本文叙述了选矿厂经济学的两个要素.即增加收入和降低成本.在增加收入方面。首先要提高选矿厂的生产能力、回收率和精矿品位,而且还要注意副产品的回收和市场动态.在降低成本方面,要减少劳动力.采用大型设备和新技术新材料,降低动力、材料和药剂消耗.例举的新技术有炭浆法提取金、X—射线拣选金刚石、高梯度磁选、载流分析、粒度分析和计算机控制.文中还较详细地介绍了工艺过程控制的进展,破碎的发展,半自磨继续采用,浮选的新进展,浮选柱的复苏,重选的复兴,过滤工序的节约等有关内容,可供选矿工作者参考.
This article describes two elements of ore dressing plant economics: increasing revenue and reducing costs. First of all, to improve the concentrator’s production capacity, recovery and concentrate grade, but also pay attention to the recovery of by-products and market dynamics in reducing costs to reduce the labor force. With large equipment and new technology and new materials to reduce power, materials and The new technology is exemplified by the extraction of gold by plasma, X-ray diamond, high gradient magnetic separation, current-carrying analysis, particle size analysis and computer control.The paper also introduces the progress of process control in detail, The development of semi-autogenous abrasives, the new progress of flotation, the recovery of flotation column, the rejuvenation of re-election, the saving of filtration process and other related contents are available for beneficiation workers’ reference.
