Pyro-Hydrometallurgy Routes to Recover Silica from Indonesian Ferronickel Slag

Recycling, 2023
Ferronickel slag is a by-product of nickel smelting that provides an abundant silica source. Based on data, every ton of nickel production is equal to eight tons of ferronickel slag production, increasing without any recycling process. It is essential to
