The proven ore reserves located above the Level +565 amount to 433,000 tonnes of ore grading between 30 and 34% chromium metal.
The mine's total reserves amount to 2 million tonnes of ore grading 40% chromium metal.
The refining processes for chromium metal have been thermodynamically defined by their spinel origins.
This chapter discusses the strengths, weaknesses, uses, limits, and possible improvements to alternative processes for producing chromium metal...
The proven ore reserves located above the Level +480 amount to 1,238,000 tonnes of ore grading between 24 and 28% chromium metal.
The proven ore reserves located below the Level +480 are currently not estimated or calculated but are expected to be grading over 30% chromium metal.
It is made from chromium ore and is part of the process for making chromium metal.
Louis Nicolas Vauquelin first isolated chromium metal from this mineral in 1797.
The 1 million tonnes of ore contains 480,000 tonnes of chromium metal.
It is found in places that make chromium metal, which is why they need to be cleaned up when they close.
