2.1 Introduction. IsaMill Technology was first developed at Mt Isa in the mid 1990's when a major research program was undertaken by MIM as it was then known (now Xstrata) to enable fine grained ore bodies to be economically developed. The first installation of the technology was at the Hilton Concentrator in 1992.

The average flow rate achieved before re-cycle flow control was between 200 and 250 m3/h, the variability in flow rate during normal plant operation can result in drastic changes in feed flow rate to as low as 50 m3/h as displayed in Fig. 4. The modification to recycle flow control has proven to be significant during periods of low feed flow to ...

Mining. "Named after the prospector "father" of Cloncurry, 38km to the southwest, Ernest Henry is 160km from Mount Isa.". The open pit is to be mined in eight stages with a strip ratio of 5:1, extending to a 5km perimeter, 1.3km diameter and a final depth of 570m. Driltech rotary rigs drill 17m holes for blasts of up to 500,000t.

QUEENSLAND, Australia - Anglo-Swiss mining giant XSTRATA has made plans to increase the concentrate production from its Mount Isa lead-zinc mill by 60%. The two-part project will raise ore throughput to 8.0 million tonnes per year, making Mount Isa the world's third largest zinc mine by the second half of 2008.

Xstrata Technology directly supports and markets IsaMill technology through its head office in Brisbane, Australia, and it's subsidiary company in South Africa.

A year later, Xstrata mounted a successful takeover bid for MIM Holdings, the Australian owner of the Mount Isa polymetallic mine. Xstrata failed in its attempt to take over WMC Resources in 2005, before turning its sights on Falconbridge. ...

A laboratory procedure was developed to determine the potential recovery improvement of installing a regrind facility at LNO. The last step in formulating the process flow sheet and defining the process design criteria was to construct and operate a pilot plant, which incorporated four banks of flotation cells and an Xstrata M20 Isa Mill.

A numerical model based on the discrete element method (DEM) was developed to study flow of grinding media in IsaMill. The DEM model was first verified by comparing the simulated results of the flow patter, mixing pattern and power draw from those measured from a 1:1 scale lab mill. Then the flow properties were analysed in …

Shortly after its merger with Xstrata, Glencore reviewed operations, resulting in mining developments being halted and job losses. In 2013, Glencore decided to drop the second phase of a $47 million expansion feasibility study for its Mount Isa operation, which reportedly could have extended the life of the mine by up to 30 years.

From base metals and back – IsaMills and their advantages in African base metal operations 57. The eight chambers in series mean that short-circuiting of the mill feed to the discharge is virtually impossible. There is a very high probability of media-particle collision as a result of the high energy intensity and the eight chambers in series.
