Cassiterite Flotation - Tin Oxide

The nominal size range for cassiterite flotation is between 2 and 100 microns. The top size is variable depending upon the liberation of the cassiterite particles. Cassiterite grains coarser than 100 microns are difficult to float whilst grains finer than 2 microns give selectivity problems. Hence the feed for cassiterite flotation should be reduced to 95% minus 100 microns and then deslimed,The Practice Of Cassiterite Flotation In Bolivia,2.

It is well known that reverse flotation performance of iron oxides is affected by water quality. Since many potential variations among water sources recycling in a mineral processing plant bring unpredictable effects on the flotation system of iron oxides: disturbing ions/compounds, pH, hardness, residual reagents, etc. In this study, the recycled tailing water from a local plant,Advances in Centrifugal Gravity Concentration - Beyond Low,,Silver recovery from the flotation feed was the same at 66%, with a much lower mass yield, 12.4% as shown in Figure 4.
