Currently, a significant amount of niobium is lost as slimes, which are removed prior to flotation due to their negative impact on the separation. This thesis is investigated the potential of recovery the lost niobium through flotation.flotation recovery of mineralmeta. Sodium Mercaptobenzothiazole NMBT is an effective collector in a slightly basic solution lower pH values as higher pH causes mineral coverage, thus reducing the recovery of valuable metal copper. Most of the copper was recovered at the pH of 8.Sodium isoamyl xanthate is a strong collector and is mainly used for the flotation of non-ferrous metal minerals that require strong harvesting and do not require selectivity. For example, it is a good collector for flotation of oxidized sulfide or copper oxide ore and lead oxide vulcanized by sodium sulfide or sodium hydrosulfide.

Usually sodium sulfide is the sulfidizing agent which yields the best performance in most flotation systems 5,6,7. Salum et al.decompose in acidic environment and hence, results lower flotation recovery. Through proper control of pulp pH, one sulphide can be selectively floated from other. As regards other reagents used in sulphide flotation, depressants like sodium cyanide, ZnSO4, sodium meta bi-sulphite are common.Dalian Shangfeng Flotation Reagents Co., Ltd As one of the leading flotation collectors, flotation frothers, flotation modifier reagents, pine oil, sodium amyl xanthate manufacturers and suppliers in China, we warmly welcome you to wholesale bulk chemical products in stock here from our factory.
