Chromium is not added directly to the steel but in the form of ferrochrome, as the latter has a lower melting point. Many minerals contain chromium, but chromite is the only mineral from which chromium is extracted . The global ferrochrome market was valued at USD 16.10 billion in 2022 and is projected to grow to USD 24.03 billion by 2030.
