assayed in an ore such as copper lead zinc etc. The feed grade was 1.4 copper The grinding circuit consisted of a rod mill followed A crushing section is where the ore is crushed by primary secondary and tertiary crushers to a final product size of –12mm with an 80 passing. Following the crushing section there is a wet grinding section consisting of a rod mill and ball mill where the crushed ore is further reduced in size to facilitate flotation of the various minerals.

Copper Mining and Processing Processing of Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1 copper) and ends with sheets of 99.99 pure copper called cathodes which will ultimately be made into products for everyday use.The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different energy required to operate large grinding mills such as ball and rod mills AG and SAG mills 5 . The influence of feed size on mill performance naturally follows from the fact that a considerable part of the grinding media (especially in autogenous mills) derives from the feed ore. Any change in the

Bond Rod Mill Index Test JKTech

Measuring ore grindability in rod mills. The Bond Rod Mill Work Index is a measure of the resistance of the material to grinding in a rod mill. It can be used to determine the grinding power required for a given throughput of material under rod mill grinding conditions. It is a locked cycle test conducted in closed circuit with a laboratory For example assume that raw ore is a two component system comprised of a valued mineral and host rock having relative densities of 6.30 and 2.65 respectively.
