Mineralisation and Ore Type – Karara Mining

Mineralisation And Ore Type – Karara Mining

a high magnetic field allows separation of non-magnetic material to tailings. magnetic material remains as a concentrate and is transferred to the primary grinding plant. the primary grinding plant of four ball mills grinds the ore in slurry into fine particle sizes of <50 µm before further magnetic separation to produce a concentrated magnetite ore stream, with elevated iron (fe) grades of ~58%.,why the future is bright for nickel exploration - bnn bloomberg,the mineral awaruite is both highly magnetic and very dense, and is therefore amenable to concentration by mechanical processes including magnetic and gravity separation. this style of deposit is unique and presents considerable metallurgical and processing cost saving advantages.
