Organic Colloids

Organic colloids are used to protect certain mineral surfaces against the action of other flotation agents. As a result, all of these compounds might be considered as depressants which, when used in excess, can prevent al flotation with either anionic or cationic collectors. The principal application is on ores containing carbonaceous shales or clays. With such minerals, the organic colloids often reduce collector consumption and also improve dispersion and depression of the gangue slimes. Dextrin, tannin (quebracho), starch, and the lignin sulfonates are among the more important organic colloids.
