Sulphidation Of Copper Oxide Ores For Flotation

The recovery of oxide copper minerals from a complex ...

2017-3-1  The preferred method for the flotation of oxide and mixed copper ores is sulphidisation. The reagents are typically sodium sulphide (Na 2 S) and sodium hydrosulphide (NaHS). Slug sulphidisation, which uses a single slug dose, is generally not preferred because the difficulty in controlling the pulp potential leads to poor mineral recoveries ...

2019-1-1  The micro-flotation results show that combined use of NaBX+DDA yields better effect than using NaBX at pH 7-11 only, and the optimal molar ratio of NaBX to DDA is 2: 1. The actual ores flotation shows that when the dosage of NaBX+DDA is (100+54) g/t, the copper concentrate grade and recovery are 15.93% and 76.73%, respectively.

2016-6-8  The traditional method applied for the flotation of copper oxide or mixed ores is sulphidisation, which was first developed with industrial success on Pb–Zn oxide ores in Australia (Crozier, 1991). The method involves multistage addition of sodium sulphide (Na 2 S), sodium hydrogen sulphide (NaHS), or ammonium sulphide (NH 4) 2
