Our common ultra-fine grinding mills can process raw materials into powders with a fineness between 80 mesh and 325 mesh and users can adjust the fineness according to their own needs. Service Online Ultrafine Grinder Ultrafine Mill For Sale
The Albion Process™ was developed at Core's Albion facilities (previously owned by MIM/Xstrata) during the early 1990's, and is a combination of ultrafine grinding, and oxidative leaching at atmospheric pressure. It is a highly effective process for the treatment of a wide range of sulphide based metal and precious metal concentrates, for precious and base metal recovery.
1 General Albion Process Description 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
