Jun 28, 2017 Important strategic and commodity metals including, copper, zinc, lead, rhenium, and molybdenum are typically found in sulfide ores and less commonly in oxide-based ores, as is the case for aluminum. “What’s typically done is you burn those in air to remove the sulfur, but by doing that you make SO 2 [sulfur dioxide], and nobody is allowed

Why do we extract copper from low grade ores?

Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate. Slow process it can take years to extract 50% of the metal from a low grade ore.Energy is needed in the elctrolysis step. Then, the copper will be extracted from the leachate by electrolysis or scrap iron.

Copper Mining and Production Processes Explained

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Extraction of copper from copper pyrites (CuFeS2

Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S + O 2-----> SO 2 4AS + 3O 2----

Extraction Of Copper Mining, Concentration, Smelting

The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore: The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers.
