Abstract:Using optical microscopy, XRD, SEM, and EDS, the effects of diverse coals on the reduction behavior of tin-bearing iron concentrate pellets were studied in this research. The results indicated that anthracite and coke breeze could be used as suitable reducers to separate tin from the tin-bearing iron concentrate pellets. Lignite and semi-coke with good reactivity accelerated the generation of metallic iron and metallic tin and caused Fe–Sn alloy to easily form in the reduced pellets; this had an adverse effect on tin volatilization from the roasted pellets. When using anthracite and coke breez
