Specific gravity of iron ore -

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. get price

How to Find and Determine the Specific Gravity of a Rock

To determine the specific gravity of a mineral, you simply take a sample of ore of known size and put it into a volume of water.Weigh the water that was displaced by the mineral. This will give you the ratio between the mineral and the water. An example is if a mineral that weighs one hundred grams displaces twenty grams of water the specific gravity of the mineral is 5*0 or the mineral weighs ...

Meteorite Home Tests

Iron ore is the most common meteor-wrong. Magnetite especially is very magnetic (hence its name) and hematite may or may not be mildly magnetic. Both these minerals may possibly be distinguished from meteoritic material by a characteristic known as 'streak'. You can test the streak very simply.
