Chrome & Manganese Beneficiation Plant

Robust gravity and magnetic dressing plants designed for high metallurgical grade chrome and manganese concentrate recovery.

1. Process Overview & Flowchart Explanation

The Chrome & Manganese Beneficiation Plant is designed for chromite (FeCr2O4) and pyrolusite/psilomelane (manganese oxide) deposits. Raw ore is crushed in a PE Series Jaw Crusher to produce calibrated -25 mm feed. Clay-rich ores are scrubbed and scalped across vibrating screens.

Coarse mineral fractions (2–25 mm) are treated using heavy-bed Mineral Jig Machines, producing lump metallurgical-grade chromite/manganese concentrate. Fine particles (<2 mm) are classified onto 6-S Shaking Tables for fine gravity concentration, followed by Wet Drum Magnetic Separators to remove tramp iron and recover magnetic manganese/chromite fines. All concentrates are dewatered on High Frequency Dewatering Screens.

2. Technical Advantages & Features

• High Lumpy & Fine Concentrate Recovery: Mineral jigs recover high-value coarse lump ore, while shaking tables capture fine mineral dust.
• Sawtooth Pulsation Water Savings: JT series jigs save 30-40% water consumption compared to traditional sine-wave jigs.
• Upgraded Cr2O3 and Mn Content: Upgrades low-grade 20-30% chromite/manganese up to 45-52% metallurgical grade.
• Simple Flowsheet & Low Capital Investment: Pure physical separation minimizes installation footprint and operating expenses.
