beneficiation of iron ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. this also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. all such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500,taconite duty - nidec,protection against such fine particles is required. taconite is a low-grade iron ore found as a hard rock. before it is transported to steel mills it is concentrated to pellets in processing plants. the amount of airborne taconite dust in these processing plants will vary depending on the amount of dust abatement equipment available.
