过去,浮选药剂的选择与优化过程都是相当不正规和过分简单化的,并且常以由一种矿物体系或从一家选矿厂中取得的个人经验为依据,扩大应用到另一种矿物体系中去摸索。没有一种公认的“标准”操作规程,并且这种不正规的选择过程又是充满着陷阱。另外,在这种选择方法中,矿物学性质的复杂性和易变性、以及在选矿厂中化学因素、物理因素和操作因素之间的相互影响总是被忽视了,而且选择的药剂只有着狭小的非优化的适用范围。因此,只从化学方面来解决一家选矿厂的要求并不可靠。从长远来看,这种方法的费用也是很高的,并且对我们的知识库几乎没有什么贡献。本文叙述了浮选体系的一种扩展的整体分析方法,并论述了用于浮选药剂选择和优化的一种合理的整体处理过程,以及采用贱金属硫化矿浮选体系作为实例,在选矿厂中可盈利的实施这一方案的情况。虽然初看起来,这个方法用于浮选体系中可能意味着是行不通的,但本文仍试图证明这种容易操作的整体处理方案是可以实施,并且也是很有必要的,以便研制出几种能符合选矿厂中选矿工艺要求的可靠的解决方法。
In the past, the selection and optimization of flotation reagents were rather informal and simplistic and were often extended to another mineral system based on personal experience gained from a mineral system or from a concentrator In to explore. There is no accepted “standard” operating procedure, and the informal process of selection is again full of pitfalls. In addition, the complexity and variability of mineralogical properties and the interactions between chemical, physical and operational factors in the mineral processing plant are always overlooked in this selection method, and only a small selection of agents The non-optimized scope of application. Therefore, it is not reliable to solve the requirements of a concentrator solely from a chemical standpoint. In the long run, the cost of this approach is also high and contributes little to our knowledge base. This article describes an extended overall analysis of the flotation system and discusses a rational overall process for the selection and optimization of flotation reagents and the use of base metal sulphide flotation systems as an example. In the profitable implementation of this program. Although it seems at first glance that this method may not work for flotation systems, this article still attempts to demonstrate that this easy-to-handle, holistic approach is feasible and necessary in order to develop several Able to meet the dressing plant beneficiation process requirements of a reliable solution.
