Copper Floatation Process Appliion The process starts with crushed ore. A ball mill receives the crushed ore and reduces its particle size to the consistency of sand. Next, the ground ore from the mill often travels as a highsolid slurry to a cyclone. The cyclone separates fine particles from heavier particles, which return to the ball mill
Copper Ball Mill Processing. Prompt : Caesar is a famous mining equipment manufacturer wellknown both at home and abroad, major in producing stone crushing equipment, mineral separation equipment, limestone grinding equipment, etc. Ball mill used for copper ore processing in the Philippines Crusher.
seconds by ball mill. During this period of time, more than50% of material left the fraction. It means the mentioned time is more than enough. In this respect 15, 30, 45, and 60 seconds were selected as grinding times. After this step, a pulp with 60% solidof each fraction (equivalent to feed concentration of Miduk copper ball mills) was prepared.
Answer: Ball mill is an important necessary equipment in copper processing production line. Requirement: the copper ore needs to grind coarsely first. The coarse ore goes to mill again. Then it needs rough flotation for one time, scavenging flotation for twice and concentrating flotation for twi...
