Abstract
Based on the mineral processing experimental research on mixed copper core containing molybdenum in Tibet and the features of the copper oxide,chelating collector B-135 is used and sulphide and oxide bulk flotation process is adopted,with the recovery rate of copper improved from 77% to 80%.At the same time,the process of copper molybdenum bulk flotation-inhibition of copper with flotation of molybdenum is adopted to obtain copper concentrate containing 20% copper and with 79% copper recovery rate,and molybdenum concentrate containing 48% molybdenum and with 87% molybdenum recovery rate.The research prompts the application of sulphide oxide bulk flotation in mineral processing of mixed copper ore containing molybdenum.
