Copper–molybdenum ores flotation in sea water

2013-11-1  Laboratory rougher flotation tests were conducted with two samples of Cu–Mo ores in fresh water and in sea water as a function of pH. In both cases Cu recoveries were slightly lower in sea water than in fresh water for a wide range of pH (pH 7–12). Flotation of molybdenite was however strongly depressed in sea water at pH higher than 9.5.

A process mineralogy approach to optimize molybdenite

2020-10-1  One of the challenges for the flotation of copper-molybdenum ores is the presence of copper sulphide minerals in molybdenum concentrate. Small grains of chalcopyrite (smaller than 50 μm), as well as pyrite, are the major impurities in the molybdenum concentrate. To a lesser extent, other copper sulphide minerals such as chalcocite and

Copper-Molybdenum ores Danafloat

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. 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.

Effects of aluminosilicate minerals on

2011-7-1  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.

Molybdenite flotation from copper/molybdenum

Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with traditional reagents the single-stage rougher flotation recovery of molybdenite

2021-8-11  The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then
