Procedure

By applying to the same ore the known process with depression of the phosphate by alumine sulphate and sodium-potassium tartrate, and flotation of the carbonates by sodium oleate, while using: 1760 g/t of 96% H2SO4 250 g/t of Al2 (SO4)3 -500 g/t of sodium-potassium tartrate 5000 g/t of sodium oleate, the following results (table VII) were obtained.
