flotation of cassiterite with modified fatty acids

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 ...

Tin values in the form of cassiterite (SnO.sub.2) are recovered from aqueous pulps of finely divided cassiterite-bearing ore, preconcentrate or concentrate by froth flotation. The ore pulps are deslimed thoroughly, partially or not at all. Slimes, gangue or waste minerals in the pulps are selectively depressed by use of a metal salt/silicate reagent combination.
