The following diagram illustrates a typical material flow:
Chrome ore in various sizes is typically charged into a submerged
AC Electric Arc Furnace and reductants (coke, coal and quartzite
) are added. The smelting process is energy intensive requiring
upt to 4,000 kWh per tonne material weight. Slag is separated
from the liquid ferrochrome and tapped into ladles for further
processing. Liquid ferrochrome is then poured into moulds and
after cooling crushed into sizes as required by the customers.
Crushed ferrochrome is railed to final customers or harbours
for shipment.
