Iron Ore Tailings Processing Overview

iron ore processing - an overview | sciencedirect topics,in india, where iron ore processing is one of the major industries, the generation of tailings is estimated to be 10-25 % of the total iron ore mined, amounting to 18 million tons per year (das et al., 2000). the tailings contain silica in high percentage (40-60 %, from various locations)..summary of iron ore beneficiation process and technology,there are many mineral processing methods, and there are two commonly used methods (1). roasting magnetic separation roasting magnetic separation is one of the effective methods to separate fine to fine (< 0.02mm) weakly magnetic iron ore. when the minerals in ore are complex and it is difficult to get good indexes by other methods, magnetization roasting magnetic separation should be used..
