of impurities in the blast furnace. The liquid left is a ...
