Pb Oxide Floatability & Selectivity VS Sulphidizer Usage

AM2 constantly requires the use of Na2S as its copper activator while CTC3 does not rely on Na2S. This dependence on Na2S causes AM2 to float more Pb in its concentrates as Na2S will also activate Pb Oxide minerals if present. For the average of all its tests, AM2 has recovered 62% of all Pb into the pre-float and Cu concentrate.19 - Flotation of Oxide Copper and Copper Cobalt,floatability of oxide copper minerals. Also, there is an appreciable difference in floatability between oxide minerals from carbonaceous and siliceous ores.The recovery of oxide copper minerals from a complex,,As a result of the mineral variations, the processing plant treats three distinct ore types, viz. oxide, sulphide and mixed. The objective of this study was to investigate the floatability of a complex Kansanshi mixed copper ore with a special focus on the sulphidisation process.
