Mar 02, 2021 For example, a copper ore grade of 1% means that in 100 tons of the ore, we have 1 ton of copper. If the copper ore contains 40 tons of calcite gangue, we can also say 40% of calcite in the ore. ... The valuable masse in the concentrate or the feed is calculated by multiplying the concentrate mass (or sample masse) by the grade as in the grade ...Get Price
The multimetal copper-zinc-lead ore is treated by integration of three complete banks in series, each one for copper, lead, and zinc to produce respective concentrates. In the case of complex ore metallurgy, bulk concentrate is produced containing all three primary metals and value-added elements like gold, silver, cadmium, cobalt, molybdenum ...

4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.
A process for the extraction of copper from a sulphide ore or concentrate comprises the steps of subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic solution containing halide and sulphate ions to obtain a resulting pressure oxidation slurry. The slurry is subjected to a liquid/solid separation step to obtain a resulting pressure oxidation filtrate ...
Dec 03, 2020 The copper is concentrated further by slurrying the ground ore with water and chemical reagents. In this process, air is blown through the mixture, and the copper floats to the top. The copper …

A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters. The concentrate may be smelted to produce blister copper for sale to a custom refinery, or the blister copper may be refined to cathode, which is then sold into the market.
