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.

科夫多矿藏细粒磁铁矿-铂铁矿磨矿尾矿的可加工性

摘要本文介绍了对科夫多尔采矿公司（Kovdor GOK）细粒度老尾矿可加工性的实验室规模研究。研究了以妥尔油酸（FTOA）为代表的捕集剂的效果。泡沫浮选试验表明，相对于磷灰石，捕收剂 Berol-2015 具有很高的选择性。实验室规模的试验发现，使用捕收剂 FTOA 时，尽管浮选给矿的脱泥程度很高（\(\sim70.0\)%），但精矿中的 P2O5 含量不高于 24.4%。使用捕收剂 Berol-2015 时，无需初步脱泥，精矿中的 P2O5 含量可达 35.0-37.7%。
