Abstract
A process for flocculating, in a liquid other than Bayer process streams, suspended solids comprised primarily of minerals other than iron oxide and tin oxide. The solids are contacted with a hydroxamated polymer. The amount of hydroxamated polymer is sufficient to increase the settling rate of the solids and to decrease the turbidity of the solids.
