depositio of copper ore by magmetic concetration procces

Ore genesis - WikipediaLiquid immiscibility: sulfide ores containing copper, nickel, or platinum may form from this process. As a magma changes, parts of it may separate from the main body of magma. Two liquids that will not mix are called immiscible; oil and water are an example. In magmas, sulfides may separate and sink below the silicate-rich.depositio of copper ore by magmetic concetration procces,Sedimentary Mineral Deposits - 911 MetallurgistMar 18, 2017 .

The specific gravity varies between 4.6 and 4.8. Covellite is a characteristic mineral formed by weathering and leaching of copper sulfide minerals, and concentration in the zone of secondary supergene enrichment below the zone of oxidation. The total process raises the metal content to the level of 66.4% Cu in Covellite.

Tailings What are tailings? - Their nature and production

Introduction. Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never 100% efficient,.
