Copper ore is mined in our 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 our concentrator's flotation circuit. The reagents.
Ore mined is roughly crushed on site, then trucked to the Mount Isa mills for processing. First . mills. This dust is then mixed with water and reagents in our zinc-lead concentrator's flotation circuit. . Lead concentrate is mixed with high grade silica, line and copper slag, a by-product of our copper smelting operations.
Mount Isa Mines Limited ("MIM") operates the Mount Isa copper, lead, zinc and silver mines near Mount Isa, Queensland, Australia as part of the Glencore group of companies. For a brief period in 1980, MIM was Australia's largest company. It has pioneered several significant mining industry innovations, including the Isa.
The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited and Netzsch Feinmahltechnik ("Netzsch"), a German manufacturer of bead mills. The IsaMill is primarily known for its ultrafine grinding applications in the mining industry, but is also being used.

The single ball mill circuit was successfully implemented in January.
Concentrator. Figure 1: IsaMills in the Regrind Circuits at the Mount Isa Mines Lead/Zinc Concentrator. The IsaMill is a horizontal high speed stirred mill that operates with very high power intensities. (up to 350 kW/m .. Another feature of the new circuit is the use of inert lead granulation slag as grinding media in the IsaMill.

In 1991 the introduction of a Netzsch laboratory stirred mill to the Mount Isa site was a turning point in fine-grinding and ultrafine grinding. The ½ litre bench scale mill resembled a milk shake maker and used fine copper smelter slag as grinding media. Testwork on McArthur River ore started in 1991, and by January 1992,.
Nov 6, 2017 . Ore mined is roughly crushed on site, then trucked to the Mount Isa mills for processing. First, the ore is ground into a fine dust via a series of ball mills. This dust is then mixed with water and reagents in our zinc-lead concentrator's flotation circuit. The reagents help us to separate the valuable mineral.

Mount Isa Mines (Xstrata ) operates two separate mining and processing streams, copper and zinc-lead-silver. Mount Isa Mines' copper operations include two underground copper mines – Enterprise and X41, with ore mining capacity of 6.2mt per annum; a concentrator with 7mt per annum capacity; and a copper.
This review examines the broad reasons for different technical efficiencies for various types of size reduction devices. In particular, size reduction devices with confined bed breakage, with stirred mills of various rotational speeds and therefore various energy intensities, and other mills such as the Hicom Nutating Mill and the.

The following day we visited the Glencore copper concentrator and copper smelter. At the concentrator, it was exciting to see two SAG mills side by side as a separate comminution circuit is used to process the recycled slag from the smelter.

The commercial development of the Cell occurred indirectly as a result of problems being experienced in MIM's Mount Isa lead–zinc concentrator (sometimes referred to as a "mill" in the mining industry). MIM had been operating a lead–zinc concentrator at Mount Isa since 1931, although lead–zinc ore was substituted with.
