Calcite Massed In Air

Galena Massed In Air

Sulfur Massed In Air

Calcite Massed In Water

Sulfur Massed In Water

To Find Specific Gravity

Divide the Mass in Air

By The Mass Lost in Water

Non-Metal Calcite = 2.7

Metal Chalcopyrite = 4.2

Non-Metal Sulfur = 2.1

Metal Galena = 7.5

How can a liquid with SG of 5.1

Be used to distinguish Pyrite SG 5.0

from Magnetite SG 5.2?

Halite can not be tested

in this way! Why?

Non-Metals Have SG Below 3 and Metals Have SG Above 3
