Applications of Custofloat Collectors in Processing Phosphate Ores from Different Countries

摘要

Most phosphate resources need to be processed to recover phosphate by rejecting gangue impurities prior to its application. The impurities associated with phosphate include silicates, carbonates, iron and aluminum oxides, etc. Among the technologies for processing phosphate ores, flotation is the most important approach, and it is widely applied in phosphate industry. The success of flotation separation largely depends on the usage of chemical reagents to control the surface behavior of the minerals in the ore and aqueous chemistry in the system. Therefore, the development of reagents, particularly collectors, is the key for achieving satisfactory separation performance through flotation process. In recent years, Arr-Maz Custom Chemicals has made great efforts in developing flotation reagents for beneficiating phosphate ores of different origins worldwide. This paper describes some flotation reagents and flowsheets for processing phosphate ores from different countries, such as the United States, Canada, China, Brazil, Peru, etc.
