The aim of this research was to study the recycling process and the feasibility to smelt the spent nickel alyst for the production of nickel alloy or ferronickel. The smelting process was carried out in a laboratory induction furnace. The effects of SiO2/CaO for slag forming on metal recovery and smelting time were investigated. Petroleum coke was used as reductant.

Slag deposited on the bottom of a steel making furnace, especially a soaking pit for steel ingots, is difficult to remove. To enable this to be done while the furnace is hot, it is now proposed to supply a substance, ferrosilicon, which lowers the melting point of the slag, and a substance which reacts exothermically to initiate melting of the slag.
