中文摘要: 硫化铜和辉钼矿可浮性比较接近是导致铜钼分离困难最主要的原因。本文从铜钼分离现状和新技术两个发面对其进行详细介绍。铜钼矿石一般采用混合浮选工艺,然后通过抑铜浮钼方式进行铜钼分离。但是传统黄铜矿抑制剂存在选择性差、用量大、环境污染严重等问题。针对目前铜钼分离存在的问题,国内外科研者提出一些新的分离工艺,包括氧化-浮选、电化学浮选、海水浮选、浮选柱浮选、选择性浸出、超导磁选技术等,这些技术具有明显优势,但目前仅局限于理论阶段,需要进一步完善。另外,高效低毒抑制剂的开发仍是目前铜钼分离焦点话题。

Abstract:The similar floatability of copper sulphide and molybdenite is the main reason for the difficulty in the flotation separation of copper and molybdenite. In this paper, the current status and new techniques of copper-molybdenum separation were introduced in detail. Copper-molybdenum ore is generally subjected to bulk flotation process, followed by copper-molybdenum separation through the depression of copper sulfide. However, conventional chalcopyrite depressants have the disadvantages of poor selectivity, large dosage and serious environmental pollution. In view of the disadvantages in current copper-molybdenum separation, researchers domestic and international have proposed some new techniques, such as oxidation-flotation, electrochemical flotation, seawater flotation, flotation column, selective leaching and superconducting magnetic separation. These techniques have obvious advantages, but they are just limited to the theoretical stage currently, which need to be further improved. In addition, the development of high-efficiency and low-toxic depressant is still the hot topic in copper-molybdenum separation.
