Fluorite is the principal mineral of fluorine and usually coexists with quartz in deposits. The removal of fine quartz in fluorite concentrate is the main problem in fluorite flotation. In this study, the flotation tests on fluorite, quartz and a weight equivalent mixture (all less than 10 μm) using water glass (with different modulus) as depressants and sodium oleate as collector were conducted.

First off let us discuss why and how sanding occurs, because that does have an impact. Sanding can occur for many reasons, the two main and most common being; 1) poor classifiion ahead of flotation allowing oversized material to enter the cells, and 2) impeller wear leading to poor mixing in the cell.

A nickelcopper sulfide system usually coexists with serpentine in deposits. Low nickelcopper recovery and high content of serpentine in concentration adversely affects subsequent metallurgical processes. In this study, test data showed different rheological results at various densities. When the solid ratio of sulfide to serpentine was 1:1, lower pulp density (20 wt %) contributed to better ...
