| titleOfInvention | Use of tetraalkylammonium halides as flotation collectors |
| abstract | ABSTRACT OF THE DISCLOSURE A process for the recovery of copper minerals from oxidized ores by flotation employing sulphidization of the oxidized minerals followed by flotation employing a tetra-alkylammonium halide as collector. Preferably, a prior flotation step with a xanthate collector is employed, especially when the ore contains substantial amounts of unoxidized sulphide minerals. Using the preferred embodi-ment of the process it is possible to recover 10% more copper from an oxidized copper ore than is possible with sulphidization and xanthate flotation steps alone. |
