Brief description of the flotation - foaming selective of phosphate ores and carbonate from ores finely divided or 13, sodium carbonate silicate - -

摘要

P the invention relates to a process of selective recovery of phosphate ores and carbonates from ores finely divided or 13, phosphates, carbonates - - silicates having a ratio of the phosphates, carbonates, the superior to 1. / p & & p & the method consists in adding an aqueous slurry of ores or 13, an anionic agent, to remove the collector of the surface of the ore particles, to subject the concentrated combines a flotation - foaming agent with a collector and a cationic agent depressant to the carbonate in order to recover the concentration of phosphates and the concentration of carbonates separately, or rendered inactive, the coating of the anionic agent at the surface of the minerals carbonates, a soumettrela sludge has a flotation - foaming of a recover separately a concentration of phosphates and a concentration of carbonates or a mixture of phosphates and a residue silicates, carbonates, - / p
