Surface chemistry of oxidised pyrite during grinding: EDTA ...

Jan 01, 2021  As grinding progresses, fresh surfaces on pyrite particles are continuously being produced. Oxidised pyrite surfaces may also be cleaned by the impact and/or attrition mechanism with grinding balls or other pyrite particles, resulting in a decrease of iron and sulfur oxidation products on pyrite surfaces as observed in Fig. 6C.
