Processibility of Fine-Grained Magnetite–Apatite Ore Mill Tailings at Kovdor Deposit
Abstract
The article presents the laboratory-scale studies on processibility of fine-grained old tailings at Kovdor GOK. Effect of collecting agents represented by fat tall oil acids (FTOA) is investigated. The froth flotation tests show high selectivity of agent Berol-2015 relative to apatite. From the lab-scale tests, it is found that with collector FTOA, the P2O5 content of concentrate is not higher than 24.4% despite a high degree of desliming of flotation feed (\(\sim70.0\)%). With collector Berol-2015, the concentrate content of P2O5 reaches 35.0–37.7% without preliminary desliming.
