| titleOfInvention | The method for floating of copper sulfide zinc ore |
| abstract | The invention discloses a kind of method for floating of copper sulfide zinc ore, this method first selects copper to carry out bulk flotation to copper tailings again copper sulfide zinc ore crude, the dosing of copper tailings, stirring when bulk flotation, under the premise of obtaining stable foam layer, quick roughing flotation is carried out with the time no more than 1 minute, obtains the quick rougher concentration of zinc and zinc sulphur intergrowth mineral；Quick rougher concentration is directly entered that zinc is selected, and zinc sulphur intergrowth mineral carry out roughing at a slow speed, and obtained rougher concentration at a slow speed carries out entering zinc after ore grinding selected.The method for floating of the present invention sulphide ore monomer mineral portion good for floatability is after fast-flotation is enriched with, selected operation is directly entered without regrinding, realization can receive early receipts, the mineral of monomer, which are no longer pass through, to be regrinded, it can avoid crossing crushing phenomenon during regrinding, realize selective milling, the degree of dissociation of ore milling product improves.Therefore the grade and recovery rate of concentrate of concentrate can be improved with the method for the present invention. |
