The Production Process of South Africa Chromite Sand:
Step1: chrome ore raw material is processed by water washing.
Step2, drying raw materials to remove water;
Step3, drying raw materials into the vibrating screen, screening out the size of the customer needs;
Step4, the size of the sieve for magnetic separation, the purpose of iron and silicon removal. After magnetic separation, the chromium content reached more than 46% and the silicon content was less than 1%.
Step5: package the finished product.
