Research on Utilizable Calcium from Calcium Carbide Slag with Different Extractors and Its Effect on CO Mineralization.

With the increasing accumulation of alkaline industrial solid waste, the mineralization of CO using alkaline industrial solid waste has broad application prospects. Carbide slag is highly alkaline and contains a large amount of calcium elements, making it an excellent material for CO mineralization. Our idea was to acquire qualified products and fast kinetics by integrating carbide slag utilization and carbon reduction.
