Review on comprehensive utilization of nickel laterite ore
Nickel laterite ore smelting slag is a byproduct of the ferronickel alloy production process. Due to the low nickel content in the ore, a substantial amount of slag is generated. Nickel-iron slag has become the fourth largest type of slag produced in smelting processes, following iron slag, steel slag, and red mud(Xi et al., 2018).
