The Huangshaping Lead-Zinc Mine, a typical lead–zinc sulfide mine with a long service life, has accumulated a great deal of experiences in lead–zinc beneficiation over the past nearly six decades of production. Hereby, a comprehensive review of the Huangshaping Lead-Zinc Mine is therefore presented, covering the ore genesis, mineral composition and its dissemination relationships, and the flotation processes that were and are being used. Focally, a detailed summary of the trade-offs of the six flotation processes, bulk flotation process with two-stage grinding, partial (Pb-Zn) bulk flotation process with one stage grinding, bulk flotation process with one stage grinding, -flotability process, -flotability process with Zn preferential flotation for tailings, and preferential flotation, used at specific historical stages is highlighted. The objective of the current work is to provide a detailed and referable source for the beneficiation of lead–zinc sulfide ores by reviewing the production practices of the various processes used at the Huangshaping Lead-Zinc Mine, thereby providing valuable guidance and lessons for the future development of other mines sharing similar mineral characteristics with a view to achieving efficient recovery of lead–zinc resources.

铅锌浮选：黄沙坪铅锌矿近六十年创新回顾


黄沙坪铅锌矿是典型的长寿命铅锌硫化矿矿山，经过近六十年的生产，积累了大量的铅锌选矿经验。在此，对黄沙坪铅锌矿进行了全面的回顾，包括矿石成因、矿物成分及其分布关系以及过去和正在使用的浮选工艺。重点详细总结了六种浮选流程的权衡，两级磨矿的散装浮选流程，一级磨矿的部分（Pb-Zn）散装浮选流程，一级磨矿的散装浮选流程，-可浮性流程, - 强调了尾矿优先浮选锌的浮选工艺，以及在特定历史阶段使用的优先浮选。本工作的目的是通过回顾黄沙坪铅锌矿各工艺流程的生产实践，为铅锌硫化矿的选矿提供详细、可参考的资料，为今后的工作提供宝贵的指导和借鉴。开发具有相似矿产特征的其他矿山，实现铅锌资源的高效回收。
