Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine ( – 1 % Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue. Therefore, in the first step the lumpy ore is crushed and milled into fine particles ...

Sunshine Mine process plant at Kellogg, Idaho (1980), but copper concentrate leaching was advanced to larger scales with the commissioning of the Bagdad, Arizona, concentrate leach plant (2003) and then the Morenci, Arizona, concentrate leach plant (2006). Copper concentrate leaching has been driven by two principal opportunities:

· 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. A gold deposit with a grade equal to 5 g/t (gram per ton) means that in one ton of the ore, we have 5 grams of gold. You can calculate the ore grade by dividing the valuable mass by the entire ore's ...

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 .
