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 Get price

sulfide mineral

Weathering may act to concentrate dispersed sulfides. Sulfide minerals are the source of various precious metals, most notably gold, silver, and platinum. They also are the ore minerals of most metals used by industry, as for example antimony, bismuth, copper, lead, nickel, and zinc. Get price

Why carbonate and sulphide Ores are usually converted into

Carbonate and Sulphide ores are usually converted into oxides because it is easier to obtain metals from the oxides by the process of Reduction. To get pure Metals from Sulphide Ores we usually use a process named as Roasting. Metallic Magnesium is obtained from its Carbonate ore by the process of Calcination. MgCO3 ---- MgO + CO2 Get price

Feb 15, 2020There is no one universal way of treating sulfide rich precious metal ores - in the mineral kingdom there are all sorts of complex minerals which contain, in addition to gold or silver, complex combinations of lead, zinc, copper, iron, nickel, manganese, palladium, mercury, antimony, arsenic and others. In addition to sulfur, one may also have ores with selenium, tellurium, and others. Get price

Copper Mining and Processing: Resources and Glossary

copper sulfide ore: A copper-containing ore that is typically a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals. Includes chalcocite and chalcopyrite. Typically processed using pyrometallurgy, although low-grade ores may sometimes use steps from the hydrometallurgy process. Get price

Sulfide Mining, Mining Methods, Techniques, Copper, Zinc

Sulfide Mining. Mining is the method of tacking materials from the earth to get valuable metal ores like copper, zinc, and lead, which are known as target minerals in mining terms. Metal ores like copper, zinc and lead are minute quantities contrasted to the whole composition of the earth. Get price

Smelting and Roasting Ores to recover gold, silver and

The product of melted sulfides is called a matte, and is highly corrosive liquid. Converting that molten sulfide matte to metal is called smelting. Small scale smelting can be done in a crucible – in fact that is what a fire assay is. When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix. Get price

Silver: A native element, mineral, alloy, and byproduct

Silver is a soft, white metal that usually occurs in nature in one of four forms: 1) as a native element; 2) as a primary constituent in silver minerals; 3) as a natural alloy with other metals; and, 4) as a trace to minor constituent in the ores of other metals. Most of the silver produced today is a product of the fourth type of occurrence. Get price

Roasting Definition in Chemistry

Sep 09, 2019Roasting Definition: Roasting is a process in metallurgy in which a sulfide ore is heated in air. The process may convert a metal sulfide to a metal oxide or to a free metal. Example: Roasting ZnS may yield ZnO; roasting HgS may yield free Hg metal. Get price

MASSIVE SULPHIDE DEPOSITS

Although it has been confirmed that sulfide immiscibility results from crustal contamination, grades of sulfide ores are also related to the nature of the parental magmas, the ratio between silicate magma and immiscible sulfide melt, the reaction between the sulfide melts and newly injected silicate magmas, and fractionation of the sulfide melt.
