Experimental results carried out by Wilson and Ellis (1984) showed that the flotation techniques applied on a calcareous ore may be effective only if the phosphate can be highly liberated from the gangue materials in a relatively coarse size. In the case of the unaltered ores, complete liberation is achieved only with extremely fine grinding.
