new dry iron ore processing technology developed. as iron ore must be composed of grades of at least 58 per cent, mining companies stack the lower grade material on tailings dumps. this material with low iron content is then processed and iron is separated from other materials, particularly silica sand , from these stacks.
wet high intensity magnetic separator whims production separators overview. the reading whims set the industry benchmark for wet magnetic separation of fine minerals. they afford the most efficient separation of minerals in slurry form, when drying of the material is undesirable or uneconomical.
particles of oxidized iron ore and a magnetic separation -process and system for dry recovery of fine and superfine grained particles of oxidized iron ore and a magnetic separation unit
the processing objective here can be both the recovery of valuable iron particles and the avoidance of disruptive iron particles, e.g. upstream of membrane or ultra-filtration. wet magnetic separation. fine grain range from 1 µm to 3000 µm. steinert hgf high gradient filter.
tray to discharge non-magnetic particles and does not prevent the process of separation of a mixture of magnetic particles. scraper conveyor contains made of non -magnetic materials
if the ore particles are magnetic and the non-magnetic material is gaungethis method is used. the finely powdered ore is dropped on a belt moving on two strong electromagnetic rollers.
magnetic separation. the first pair of balls was weakly magnetized and served to d off any iron ore present. the second pair were strongly magnetized and attracted the wolframite, which is weakly magnetic. these machines were capable of treating 10 tons of ore a day.
the coarse particles are returned to a ball mill while the fine particles are fed to the second stage of magnetic separation. the ball mill will be 6.4 m x 10.7 m and contain a 35% ball charge. the final product will be 80% minus 75 microns.
