ABSTRACT The IsaMill™ is challenging the way that plants are designed and operated. This paper challenges existing designs of concentrator flow sheets, particularly focusing on magnetite circuits. From what has started out as a small scale ultra fine grinding mill in the pharmaceutical and pigment industries, it has been redesigned and improved upon for mineral processing, and has been the mainstay of fine grinding applications for over 10 years.
Inert Grinding The operation of the IsaMill™ using sand or slag, or more often ceramic grinding media, has a big advantage over steel media in conventional grinding systems, as it greatly reduces the generation of ferric ions. These are detrimental to flotation and leaching circuits, as the ions form a coating on the mineral surface, which hinders the action of the flotation or leaching reagents, resulting in more reagents being used, and may also result in poor metallurgical performance. Metallurgical Plant Design and Operating Strategies (MetPlant 2008) 18 - 19 August 2008 Perth, WA 48 Maintenance The IsaMill™ has been designed to keep maintenance simple.
At this site there is a M4 IsaMill™ lab scale unit, as well as a small scale tower mill. Magnetite ore for the testwork was sourced from Ernest Henry Mine tailings (EHM). This mine is a copper mine in North West Queensland, with the host rock being a breccia, which is comprised of strongly altered and replaced felsic volcanic fragments in a matrix assemblage of predominantly magnetite, chalcopyrite and carbonate minerals. Post flotation, the majority of the chalcopyrite and some other sulfides have been separated from the gangue stream, leaving it rich in magnetite.
