| 摘 要： | 本文利用单矿物、人工混合矿和实际高冰镍矿石浮选分离试验，研究和分析了硫化钠（Ｎａ２Ｓ）对高冰镍中六方硫镍矿（Ｎｉ３Ｓ２）、辉铜矿（Ｃｕ２Ｓ）浮选行为的影响；利用捕收剂在矿物表面的吸附量测定及Ｎａ２Ｓ溶液中含Ｓ组分分布图探讨了Ｎａ２Ｓ对Ｎｉ３Ｓ２矿抑制机理。结果表明，在一定的用量范围内，Ｎａ２Ｓ对Ｎｉ３Ｓ２矿有较强的抑制作用，可实现Ｎｉ３Ｓ２与Ｃｕ２Ｓ矿的有效分离。

| Abstract: | The effects of sodium sulfide on flotation behavior of heazlewoodite and chalcocite in high nickel matte were investigated by flotation tests with pure minerals, artifiicial combinded minerals and high nickel matte. The depressing mechanism of sodium sulfide was examined by xanthate adsorption measurement on mineral surface. The results show that the heazlewoodite cah be strongly depressed by sodium sulfide at appropriate dosage, and the separation of heazlewooodite from chalcocite can be efficiently achieved. \ |
