直到不久以前,很多选矿厂通常对流程后部的浓缩和过滤给予很少重视。选矿厂的工程技术人员更倾向于把注意力多半集中在磨矿方面,努力提高选矿回收率和精矿品位。只有处理量大或矿石性质变化出现问题时暂时停止这方面的研究,而才考虑浓缩和过滤问题。但在过去几年里,随着能源价格上涨,金属价格普遍下降,目前普遍认识到选矿厂在脱水作业的成本节省是通常要考虑的问题。 Until recently, many concentrators generally paid little attention to the concentration and filtration of the back of the process. Concentrator’s engineering and technical personnel are more inclined to focus more on grinding, efforts to improve dressing recovery and concentrate grade. Only when there is a large amount of treatment or when there are problems with changes in the properties of the ore, the research in this area is temporarily stopped before concentrating and filtering the matter. However, in the past few years, with the general decline in the price of metals as a result of rising energy prices, it is generally recognized that the cost savings of concentrator plants in dehydration operations are a common consideration.
