关于煤泥浮选药剂标准制定的探讨

    Discussion on the formulation of standards for coal slime flotation agents

    • 摘要: 浮选是目前分选细粒煤泥最有效的分选方法,而浮选药剂性能直接影响浮选效果。为合理使用浮选药剂,更好地满足浮选生产需求,文章阐述了煤泥浮选对浮选药剂的基本要求,指出了当前煤泥浮选药剂在使用过程中存在的一些问题,汇总了当前已颁布实施的煤用浮选药剂团体标准和行业标准中的技术条件,并对其进行了分析探讨。分析认为:浮选药剂标准的制定应注重于安全环保和职业健康,对于性价比等涉及经济效益的技术条件,因受煤质、浮选设备类型、药剂原材料品种及价格等多种因素影响,不宜作为浮选药剂的标准。文章还就现有浮选药剂标准中技术条件的调整和相关检测方法的优化提出了建议,可为煤泥浮选药剂标准制修定提供有益参考。

       

      Abstract: Flotation is the most effective method for separating fine coal slime, and the performance of flotation agents directly affects the efficiency. In order to use flotation agents reasonably and better meet production requirements, the article outlines the basic requirements for agents in coal slime flotation, points out problems existing in the current usage process, summarizes technical specifications from established group and industry standards for coal flotation agents, and provides an analytical discussion. The analysis concludes that formulating flotation agent standards should prioritize safety, environmental protection, and occupational health. Technical specifications related to economic factors such as cost-effectiveness are unsuitable as standardized criteria for flotation agents, due to variables such as coal quality, types of flotation equipment, variety and price of raw materials for agents. The study also provides advice on the adjustment of technical specifications of the existing flotation agent standards and optimization of relevant testing methods, which can provide useful references for the formulation and revision of coal slime flotation agent standards.
