Rocks containing copper compounds (such as copper carbonate) are called 'copper ore'. Copper is extracted from copper ore by a series of chemical, physical, and electrochemical processes. Ores can be classed as 'high grade' or 'low grade' depending on the percentage of copper compounds (e.g. copper carbonate) they contain.

which will help you to decide where to drill. Copper grade is the concentration of copper in the ore rock. To calculate the grade of copper for the sample, geologists use the equation: (amount of copper metal/amount of copper ore rock)*100 2. If a deposit area has 200lbs of copper in 10,000lbs of ore rock, what is the grade? 200/10000*100=2% 3.

Concentrates are made by crushing and then milling ore down to a particle size that permits copper to be released by flotation. Copper concentrations in concentrates from various places ranging from 24 percent to 36 percent. After that, the copper concentrates go through a final filtration and drying process to reduce the humidity to 8-9 percent.

What is Copper Concentrate? Although copper occurs naturally in a pure state, it's primarily mined from chalcopyrite, bornite, and malachite. Copper ore is extracted from the earth, then converted into copper concentrate, which is then roasted, smelted and converted into refined copper. The resultant metal is widely used for its high ...
