Synthesis of Zirconite

Synthesis of Zirconite

Mineral processing methods need to be heavy, magnetic, floating, electricity and other methods used in combination. If there is no selective high specific agents, a single flotation method is difficult to obtain industrial requirements of the concentrate products.

(1) re-election method Zirconium is mostly present in ilmenite, and often associated with hematite, chromite and garnet and other heavy minerals, so enrichment of zircon in the initial stage often use re-election method, Such as the use of shaking the first heavy minerals and gangue (quartz, feldspar, biotite), etc., and then use other means of mineral processing and other heavy minerals separation.

(2) flotation method Flotation commonly used collector for fatty acids, such as oleic acid, sodium oleate; pulp regulator to soda-based, pH = 7 ~ 8; inhibitor for the sodium silicate; activator for the vulcanization Sodium and heavy metal salts such as zirconium chloride, ferric chloride, also useful with oxalic acid to adjust the pulp to acid, with amines or amine derivatives as a collector.

(3) electrification electrification method is the use of mineral conductivity differences will be ilmenite, hematite, chromite, tin, rutile and other conductive minerals and zircon, monazite, garnet, apatite, etc. Non - conductive mineral separation. Before the election should be pre-degreasing grade, drying and dosing treatment.

(4) magnetic selection of heavy minerals in the mineral minerals are ilmenite, hematite, chromite, garnet, biotite, monazite, etc .; zircon is non-magnetic minerals or weak magnetic minerals (some deposits Zircon is iron with weak magnetic). Magnetic separation method of dry and wet two. Dry magnetic separation of the selected materials will be heated and dried, graded and other pretreatment before sorting. The wet-type magnetic field magnetic separator separation of its wide particle size, the lower limit of the size of up to 20μm, so when the zirconium particle size fine when the use of wet magnetic separator is more appropriate.
