copper molybdenum flotation

Copper-Molybdenum ores Danafloat

Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability. Further, because optimum moly flotation pH is at 7-8 while optimum copper selectivity is typically in the 9-11 pH range, use of a moly collector in bulk

Effects of aluminosilicate minerals on copper–molybdenum

01/07/2011· Porphyry copper deposits are the world’s main source of copper, molybdenum, and rhenium. They are also a significant source of gold, silver, tin, and a range of by-product metals (British geological survey, 2007). In many porphyry copper ores, various aluminosilicate minerals are present, such as kaolinite, chlorite, illite, and montmorillonite.

Flotation separation of copper–molybdenum sulfides using

01/11/2015· 1. Introduction. The selective separation of copper–molybdenum sulfide minerals by flotation mostly relies on the use of various depressants. Sodium hydrosulfide, sodium sulfide, cyanide and Noke’s reagent (thiophosphorus or thioarsenic compounds) are routinely used as the selective depressants of chalcopyrite (Bulatovic, 2007, Pearse, 2005, Prasad, 1992, Yin et al., 2010), the main copper

How To Increase Molybdenum Grade In A Flotation Plant

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
