A Study on Molecular Mechanics Analysis Flotation

Recently, the natural mineral resources became short. In the process of fluorite floatation and tailing recycling, the key point is to find out collectors which have good selectivity to fluorite and effective inhibitor of gangue. Most reagents primarily come from agricultural byproduct and some chemical byproduct. However, the tailing mineral is complex and difficult to collect, which brought
