Separation mechanism of malachite and dolomite using a novel depressant disodium glycerophosphate in copper oxide ore flotation

Key Points

• Effective separation occurred with disodium glycerophosphate as a selected depressant, enhancing copper oxide ore flotation.
• Testing indicated over 80% separation efficiency between malachite and dolomite in controlled flotation experiments.
• Assessment using a flotation method showed favorable results for disodium glycerophosphate in differentiating minerals.
• This novel approach may enable improved strategies for copper oxide ore processing and mineral separation.
