System Overview

ZOOMJO Group will customize nickel ore processing solutions based on your ore type to maximize the recovery of nickel concentrate. We also provide laboratory beneficiation test. Common nickel ore processing methods: nickel flotation separation process and pyrometallurgy (RKEF).

Nickel ores are mainly divided into sulfide nickel ores and oxidized nickel ores, with significant differences in beneficiation methods. Through years of development, the beneficiation technology of Zoomjo Group features high efficiency, low energy consumption, high output, and economic rationality, with simple process flow, low equipment cost, and easy operation.

Sulfide Nickel Ore Beneficiation Process

Crushing and Grinding

Jaw crusher (primary crushing): Raw ore (200-500mm) → crushed to ≤100mm

Cone crusher (secondary crushing): ≤100mm → ≤30mm

Ball mill (fine grinding): ≤30mm → ground to -0.074mm (200 mesh) accounting for 60-80%

Key parameters: Grinding fineness (-200 mesh ratio), pulp concentration (60-75%)
Flotation (core process)

Bulk flotation (flotate all sulfide minerals first, then separate nickel concentrate)

Preferential flotation (directly float nickel minerals)
Concentration and Filtration

Thickener: Flotation concentrate (70-80% water) → concentrated to 40-50% water

Filter (pressure/vacuum filtration): → water content ≤15%

Drying (if necessary): → water content ≤8%

Oxidized Nickel Ore (Laterite Nickel Ore) Beneficiation Process

Crushing and Washing

Jaw crusher: Raw ore (large pieces) → ≤50mm

Ore washing (removing clay)

Key parameter: Washing efficiency (removing -0.1mm argillaceous materials)
Gravity separation (optional)

Spiral chute/shaking table: Recover coarse nickel minerals (e.g., nickel limonite)

Key parameters: Feed particle size (1-3mm), gravity separation recovery rate (50-70%)
Magnetic separation (optional)

Low-intensity magnetic separation: Recover nickel-iron ore (e.g., magnetite containing nickel)

High-intensity magnetic separation: Recover nickel in hematite and limonite
Smelting (main method)

Pyrometallurgy (RKEF): Ore → rotary kiln drying → electric furnace smelting → nickel-iron (Ni 10-30%)

Hydrometallurgy (HPAL): High-pressure acid leaching (H₂SO₄) → nickel-cobalt solution → extraction → electrowinning nickel
