FERRONICKEL PRODUCTION AND OPERATION REFINING OF FERRONICKEL . (transportation ladle, converter vessel, treatment ladle or electric arc furnace). The usage of converters in the refinery process is advantageous compared to the ladle furnace route ifthere is a very high starting carbon (C > 0.60 %) or silicon (Si> 1.00 %) content. In some .
slag dump is constructed of which the capital and running costs are way in excess of those of a slag granulation plant. Processing of such slag-dumps is very labour intensive and costly, where crushing and screening plants are utilised to reduce the slag-dumps by either recycling or jigging to remove alloys, or to convert it into a backfill .
