Step 1: Raw material preparation: chromite ore, already crushed into powder in South Africa, undergoes water washing to screen particle size, eliminating impurities and mud.
Step 2: Drying step: the washed raw material is dried to remove moisture.
Step 3: Particle sizing: The dried material is then passed through a vibrating sieve to attain the desired particle size required by customers.
Step 4: Magnetic separation: Sieved particles undergo magnetic separation to remove iron and silicon. Post-separation, chromite content reaches above 46%, while silicon content remains below 1%.
Step 5: Packaging: the processed material is then packaged as finished products.
