· Water molecules are removed as part of iron ore beneficiation. One of the approaches to iron ore beneficiation first involves a basic screening or filtering of the ore and then crushing it using equipment like a jaw crusher to break up the rock from its natural state down to individual block or rock sizes with dimensions of length or height no greater than 3.3 feet (1 meter).
Beneficiation of Low Grade Iron Ore with grade with Fe content 38.86%, beneficiation is done with magnetic separator, but to improve until 60% Fe content, it get a size 10 to200 mesh iron ore. Iron ore results of screening washed using water in the cylinders
· The sample with 85 wt% passing 0.074 mm was air-dried. The iron ore sample was characterized using chemical analysis and XRD, and the results are shown in Table 1 and Fig. 1, respectively. The content of valuable metal Fe is 34.6 wt%, and the main phase structures of the sample are hematite (Fe2 O 3) and quartz (SiO2).
