| titleOfInvention | Method for efficiently recovering cassiterite from fine-grain dip-dyed type tin polymetallic ore |
| abstract | The invention discloses a method for efficiently recovering cassiterite from fine-grain dip-dyeing type tin polymetallic ores, which comprises the steps of carrying out open-circuit coarse grinding on raw ores by a rod mill, then carrying out flotation to remove sulfide minerals, carrying out classification treatment by a hydraulic classification box, selecting a proper classification process for each grain-size intermediate product according to the mineral property of the intermediate product, adding amylopectin into tin middlings (medium and fine grains), then carrying out regrinding and recleaning, and carrying out classification on tin fine mud by adopting a flocculation flotation-high-frequency table concentrator reselection combined process, wherein the regrinding and recleaning middlings of the coarse-size middlings and the tin middlings are sequentially returned to respective ore grinding operation, so that a large grinding-reselection cycle is formed, and finally qualified tin concentrate and tailings are produced. |
