Copper Ore Processing Methods

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

Extraction Of Copper | Mining, Concentration, Smelting

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. 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:

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.

How Underground Mining Works | HowStuffWorks

The least common method in hard-rock mining, block caving, is typically saved for low-grade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn.

ASSAYING WITH THE BLOWPIPE; LEAD, COPPER AND SILVER ORES

From the above it will be seen that the sulfide ores offer more difficulty than carbonate ores, although sulfide ores running as low as 7½ to 8 % have been assayed. If the ore is very impure, containing a great deal of copper, antimony or arsenic, as would be the case of an intimate mixture of galena with tetrahedrite, no dry method could be recommended as the results would be unsatisfactory.
