duty. In the iron ore industry, most of the machines are found in pellet feed applications. How-ever, there are a few notable examples where HPGRs are used for coarse iron ore grinding – in Chile, Mauritania and the USA. The first large scale attempt at applying HPGRs to harder and more abrasive copper and gold ores was in 1996 at Sierrita.
In this study, a process to separate manganese and iron from manganiferous iron ores by reductive acid leaching followed by magnetic separation was conceived and experimentally tested. In the leaching process, sulfuric acid was used as lixiviant and oxalic acid was used as reductant. The experimental results showed that the manganese and …
