TACKLING IMPURITIES IN COPPER CONCENTRATES

Concentrate “A” has the sulphides being mostly chalcopyrite and some pyrite and a higher gangue fraction. Concentrate “B” distributes its copper mostly between chalcopyrite and tennantite and has considerably more pyrite. The mercury mineralogy for the two concentrates

Copper Handbook - World Bank

8. Copper occurs in three different types of mineral-tions - sulfides, carbonates and silicates. Sulfides are by far the most important and silicates are the least important. Sulfides consist of copper, sulfur and iron. Since copper metal is more easily extracted from the carbenate and sulfide minerals,

more concentrated than the crustal average, whereas iron and aluminum need to be only three to ten times as concentrated. Thus, copper is indeed a localized zone in the earth's crust that contains copper-bearing minerals in unusual quantities. 8. Copper occurs in three different types of mineral-tions - sulfides, carbonates and silicates.

Copper Ore Processing Methods - 911 Metallurgist

11-04-2017  Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore ...

Melting of platinum group metal concentrates in South Africa

Dried concentrate is pneumatically transferred to the submerged arc furnaces where it is melted to produce an iron-nickel-copper-cobalt matte that acts as PGM collector. Depending on the ore type and the configuration of the concentrator plant, the concentrate is very fine (top size below 75 micron) and contains about 300 ppm PGM+Au. In
