Abstract

Traces of a froth flotation reagent left in a product of a froth flotation process are removed by forming an aqueous suspension of the product, agitating the suspension, frothing it by aeration, and removing the froth. Lime may be added to the suspension to increase its pH value (preferably to at least 9) and thereby enhance the creation of froth. Reference is made to the treatment of comminuted rock containing traces of oleic acid, paraffin oil and pine oil.
