2018-7-11 An effective flotation approach is proposed for improving the recovery of molybdenite fines from a finely-disseminated molybdenum ore. To maximize the flotation recovery of molybdenum, process mineralogy of raw ore, contrast tests, optimization of operation conditions and particle size analysis were systematically investigated. Process mineralogy suggests that in the raw ore, 61.63% of

Application of D-optimal design for optimizing copper

2015-11-11 Keywords: copper, molybdenum, flotation, chemical reagents, D-optimal, optimization Introduction Although it seems that porphyry copper deposits are relatively simple, the geology of porphyry copper ores is almost complex and varies significantly within the ore body. Many copper sulphide ore deposits occur with molybdenum, mainly related to pyrite
