Heavy minerals are presented both in placer material and original rock mine. Normally two or more kinds of heavy minerals intergrowth together, and due to this characteristic, the processing plant would require multi beneficiation methods. Based on the heavy minerals processing experience and necessary processing test, Prominer can supply complete processing plant combined with various processing technologies, such as gravity separation, magnetic separation, flotation, electric separation, etc., to recover all kinds of heavy minerals and separate them as independent concentrates.For rock type ore, the primary processing is crushing and grinding to a suitable size that the minerals are liberated from veins and then the liberated material goes for separation stage. For placer mine, normally it needs to be sieved first to take out all big size veins and then goes for separation. Also, after analyzing if the liberation size is fine, then grinding will also be required.
Rougher gravity concentration: To obtain mixed rougher heavy minerals concentrates by using spiral chutes Rougher middling gravity concentration: Also use spiral chutes to make higher grade heavy mineral concentrates Cleaner gravity separation: Recover Tin ore concentrates first LIMS magnetic separation: Recover magnetite ore from the rest heavy minerals HIMS separation: Recover garnet, hematite, ilmenite and chromite step by step by using different magnetic field intensity HV electrical conductor separation: Make mixed non conductor mineral zircon, monazite and xenotime and conductor mineral zircon and metallic mineral.
