Mining and Extraction: Oxide Ores - processes for ...

The flowchart above shows how the smelting process of sulfide ores produces sulphur dioxide, which is converted to sulfuric acid. The chart below shows how acid is used to leach out copper ions creating lakes of blue copper sulfate solution from which copper is recovered in a solvent and then electrolytically refined in a process called solvent extraction and electrowinning (SX-EW). This chart ...

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. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace. The liquid left is a mixture of copper sulfides and iron ...

Sulphur Melting and Filtration - Sulphurnet

The typical Sulphurnet sulphur melting and filtration process starts in the solid sulphur handling section, where solid sulphur gets loaded on a conveyor belt and gets neutralised by adding lime. Using the conveyor belt the solid sulphur is transported to the liquid sulphur melting tank, where the sulphur is heated until it’s melting point to form liquid sulphur. Whereafter the Liquid ...

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

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.
