CESL, a wholly owned subsidiary of Teck Cominco Metals, has developed a novel hydrometallurgical process for processing copper sulphide concentrates to metal. The basic concept of this process is to allow processing of concentrates on site at the mine, to …

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 mined is concentrated. The milling of copper ores as practiced in the larger ...

In a follow-up process, the copper and sulfur-molybdenum concentrate are separated. The copper concentrate is filtered and dried in rotary kilns and later sent to the concentrate smelter, where it is melted at high temperatures in an oxygen-enriched atmosphere in either flash furnace-type melting units or in holding-type converters.

Hydrometallurgical considerations in processing arsenic ...

Concentrate is first reground prior to leaching at 150°C and 14 bar pressure. Retention time in the leach vessel is in the range of 60 to 90 minutes to promote complete oxidation of the copper sulphide minerals and to maximize the extent of arsenic precipitation within the vessel.

How copper is made - material, used, processing, steps ...

6 The copper concentrate is fed into a furnace along with a silica material, called a flux. Most copper smelters utilize oxygen-enriched flash furnaces in which preheated, oxygen-enriched air is forced into the furnace to combust with fuel oil. The copper concentrate and flux melt, and collect in …

processing of the concentrates by pressure leaching techniques, which rely on high temperature oxidation processes to solubilize copper (and by-product cobalt) whilst rejecting the iron predominantly as a non-hydrated haematite residue. Total pressure oxidation of copper concentrates is a process option, which has been tested previously on a

First Chalcopyrite Copper Concentrate Leaching using ...

A very cheap retrofit was undertaken on the existing oxide leach circuit and then fed a predominantly chalcopyrite/bornite concentrate (28- 30% Cu). After a very short commissioning stage of around ~6 weeks, it achieved recoveries in excesses of 99% out of the leach vessels.

Economic of Copper Processing - SlideShare

Effective costs of Copper Processing As each tonne of ore produces 0.0051 t of copper inconcentrates, with a free market value of £ 5.00, so totalproduction costs of copper in concentrates : However, if the ore contains appreciable by-products, theeffective production costs are reduced. Assuming the concentrate contains 25 gpt of gold and 70gpt of silver, then The payment of gold, at LME price of £ 230/troy oz (1 …

Copper Concentrate - an overview | ScienceDirect Topics

The copper concentrate is also processed through an acid leach to recover much of the other 20% of the uranium. The pregnant liquor is then separated from the barren tailings and in the solvent extraction plant the uranium is removed using kerosene with an amine as a solvent. The solvent is then stripped, using an ammonium sulfate solution and injected gaseous ammonia. Ammonium diuranate is then precipitated …

The copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities. The copper matte created by the smelting furnace contains 58-60% …
