kyanite tailing sampling , CIS

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 apatitenepheline processing factory (ANPF1) in 1930–1940 and 1950–1969. According to preliminary estimations, the total volume of the field is approximately 40–50 million tons.
