To be more specific, let us take the example of a copper ore whose grade, or copper content, is only 1% by weight. Let us assume that the sole copper mineral species in this ore be chalcopyrite, which is one of the most popular copper minerals found in copper ores in our planet. The chemical formula of chalcopyrite is known to be CuFeS2. Calculating from the .

The copper extraction process begins at an open cut mine where Copper Ore is blasted and removed via Excavators and Tip Trucks. The ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor. When the crushed ore falls onto the conveyor it is transported to a Ball Mill to have its particle size reduced further. During, .

· When we concentrate ore by a single process or a flowsheet of processes, we need to calculate both grade and recovery to ensure the operation's success. Calculating one of them is not enough. First of all, using grade and recovery together means the valuable substance grade concentrating and its recovery into that concentrate. However, recovery calculation .

Key words: lowgrade ores; copper minerals; column leaching. 1. Introduction The highest quantities of copper, lead and zinc in the world are obtained by sulphide ore treatment. The reserves of highgrade ores from which the extraction of nonferrous, rare and noble metals is technologically and economically feasible are becoming scarcer year by year. At the same .

The ore is then ground finely before the copperbearing sulphide minerals are concentrated by a flotation process that separates the grains of ore mineral from the gangue (waste material). Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate can contain between 25 and 57% copper.

However, the impact of fluorine on copper sulphide ore processing was relatively unknown until the late1980s when the Ok Tedi copper mine was faced with the possibility of rejection of high fluorine bearing copper concentrate by Japanese smelters. As a result, Ok Tedi staff began studies aimed at identifying fluorine host mineralogy in the mine and developed control .

Metal ores are generally oxides, sulfides, silies (Table 1) or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust, or "noble" metals (not usually forming compounds) such as gold (Figure 1 ). The ores must be processed to extract the metals of interest from the waste rock and from the ...

In most cases, the thinlayer process was used where crushed ores (80% − in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.
