DENSITY IN THE FLOTATION PROCESS WHITEPAPER
flotation process depends on the type of ore, due to different characteristics such as specific gravity and shape of the particles. For example, silicate minerals respond best to the flotation process at a feed density of approx. 20 to 30 % solids and the optimal coal pulp density varies in practice from 6
However, as flotation is a time dependent process, in the first moments of the flotation kinetics, it is usual to obtain high-grade concentrates close to the theoretical Li 2 O content of each mineral, because well-liberated particles of lepidolite or spodumene are the first to float.
Summary of Fluorite Ore Flotation Process
· 2 Flotation Processes of 4 types of associated fluorite. Just as is the case with almost ore processing and non-metal beneficiation, the concentrate fluorite is extracted by crushing, sieving, grinding, grading, flotation, filtration, drying, etc. How to realize the high-efficiency sorting of associated fluorite ore is a real problem in the ...
