About chrome ore
Chrome ore is smelted into ferrochrome for stainless steel. Smaller quantities go into foundry sand, refractories and chemicals. South Africa is by far the largest producer.
The chromium to iron ratio matters as much as the Cr2O3 grade, because it sets the chromium content of the ferrochrome a smelter can make.
Frequently asked questions
What is UG2 concentrate?
Chrome concentrate recovered from the UG2 reef in South Africa, often as a by-product of platinum mining. It is typically around 42% Cr2O3.
Do you supply foundry and chemical grades?
Yes, on request. These need tighter limits on silica and sizing than metallurgical grades.
How is payment usually made?
By documentary letter of credit from a bank acceptable to the seller, with payment against shipping documents and the inspection certificate.
