Ore and base metals are weighed in Avoirdupois long or short tons or in metric tons. 1 metric ton = 1000 kilograms. 1 long ton = 2240 pounds. 1 short ton = 2000 pounds. Precious metals are weighed by metric or troy weights. The common weights in the metric system are the following: 1 metric ton = 1000 kilograms (kgs.) 1 kilogram = 1000 grams (g.)

Magnetite (Fe 3 O 4) ore is concentrated by lowmagneticfield drums to recover a magnetite concentrate that is low in silica (SiO 2). The presence of SiO 2 in the magnetite concentrate for steel production increases the steel processing costs, so a major challenge in magnetic concentration is to lower the SiO 2 grade in the Fe concentrate.
