Improved leach recovery - IsaMill™ Advantages Isamill

While the IsaMill™ achieves efficient grinding to fine P80 it also has achieves a very sharp size distribution and a finer P98 sizing than alternative grinding technologies. Increasing activation energy. The rate of the leaching reaction for sulphide minerals is controlled by: diffusion of ions at the mineral : sulphate layer interface.

COMMERCIALISATION OF THE ALBION PROCESS Ph Fax

The first stage of the Albion Process is fine grinding of the concentrate using Xstrata’s IsaMillTM technology. Most sulphide minerals cannot be leached at acceptable rates at atmospheric pressure. The process of ultrafine grinding introduces a high degree of strain into the sulphide mineral lattice.

roasting vs ultrafine grinding of pyrite

Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation (Ellis and Gao, 2002).The gold sulfide concentrate is grind with an IsaMill to a P 80 of 10–12 μm.

IsaMill - Wikipedia

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, 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 as a more efficient means of coarse grinding. By the end of 2008, over 70% of the IsaMill’s installed capacity was for conventional regrinding or mainstream grinding ...

THE ALBION LEACH REACTORTM - Albion Process

The Albion Process is a combination of ultrafine grinding and oxidative leaching at atmospheric pressure. The feed to the Albion Process is a concentrate containing base or precious metals, and the Albion Process is used to oxidise the sulphide minerals in the concentrate and liberate these metals for recovery by conventional means.
