flotation agents for phosphate rock

phosphate beneficiation in suriname

Chemical agents, which is frequently referred to as collectors, are used in conjunction with froth flotation to aid the beneficiation or concentration of phosphate content, or P 2 O 5 from phosphate rock. Phosphate rock is a natural rock consisting largely of calcium phosphate and used chiefly as a raw material for manufacture of phosphate
