[Tom Orrow]

The technology includes the following:

ore preparation processes (crushing, grinding, classification, desliming)

primary beneficiation using gravity, magnetic separation and flotation

refinement of crude concentrates using magnetic fractionation, electrical separation and flotation by means of selectively acting agents (Flon-2, Flon-8)

chemical enrichment of tantalum-niobium concentrates to remove impurities from it

flotation recovery of apatite from tailings of the gravity separation process.

The technology is capable of producing the following commercial products: tantalum-niobium or niobium concentrate, apatite concentrate, magnetite concentrate, mica concentrate and rare earth products.

The amount of ore that can be processed per annum may range from 50,000 tonnes to 1,000,000 tonnes, which enables the recovery of 10-50 tonnes of tantalum concentrate containing 5-30% of Ta205, or 10-50 thousand tonnes of niobium concentrate containing 30-40% of Nb205, as well as 100-200 thousand tonnes of apatite concentrate.
