Recovery of apatite from flotation tailings. The ore is composed predominantly by apatite (84% in weight basis) plus silicates (16%). In order to treat the ore from beds 1-5, a suitable standard mineral processing circuit (composed of scrubbing, screening, attrition and desliming) started its operation in 2010, yielding 3.9 Mt/y of concentrate assaying 30% of …

The possibility of involving the apatite producing dead tails in the production cycle was investigated using a canned tailing dump that formed during the work of the apatite-nepheline processing factory (ANPF-1) in 1930–1940 and 1950–1969. According to preliminary estimations, the total volume of the field is approximately 40–50 million tons.
