Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper. The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately

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 directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Copper concentrates. Used as raw materials in copper smelting, copper concentrates have a copper content of about 30% by weight. The remainder consists mostly of sulfur and iron. Copper concentrates are made mostly from sulfide ores. Ores extracted from overseas mines have a typical grade of about 1%. The ores are then "dressed" at the mine to increase the purity and produce concentrate. Most

Copper ore deposit geology. To a large extent, copper oxide and sulfides are naturally separated in nature: Copper orebodies are formed when geothermal solutions bring copper dissolved from deep underground near the surface and cool into rock. Copper is usually deposited as copper sulfides or copper metal. During millions of years the mineral deposit may be exposed to oxygen by air

Copper concentrate smelting is a large scale, intensive process consisting of four stages: sulphur in the sulphide minerals is "burntoff"; the metals are melted to form a "matte" and the waste material forms a "slag"; copper in the matte is electrorefined to copper metal; and the gold/silver is refined to doré. Facilities to do this are not currently available in Tanzania

Copper ores contain about % copper and are already processed into a concentrate in the mine. The concentrate is a finely milled, dark gray material containing about 30 % copper (Cu), 30 % iron (Fe) and 30 % sulfur (S). The concentrate also often contains small amounts of precious metals and a range of other elements, which we process in the smelters.

Beneficiation of copper ores produces concentrates consisting mostly of sulfide minerals, with small amounts of gangue oxides (Al 2 O 3, CaO, MgO, and SiO 2). Theoretically, this material could be directly reacted to produce metallic Cu by oxidizing the sulfides to elemental copper and ferrous oxide:
