摘要:
针对云南某难选氧化铅锌矿石性质复杂，铅氧化率高，锌回收价值低等特点，进行了铅矿物硫化-黄药法浮选、脂肪酸直接浮选工艺对比。结果表明：相较硫化-黄药法浮选铅精矿铅品位55.62 %、铅回收率75.45 %，脂肪酸直接浮选工艺整体选矿指标更佳，铅精矿铅品位50.38 %、铅回收率78.08 %；且脂肪酸直接浮选工艺具有添加药剂种类少、用量小、选矿成本低等优势，选矿药剂成本比硫化-黄药法浮选低36.64元/t。脂肪酸直接浮选工艺更适宜于处理该难选氧化铅锌矿石。

Abstract:
A refractory lead-zinc oxide ore from Yunnan has complicated properties characterized high lead oxidization rate and low zinc recovery value.Therefore,the vulcanization-xanthate flotation and direct flotation by using fatty acid were compared.The results show that compared to the vulcanization-xanthate flotation which obtains the lead concentrate with lead grade 55.62 % and lead recovery rate 75.45 %,the direct flotation by using fatty acid has better overall beneficiation index that the lead concentrate obtained has lead grade 50.38 % and lead recovery rate 78.08 %;besides,the direct flotation by using fatty acid need less additive kinds,smaller dosage and low cost,its reagent cost is 36.64 yuan/t lower than that of the vulcanization-xanthate flotation.So the direct flotation by using fatty acid is better for the treatment of the refractory lead-zinc oxide ore.
