Jiaozuo Zhongxin Mesin Industri Berat Co., Ltd.
Review turnkey mineral processing and gold recovery plant installations engineered by Zhongxin Heavy. Detailed case studies cover gold CIP/CIL cyanidation lines, copper ore flotation circuits, iron ore magnetic separation, and gravity concentration systems—complete with process flowsheets, equipment configurations, and verified mineral recovery rates.
Zhongxin Heavy Industry designs turnkey sulfide copper ore beneficiation plants featuring high-efficiency crushing, ball mill grinding, froth flotation circuits, and concentrate dewatering. We deliver customized EPC solutions and optimized flotation reagent schemes for chalcopyrite, chalcocite, and bornite extraction globally.
Copper sulfide flotation takes advantage of the physicochemical surface property differences among mineral particles—specifically their natural surface hydrophobicity and wettability—to separate valuable copper minerals from barren gangue.
Sulfide copper minerals possess inherent hydrophobicity. By introducing targeted flotation reagents—including collectors, frothers, and pH modifiers—the hydrophobic nature of mineral surfaces is significantly enhanced. Copper mineral particles selectively attach to rising micro-bubbles in the flotation cells, forming a mineralized froth layer that ascends smoothly to the pulp surface for concentrate laundering and recovery.
Mineralogical Characteristics of Typical Sulfide Copper Ores
| Typical Sulfide Copper Mineral | Chemical Formula | Mineralogical & Crystal System Characteristics |
| Chalcopyrite | CuFeS2 | The most common primary copper sulfide mineral, featuring a brass-yellow color with a bright metallic luster. It crystallizes in the tetragonal crystal system, commonly forming tetrahedral or pseudotetrahedral crystal aggregates. |
| Chalcocite | Cu2S | Exhibits a lead-gray color with a metallic luster. It crystallizes in the orthorhombic crystal system, typically presenting short columnar or thick tabular morphology. Chalcocite serves as the predominant mineral in secondary supergene copper enrichment zones. |
| Bornite | Cu5FeS4 | Known as "peacock ore," it features a dark copper-red color with an iridescent purplish-blue tarnish and metallic luster. Belonging to the isometric crystal system, it forms cubic or octahedral crystals and typically coexists with chalcopyrite and chalcocite. |
Sulfide Copper Flotation Reagents & Operational Functions
| Reagent Category | Key Chemical Reagents Used | Operational Characteristics & Functions |
| Collectors | Xanthates (Potassium Ethyl Xanthate - PEX, Sodium Butyl Xanthate - SBX), Dithiophosphates (Butylammonium Dithiophosphate / Dithiophosphate 25). | Chemically adsorb onto copper mineral surfaces to enhance surface hydrophobicity, enabling strong attachment between copper particles and air bubbles. |
| Frothers | Pine Oil (Terpineol), Methyl Isobutyl Carbinol (MIBC). | Lower slurry surface tension to produce dense, uniform, and stable micro-bubbles, facilitating smooth upward transport of copper froth to the surface. |
| Modifiers / Conditioners | Lime Ca(OH)}2), Sodium Carbonate (Na2CO3). | Regulate pulp pH, disperse ultrafine gangue slime, modify mineral surface charges, and optimize the selective flotation environment for maximum copper recovery. |
