Chromite is composed of chromium, iron, and oxygen, with variable amounts of magnesium, aluminum, and other elements. Chromite can occur in different forms within chromium ore deposits, including: Massive chromite: Chromite can form large, irregular masses or aggregates in the host rock, known as massive chromite. These masses may be composed ...
