Comparison of energy efficiency between ball mills and …
The IsaMill employs a product separator that retains the media while allowing fine product to exit the mill. Any coarse media or ore particles which enter the product separator region are centrifuged towards the shell. The rotor acts like a centrifugal pump, pumping liquid back to the feed end of the mill.
The Albion Process™ for Refractory Gold Applications
The IsaMill™ produces a sharp size distribution in open circuit, as the feed must pass through multiple distinct grinding zones in series before reaching the Product Separator. This plug fl ow action ensures no short circuiting, and effi ciently directs energy to the coarser feed particles. The Product Separator is a centrifugal

Accurate scale-up
For an SG of 3 (e.g. Copper), it's 15kg. For an SG of 3.5 (Copper, Lead, Zinc) it's 17.5kg. For an SG of 4 (Pyritic Gold) it's 20. And for an SG of 4.5 (Magnetite) you could expect 22.5kg. Initial testing uses an M4 IsaMill™ to accurately determine the relationship between specific power draw and product size – the 'signature plot'.
1 General Albion Process Description
The Albion ProcessTM oxidative leach circuit oxidises sulphide minerals to either elemental sulphur or sulphate. This process liberates significant heat, and the oxidative leach is allowed to operate at a temperature close to the boiling point of the slurry. Operating temperatures are in the range 93 – 98. oC.

IsaMill
The patented IsaMill is a transformation in grinding technology based on high intensity stirred milling. The IsaMill was developed for fine grained orebodies that needed a step change in processing efficiency to be economic. The IsaMill significantly reduces the energy requirement, and media and capital costs of fine grinding.
