From Ore to Finished Product - Copper

All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.

Nonferrous Metals Manufacturing Effluent Guidelines ...

Primary metals manufacturers extract metals from ores and operate smelters, which heat ore mixtures to separate liquid metal and impurities. Secondary manufacturers process recycled or scrap metals. Extraction processes include chemical addition (e.g. limestone, coke, soda ash) and treatments (e.g ...

The purified water from the vacuum distillation system can also be returned to the process. The equipment normally used for these processes is a batch treatment system for high copper concentrations (greater than 1000 ppm), continuous precipitation if the copper concentrations are less than 1000 ppm and the volume is greater than 5000 gpd.

Ore deposits formed by oxidation and supergene enrichment

3) Supergene enrichment may add much where there was little. 4) Leaner parts of the vein may be made rich. 5) Unworkable protore may be enriched to the ore grade. E.g. many of the copper districts would not have come into existence except for the process of enrichment.

Copper slag is a by-product created during the copper smelting and refining process. Copper slag is a by-product obtained during the production of copper metal, which can be used as pozzolana in the production of cementing materials. Recycling copper slag to recover metals has been focused on copper recovery.

Effect of Pretreatment on Leaching Primary Copper Sulfide ...

The aim of this study was to improve the dissolution of copper sulfide ore composed mainly of chalcopyrite (1.21 wt %) and bornite (0.54 wt %) using a pretreatment before leaching. The effect of the pretreatment on copper sulfide dissolution was investigated using different types of leaching. Three sets of experimental tests were performed (flask, reactor and mini-column).

Copper - essentialchemicalindustry.org

Manufacture of copper. About 80% of the world's primary copper comes from ores in which copper is present as a sulfide mineral, for example, chalcopyrite (CuFeS 2) (the most abundant copper ore), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S). These ores contain typically only about 0.5-2% copper.

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Supergene (geology) - Wikipedia

In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering.The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.
