Effects of aluminosilicate minerals on coppermolybdenum Porphyry copper deposits are the worlds 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.

A novel approach for preferential flotation recovery of There are several flow sheets (listed in Fig. 1a and b) used in the flotation recovery of copper and molybdenum from their porphyry sulfide ores. Fig. 1a is a typical flow sheet that consists of two stages (Raghavan and Hsu, 1984, Bulatovic, 2007, Liu et al., 2011). The first stage, commonly known as the copper circuit, produces a bulk copper sulfidemolybdenum sulfide concentrate.
