Gravity separation or hydraulic washing. The gravity separation method, also known as hydraulic washing, is used for metals that are heavier than the gangue particles. In this method, water is used to enrich the ore. The ore is passed through a stream that goes upward, pushing up all the lighter particles mainly comprising impurities, while the ...Web

The fly ash from most of the U.S. bituminous coals contains 15 to 20 weight percent iron oxides, 50% or more of which can be recovered by dry magnetic separation as a high density fraction. The density of this fraction is 3.5 to 4.0 g/cm/sup 3/, depending on the fly ash. Most of the particles are spheroidal, and the maximum size is less than ...Web

The ash contents of the feed coal reporting to the overflow and underflow have been analyzed qualitatively. The result indicates that the use of magnetite as dense medium in DMC resulted in the yield of clean coal, which is 5% more when the air core is suppressed as compared to the same conditions when the air core remains.Web

The richest ore of iron is magnetite. Magnetite has an iron content of up to 72.4%, which is higher than hematite. However, magnetite is more difficult to process than hematite due to its high levels of impurities. Magnetite is typically found in large deposits and is commonly used in the production of steel.Web
