  • The recovery of oxide copper minerals from a complex

      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
