1. Washing-classifying-desilting: In the quartz sand beneficiation process, the fine-grained grade with a particle size of less than 0.1 mm is usually called slime.For quartz sand with a large amount of clay and ore mud, as the particle size becomes finer, the grade of silica gradually decreases, while impurities such as iron and aluminum rise instead.
So sometimes it's also called the flotation copper ore beneficiation plant. Working principle of copper ore beneficiation plant. The working principle of the copper ore beneficiation plant is as follows: minerals with their own hydrophobic property formed in the effect with the flotation agent will gather on the gas-liquid surface or the ...
