碳质铜页岩-石英混合物的聚（乙二醇）烷基醚浮选

摘要

研究不同聚(乙二醇)烷基醚(CnH2n+1O(C2H4O)m, CnEm))对碳质铜页岩−石英混合物浮选的影响。研究结果表明：所研究的聚(乙二醇)烷基醚(C4E1，C4E2，C4E3，C2E2，C6E2)都可以作为碳质铜页岩的浮选剂。C4E2和C2E2在碳质铜页岩和石英混合物的分离浮选过程中具有最佳的选出率。研究结果可为工业初选阶段分离碳质铜页岩中的有机碳提供参考。%The influence of different poly(ethylene glycol) alkyl ethers (CnH2n+1O(C2H4O)mH, CnEm) on flotation of carbonaceous copper shale mixed with quartz as a gangue mineral was investigated. The results show that all of the ethers C4E1, C4E2, C4E3, C2E2, C6E2 investigated can be used for the flotation of carbonaceous copper shale. The best selectivity of separation in the flotation of the carbonaceous copper shale and quartz mixture is obtained with the C4E2 and C2E2 ethers. The obtained data can be used for developing separation of organic carbon present in carbonaceous shale at a rougher flotation stage on an industrial scale.
