Direct Flotation Hematite Silisicous Gangue

2020-4-27  Brief summary of the invention the invention relates to processes for direct froth flotation of the valuable niobiumbearing mineral pyrochlore nacanb 2 o 6 f from ores containing pyrochlore in admixture with gangue materials by direct froth flotation we mean that the flotation is carried out on the whole ore or on an ore residue which has been subjected to a nonflotative pretreatment.

direct flotation hematite silisicous gangue

1. Direct positive flotation is to inhibit gangue minerals and concentrate phosphate minerals into foam products. This flotation process is suitable for siliceous or calcium-silicate phosphate ore, the whole flotation process is to inhibit siliceous and carbonate minerals. Besides, this process has simple flow, flotation reagents and equipment.
