More DetailsY.E. Lee, in Encyclopedia of Materials: Science and Technology, 2001 (b) Ferrochrome–silicon Ferrochrome–silicon is another chromium ferroalloy directly produced from chromite ores by carbothermic reduction in submerged arc furnace. The chromium content ranges from 34 to 42%, that of silicon from 38 to 45%, and that of carbon from 0.05 to 0.06%.
More DetailsThe project does not require any mining activities to be carried out by Phoenix. Processing of chromite recovered from the three mines results in the production of PGM 4Es, along with unrecovered chromite which is discarded as tailings and current arisings. The Phoenix project aims to process these tailings and current arisings to recover PGM 4Es.
