Acid leaching of CaOSiO2 resources

Waste resources containing CaO and SiO2 were leached by an acetic acid solution. Most CaO exist as calcium aluminosilicate and calcium silicate in steel slag and wollastonite, respectively. Silicate leaching was enhanced steeply by heating to 50°C or increasing acid concentrations to 4wt%. The Si an...
