The process of grinding of coarse particles of glass-like slag from the ferro-nickel industry in a high-speed ball mill has been studied. The disintegration of slag particles first occurs at the places of ferrous oxide accumulations. Then, the glass-like component of slag particles (calcium silicate) is destroyed accompanied with the formation ...

Ferronickel is an alloy containing nickel and iron - approximately 35% nickel and 65% iron. Its uses The use of nickel is dominated by the production of ferronickel for stainless steel (66%). However, it is also used in the production of non-ferrous alloys (12%), alloy steels (5%), plating (7%), foundry (3%) and batteries (2%).

Rotary kiln-electric furnace (RKEF) process is the main technology to deal with nickel laterite for the ferronickel alloy production in the world. However, this process needs huge amount of electric power due to the large ratio of slag to metal. Therefore, a novel process was proposed to directly produce ferronickel alloy nugget at a related ...
