the the grinding size of copper ore for processing

Analysis of the Effects of Grind Size on Production

ore is concentrated into high grade copper concentrates. The process of conversion, in copper or any mineral concentration process is known as beneficiation, because it involves the aggregation of low concentrated valuable minerals between 0.9% and 5% into high grade between 15 and 50 % that can be .

3. Processing of Copper Ore

The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.

Mineral processing - Wikipedia

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
