Evaluation of the Furnace Method for the .

The model of the furnace method predicted no Cr(VI) to have formed (by fuming of chromium). Some Cr(VI) may still form from raw materials being carried over with the off-gas and slag particles. However, this is expected to be much lower than that of the mixing method as the furnace is closed and the air ingress is therefore minimal.

Ferrochrome - Wikipedia

Ferrochrome, or Ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy between chromium and iron, generally containing 50% to 70% chromium by weight. Ferrochrome is produced by electric arc carbothermic reduction of chromite. Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large .

Release behaviour of chromium from .

Although chromium exists in the slag as highly immobile Cr (III) state, there is possibility of chromium release under different adverse conditions inter alia its conversion to highly leachable Cr (VI) state. While Cr (III) is an essential trace element in glucose synthesis, the Cr (VI) compounds are very toxic and highly leachable.
