Mount Isa Copper Mine, Queensland, Australia

Ore processing. The copper concentrator was rebuilt in 1973, with rod and ball milling and three-stage flotation, to supply the roaster and conventional blister copper smelter on site. In 1981, Mount Isa commenced anode casting as well. In 1988-1989, two 6.4MW AG/SAG grinding mills replaced the rod and ball mills

Major Mines Projects Mount Isa Copper Mine

11/04/2020  Copper ore is mined in the X41 and Enterprise underground mines, where it is roughly crushed, then hoisted to the surface for processing. From here, it is fed through a series of ball mills that grind the rock into a fine dust. This dust is then mixed with water and reagents in the concentrator’s flotation circuit. The reagents help to ...

Mineral processing - Wikipedia

The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive.
