Copper Ore Processing Methods 911 Metallurgist
2017-4-11 From an accessory to gravity methods, flotation very rapidly became a major process and finally, from 1923 to 1927, all but eliminated the gravity method in the treatment of low-grade sulfide copper ores. The rapid development of ball-mill grinding must also be attributed to the adoption of the flotation process, since it was the incentive for developing grinding methods which produced considerable copper minerals

Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe
The efficiency of copper ore comminution: A
This study analyzes the exergy efficiency of comminution using a laboratory sized dry ball mill and a copper mineral ore from central Chile. In this research, we develop a minimum work index from uniaxial compression tests results on the ore fitted to Morrell’s comminution energy equation using Hukki’s constant mineral parameter.
