| titleOfInvention | A method of producing zinc and lead concentrate from flotation waste |
| abstract | 1. Method for producing zinc and lead concentratenfrom flotation waste produced in a mechanical processnenrichment of sulphide zinc-lead oresnby grinding and preliminary gravitational enrichment,ngrinding, classification and flotation, characterized bynwith a coarse part of the residual flotation wastenin the outer periphery of the dumps it surrendersnregrinding process and double hydraulic classificationnto a grain size below 0.1 mm and then flotationnselectively or collectively sulfide andnthe oxidized Zn and Lb minerals obtained in these processesnsemi-finished products are subjected to the purifying reflotation processnseparately or together of the same kindnbyproducts of zinc lead ore flotation, up tonobtaining qualified zinc and lead concentrates,nwherein the ratio of the intermediate from the treatment of wastenpost-flotation is at most 1: 1 rationto a semi-finished product from ore processing. |
