This study presents research findings on the sulfidization and flotation processes of oxidized copper ore containing 0.86% total copper, 78% of which is in the form of oxidized minerals represented by malachite, azurite, and chrysocolla. Using a probabilistic-deterministic experimental design method, the influence of sulfidizer and collector consumption, as well as the agitation time of the pulp with the sulfidizer, was investigated. A mathematical process model was developed, and the optimal sulfidization and flotation processes conditions were determined, under which copper recovery in the flotation concentrate reached 85.1%, which is 3.2% higher than without the reagent.
