ABSTRACT:
A process for the froth flotation separation of phosphate containing minerals by the use of a new collector agent is described. The new phosphate collector agent is prepared by mixing a fatty acid, tall oil pitch, an amine, and optionally sarcosine with fuel or furnace oil, and subsequently oxidizing the mixture by known methods. The new phosphate collector agent is added to the conditioned slurry of the ground and deslimed phosphate containing ore. The slurry is then subjected to froth flotastion in one or more stages to collect the phosphate concentrate in the froth. The phosphate collector agent is also effective in recovering phosphates from slime.
