Processing on a hematite-limonite ore by HGMS and gravity concentration

摘要

A laboratory investigation was carried out to beneficiate a hematite-limonite ore. The ore assays 39.69% Fe and the primary iron minerals in the ore are hematite and limonite, with a relatively high S content of 0.14%. On the basis of the analysis of the ore, a "grinding-HGMS rouging and scavenging-table cleaning" process is proposed to treat the ore;;and the results of the process indicatesthat an iron concentrate assaying 48.06% Fe with 43.02% recovery was achievable from the orethrough the process, with low content of SiO_2 and deleterious elements such as S and P.
