The use of specific gravity in determining the grade of iron ore is not a new procedure. Eckel 1910, p. 38 pointed out the approxi mate correlation between specific gravity of the Alabama iron ores and their iron content. Feld, Coe, and Coghill 1946 devised a rapid specific-gravity method for estimating the iron content of powdered

Just as useful as density, however, is the specific gravity. Specific gravity is the ratio of the mass weight of a rock to the mass of the same volume of water. Water has a density of 1.0 gcm 3, so the numeric value of specific gravity for a rock is the same as that for density. Because specific gravity is a ratio, it has no unit.

Aug 16, 2021 Abstract The studies concerning ore-dressing waste processing at the enterprises of the Kursk Magnetic Anomaly with the production of metals and building materials are described. About 1.8 billion tons of tailings have been stored there. A significant feature of deposit formation consists in the division of tailings by size and specific gravity using a water flow, since tailings are ...

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Todays commercial taconites contain 25 to 30 iron by weight.
