Mount Isa Mines - Wikipedia
From 1987, ore from the Hilton mine was used to supplement the Mount Isa ore, and by 1992, the treatment rate of the No. 2 concentrator had reached five million t/y, with 30% coming from Hilton and 70% from the Isa mine. In 1991, two semi-autogenous grinding mills ("SAG mills") were installed in the copper concentrator.

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.
