Typical recovery figures are greater than 86% for alloy grades of 97% by mass. In addition to ferrochrome, the slag, which is largely a refractory spinel compound (i.e., MgAl 2 O 4), can be considered as a saleable byproduct. The leachate from the water leaching is evaporated to recover CaCl 2 which is then
The ferrochrome sector provides significant employment opportunities, supports local businesses, and contributes to export revenues. In 2023, Zimbabwe's exports of iron and steel reached US$390.19 million, marking a 67% increase since 2012. This highlights the sector's potential to drive economic growth and improve the balance of trade.
