The effect of grinding conditions on the flotation of a sulphide
The ROM copper ore sample was crushed in a roll crusher, in closed circuit with screening, to produce 100% passing 1 mm with minimal ultrafines production. Flotation is the main process of copper ore beneficiation. It requires fine particles with a size of 0.02–0.1 mm [ 10, 11, 12, 13 ].

Grinding is one of the most important technological processes used in many branches of industry. For example, in the construction industry, grinding is used to crush components of building materials; in metallurgy–for metal ores; in the chemical and pharmaceutical industries–for substrates and reaction products; in the food industry–for 1. Introduction. Wet milling in ball mills followed by flotation is the general practice employed in the beneficiation of copper sulphide ores in which the major minerals of commercial significance typically are chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS) and chalcocite (Cu 2 S).

Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is The processing technology of copper ore beneficiation plants includes flotation, microbial leaching, segregation, beneficiation, etc. Single sulfide ore is mostly processed by flotation, and copper ore processing equipment adopts the crushing-grinding-classification-flotation-concentration process to select single copper sulfide Copper Ore Beneficiation Processing Technology JXSC Mineral
