2021-4-1  The copper oxide ore sample used for the experiments was obtained from the Katanga province, D.R. Congo. Commercial grade reagent, 98% H 2 SO 4 was used for the leaching tests. The sample was subjected to particle size distribution analysis which indicated that the ore sample had a P80 particle diameter of 62.23 µm.

Copper Ore an overview ScienceDirect Topics

From plant practice, treating oxide copper and copper cobalt ores, two basic flotation methods are practiced: (a) sulphidization flotation method, and (b) anionic flotation method. 19.5.1 Sulphidization flotation method. This method is the most commonly used in beneficiation if oxide copper-bearing ore.
