Insights into solidification mechanism of Cr(III) and Cr(VI) in chromite ore processing residue via composite geopolymers synthesized from calcined red mud and granulated blast furnace slag
{{output}}
Chromite ore processing residue (COPR), which contains soluble toxic Cr(Ⅵ), is a hazardous waste from chromium salts production process. The pre-reduced COPR was solidified using composite geopolymers synthesized from the calcined red mud (RM) and the granula... ...
