针对铅锌矿多金属矿浮选试验参数优化研究

Study on Optimization of Flotation Test Parameters for Lead-Zinc Mine Polymetallic Ore

近几年,我国对有色金属的需求量较大,但有色金属行业还处于稳定发展时期,对一些金属的浮选工艺还不够完善。例如铅、锌金属虽然被大量运用到生活用品和工业生产中,但在铅锌浮选中,虽然锌的品位和回收率较高,铅的回收率并不高,一般在70%左右,这使很大一部分的有用资源被浪费。所以本文通过改变浮选试验参数的方式在保证锌品位和回收率的同时,提高铅的品位和回收率。

In recent years, China＇s demand for non-ferrous metals, but the non-ferrous metals industry is still in a stable period of development, some of the metal flotation process is not perfect. For example, lead and zinc metal are widely used in daily necessities and industrial production, but in lead and zinc flotation, although the zinc grade and recovery rate is high, lead recovery is not high, generally about 70% So that a large part of the useful resources are wasted. Therefore, this paper by changing the flotation test parameters in the way to ensure that the zinc grade and recovery rate, while improving the grade and recovery of lead.
