Recovery of phosphate ores in the modified three

2015-3-1  Flotation studies with phosphate ore were conducted to compare the CCC and 3PC. The studies were conducted on a laboratory column with an internal diameter of 2.54 cm, a height of 2.20 m, and an effective volume of 1.5 L, consisting of five adjustable glass modules. The conversion from the CCC to 3PC was done simply by replacing the upper part of the CCC by the inflection zone of the 3PC.

5 Types of Phosphate Froth Flotation Process

2020-4-23  The direct froth flotation process is to grind the phosphate ore until the minerals among the ore are dissociated after one stage grinding, suppress the gangue minerals by adding inhibitors, and then add the collector to enrich the phosphate minerals in the foam. This process must be combined with strong inhibitors to obtain best effect.
