Abstract

The Khovu-Aksy Ag–Bi–Cu–Ni–Co arsenide deposit discovered in 1947 was explored in detail by 1954. The Tuvakobalt Mining Complex mined veins cutting skarns in the Khovu-Aksy ore field and used hydrometallurgical process of ores to obtain bulk concentrate in accordance with the ammoniac–carbonate procedure in 1970–1991. During 20 years of operation, 12 000 tons of cobalt concentrate were produced; this concentrate was processed at the Ufaley plant to produce refined Co, Ni, Cu, and Ag. Huge adit dumps of barren material containing oxidized arsenides and sulfides were accumulated and more than 2 million cubic meters of hydrometallurgical wastes are dumped in six disposal pits on the industrial site. The retained cobalt reserves (more than 16 kt) and reserves in the disposal pits (more than 2.5 kt) are valuable critical minerals.

俄罗斯图瓦共和国 Khovu-Aksy 钴砷化物矿床：生产和更新加工问题的新视角

摘要

1947 年发现的 Khovu-Aksy Ag-Bi-Cu-Ni-Co 砷化物矿床到 1954 年进行了详细勘探。 Tuvakobalt Mining Complex 在 Khovu-Aksy 矿区开采了切割矽卡岩的矿脉，并利用矿石的湿法冶金工艺获得散装精矿根据 1970-1991 年的氨-碳酸盐程序。在 20 年的运营中，生产了 12 000 吨钴精矿；该精矿在 Ufaley 工厂进行加工，以生产精炼的 Co、Ni、Cu 和 Ag。堆积了大量含有氧化砷化物和硫化物的贫瘠材料的垃圾堆，超过 200 万立方米的湿法冶金废物被倾倒在工业场地的六个处理坑中。保留的钴储量（超过 16 kt）和处置坑中的储量（超过 2.5 kt）是有价值的关键矿物。
