Researching on double-reserve flotation reagents of phosphate mineral

摘要

Using of the process of "double-reverse flotation " to the semi-weathered ore resources from Yunnan Dianchi areas. The first section, it using the anionic collector to floating and excluding dolomite impurities;;The second section.it adopting cationic collector to floating the siliceous materialand and argillaceous gangue. In the "double reverse flotation technology", it mainly by adding a new phosphate inhibitor to enhance the efficiency on desilication and desmagnesiumtion;;also using a new desiliconization agent to improve the desilication efficiency and liquidity bubble.In the end,it can obtain qualified concentrate.
