Chrome Alluvial Ore Beneficiation Solution (Gravity + Magnetic Separation)

Chrome sand beneficiation solution, chrome sandore gravity-magnetic separation combined beneficiation process

I. Program Overview

Chrome sand ore (ferrochrome ore) is an important strategic mineral resource, which is widely used in metallurgy, refractory materials and chemical industry. This chromesandore beneficiation solution adopts the process of "ore washing - spiral chute gravity separation - magnetic separation and iron removal" to realize the high efficiency enrichment and purification of chromite ore, which has the advantages of simple process, energy saving and environmental protection, investment saving, and large processing capacity, and can significantly improve the economic benefits of beneficiation.

Process flow

1. Pre-treatment system

   • Raw ore is fed evenly through the silo

   • The rotary scrubber is used for preliminary screening and washing to remove clay and impurities.

   • Heavy-duty trommel screen for particle size grading to create conditions for sorting.

2. Gravity separation system

   • Primary spiral chute roughing: initial chromite enrichment

   • Secondary spiral chute sweeping: improve recovery and reduce tailings grade

   • Sorting particle size range: 0.1-5mm

3. Magnetic separation system

   • Adopting permanent magnet multi-cylinder magnetic separator for iron removal.

   • Multi-stage magnetic separation can be configured according to the iron content of the raw ore.

   • Field strength range: 1500-7000 gauss

4. Optional extended process

   • Jig separation: suitable for coarse chrome ore

   • Shaking table concentrating: to improve the grade of concentrate

   • Flotation process: for complex associated ores

Third, the core equipment configuration

Advantages

• ✅ High efficiency enrichment: double-stage spiral chute sorting, adapting to 0.1-5mm particle size range, high recovery rate.

• ✅ Energy saving and environmental protection: recycled water utilization rate >90%, no chemical additives, environmentally friendly.

• ✅ Low operating costs: spiral chute without power, the overall process is simple, low operating costs

• ✅ Large capacity: single line capacity up to 20-500t/h, daily capacity can be configured up to 10,000 tons.

• ✅ Flexible adaptation: the process can be adjusted according to the characteristics of the ore to meet different sorting needs.
