1. Introduction. Copper tailings are the byproduct of copper mining industry, and a kind of fine sand-like solid waste leftover from the copper extraction [].The emissions of copper tailings are quite high and up to 128 tons during the extraction process when 1 ton refined copper is produced [2,3].As Chinese economy develops, the demands for copper and copper allied products grow, and the ...
Copper Mineral Ore Grindingaluneth Mining. Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and c,copper mineral ore grinding.
A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.
