Chromite Ore Beneficiation Solution (Gravity + Magnetic Separation)

Chromite Ore Beneficiation Solution-Chromite Gravity-Magnetic Separation Combined Beneficiation Process

This chromite beneficiation solution provides a high-efficiency combined process with "gravity-magnetic separation" as the core for the mineral characteristics of chromite (FeCr₂O₄). Through multi-stage classification and gradient sorting technology, combined with mature equipment and optimized configuration, it achieves high recovery and deep purification of chromite, taking into account the technical advancement and economic benefits.

I. Process Overview

Chromite has a large specific gravity and weak magnetism, which is suitable for the joint process of "gravity separation rough recovery + magnetic separation and purification". This chromite gravity-magnetic separation joint solution effectively improves Cr₂O₃ grade and Cr₂O₃ ratio through multi-stage crushing and screening, grading and re-election and medium-strength magnetic selection, which is characterized by smooth flow, strong adaptability and fast return on investment.

Second, chromite ore beneficiation process introduction

1. Crushing and screening system

   • After rough crushing by jawbreaker, the raw ore is graded into -5mm and +5mm by circular vibrating screen;

   • The +5mm material is finely crushed by roller crusher and then returned to the screen, forming a closed-circuit cycle to improve the crushing efficiency.

2. Gravity system

   • The -5mm material enters the ball mill for grinding, and the product after grinding is graded by high-frequency screen;

   • -2mm particle size is roughing and selecting by spiral chute;

   • The +5mm material is sorted by jigger to effectively recover medium and coarse chromite.

3. Magnetic separation and purification system

   • The re-selected concentrate enters the medium-strength magnetic separator to separate the residual iron minerals and improve the chromite-iron ratio;

   • The concentrate is dewatered by dewatering screen to obtain the final chromite concentrate product.

Third, chromite ore dressing equipment configuration

Fourth, the main technical and economic indicators

• Processing capacity: 15-100 t/h (can be customized)

• Grade of raw ore: Cr₂O₃ 25-35%

• Concentrate grade: Cr₂O₃ ≥ 45%, chromium-iron ratio ≥ 2.5

• Recovery rate: 3-5% higher than single process

• Equipment operation rate: ≥92%.
