AN INTRODUCTION TO COPPER EXTRACTION

Ball millThe ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor When the crushed ore falls onto the conveyor it is transported to a Ball Mill to have its particle size reduced further During ENG450 ENGINEERING INTERNSHIP MURDOCH UNIVERSITY AUSENCO SCHOOL OF ENGINEERING AND ENERGY ENG450 ENGINEERING INTERNSHIP MURDOCH

Grinding control strategy on the conventional milling

If the hardness of the ore increases the particle size in the mill discharge from ball mill 1 will increase With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase This will decrease the ratio and hence the control loop will add more water to keep the ratio constant However the amount of slurry reporting as fresh feed to the second milling circuit
