Mar 01, · The oxide ore has a much higher grade than the mixed and sulphide ores but contributes less to the resource (Broughton et al., 2002). 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
