设计及制造连续操作的实验室规模的浮选回路和小型设备的目的,在于尽量减少花费很大的半工业试验并得到进行全面浮选研究的设备。在本研究中,使用小型浮选机,通过模拟选厂选铜回路,对Keretti矿的复合硫化矿石进行浮选试验。在试验的同时,对选厂原流程取样以作为参考。这样就能够确定小型回路与生产规模之间浮选时间的放大系数。在设计新浮选流程时,可通过小型浮选槽对不同的流程结构进行灵活的试验。本文讨论了基于工艺指标的浮选时间的选择以及粗精矿和扫选精矿单独精选。
The goal of designing and manufacturing laboratory-scale, pilot-scale flotation circuits and small equipment that operates continuously is to minimize the costs associated with semi-industrial tests and to obtain equipment for full flotation studies. In this study, a small flotation machine was used to conduct a flotation test of the composite sulphide ore from Keretti mine by simulating the copper pick-up circuit of the mill. At the same time of the test, the original process of the mill was sampled for reference. This will allow you to determine the magnification factor for the flotation time between the small circuit and the production scale. In the design of the new flotation process, different flotation cells can be flexibly tested on different process structures. This article discusses the selection of flotation time based on process specifications, as well as a selection of coarse concentrates and sweep concentrates.
