Antimony Ore Flotation Plant
Turnkey mineral beneficiation and flotation plants engineered to upgrade low-grade antimony ores (1.5% - 15% Sb) into smelting-grade antimony concentrate with high recovery.
1. Process Overview & Flowchart Explanation
The Antimony Ore Flotation Plant is specially engineered for primary stibnite (Sb₂S₃) and mixed antimony-gold/antimony-lead complex ores. Run-of-mine ore is reduced in a PE Series Jaw Crusher and fine-crushed in cone crushers to -12 mm. The crushed ore is pulverized in a closed-circuit Mineral Processing Ball Mill with Spiral Classifiers or hydrocyclones to 80-85% passing 74 microns (-200 mesh), achieving thorough mineral liberation.
The finely ground pulp is conditioned with activators (lead nitrate or copper sulfate) and xanthate collectors. Flotation takes place across XCF-KYF Inflatable Flotation Machines and SF-XJ Self-Aeration Cells configured in roughing, scavenging, and multi-stage cleaning banks. Gangue minerals like quartz, calcite, and iron sulfides (pyrite/arsenopyrite) are selectively depressed. The resulting antimony froth is dewatered in High Efficiency Thickeners and filtered via Disc Vacuum Filters into exportable antimony concentrate cakes (55%–65% Sb with residual moisture under 10%).
2. Technical Advantages & Features
- High Metallurgical Recovery (88-94%): Staged differential flotation circuits prevent ultra-fine antimony sliming losses.
- Low Impurity Transfer: Advanced differential depression suppresses arsenic and lead minerals, maximizing commercial smelting value.
- Energy-Efficient Grinding & Flotation: Forward-curved flotation impellers lower electricity consumption per cubic meter of pulp.
- Direct Export Cargo Link: For clients requiring immediate export-ready ore rather than building processing lines, EG Mining supplies direct shipping certified Antimony Stibnite Lumps (63-65% Sb) ready for vessel loading.
