国外某铁金钴矿选矿试验研究

Magnetic and gravity separation combined dressing experiment research on a iron-cobalt-gold ore abroad

摘要: 国外某铁矿富含金和钴,主要有价矿物为磁铁矿,其次是自然金和钴矿,根据矿石性质,综合对比了"磁-浮"与"磁-重"两种流程,最终,采用"磁-重"联合流程,在原矿含铁49.89 %,含钴0.047%,含金0.82 g/t的情况下,获得产率69.98%,铁品位67.63%,回收率93.81%的铁精矿;产率0.25%,钴品位10.22%,回收率56.51%,金品位197.57 g/t,回收率 57.21%的含金钴精矿。

Abstract: A iron-cobalt-gold mine abroad contains magnetite,natural gold and cobalt minerals,according to the ore properties,comprehensive compared magnetic and gravity separation combined & magnetic and flotation separation combined,at last,flotation and gravity separation combined process to deal with the raw ore which the grade of Fe,Co and Au are 49.89%,0.047% and 0.82g/t.As result,we obtain iron concentrate with yield is 69.98%,Fe grade is 67.63%,recovery is 93.81%.Gold cobalt concentrate with yield is 0.25%,Co and Au grade are 10.22% and 197.57g/t,recovery are 56.51% and 57.21%.
