Concentrate Grade - an overview | ScienceDirect Topics
In oxidized iron ores, it is usually easier to obtain a higher-Fe grade concentrate from specularite using magnetic separation, because its grains are better crystallized. In Figure 9.12, SLon magnetic separators are used for processing a specularite ore containing about 35% Fe. The run-of-mine ore is mainly composed of specularite and quartz.
