Beneficiation tests were conducted on a high-talc complex copper-molybdenum ore. Two process schemes were explored, including pre-flotation for talc removal and direct talc depression. The results show that partial talc can be removed by pre-flotation with tap water, and pre-flotation with plant recycling water leads to high loss rates of copper and molybdenum in froth products, failing to separate easily floatable gangue minerals from copper-molybdenum minerals. By adopting a new depressant TCM-596 for direct talc depression in flotation with recycling water, a closed-circuit test produced a copper-molybdenum bulk concentrate with Cu recovery of 81.60%, Mo recovery of 63.95%, and MgO content of 2.43%. This indicates that talc is depressed and effectively separated from copper-molybdenum minerals, actualizing efficient enrichment of the high-talc copper-molybdenum ore.

对某高滑石型复杂铜钼矿进行了选矿试验研究,探索了预浮选脱除滑石与直接抑制滑石的工艺方案。结果表明,采用自来水预浮选时可以脱除大部分滑石,使用厂前回水预先浮选脱除滑石时,泡沫产品中铜和钼损失率高,无法实现易浮脉石矿物与铜钼矿物的分离;采用新型抑制剂TCM-596,在回水条件下进行直接抑制滑石的浮选,滑石得到有效抑制,闭路试验可获得Cu、Mo回收率分别为81.60%、63.95%的铜钼混合精矿,其中MgO含量为2.43%,实现了该高滑石型铜钼矿的高效富集。

对某高滑石型复杂铜钼矿进行了选矿试验研究,探索了预浮选脱除滑石与直接抑制滑石的工艺方案。结果表明,采用自来水预浮选时可以脱除大部分滑石,使用厂前回水预先浮选脱除滑石时,泡沫产品中铜和钼损失率高,无法实现易浮脉石矿物与铜钼矿物的分离;采用新型抑制剂TCM-596,在回水条件下进行直接抑制滑石的浮选,滑石得到有效抑制,闭路试验可获得Cu、Mo回收率分别为81.60%、63.95%的铜钼混合精矿,其中MgO含量为2.43%,实现了该高滑石型铜钼矿的高效富集。

Beneficiation tests were conducted on a high-talc complex copper-molybdenum ore. Two process schemes were explored, including pre-flotation for talc removal and direct talc depression. The results show that partial talc can be removed by pre-flotation with tap water, and pre-flotation with plant recycling water leads to high loss rates of copper and molybdenum in froth products, failing to separate easily floatable gangue minerals from copper-molybdenum minerals. By adopting a new depressant TCM-596 for direct talc depression in flotation with recycling water, a closed-circuit test produced a copper-molybdenum bulk concentrate with Cu recovery of 81.60%, Mo recovery of 63.95%, and MgO content of 2.43%. This indicates that talc is depressed and effectively separated from copper-molybdenum minerals, actualizing efficient enrichment of the high-talc copper-molybdenum ore.
