Galena Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.. Galena is one of the most abundant and widely distributed sulfide minerals.It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluoriteOre Lead ore galena and anglesite (size 4.8 × 4.0 × 3.0 cm) Gold ore (size 7.5 × 6.1 × 4.1 cm) Minecart on display at the Historic Archive and Museum of Mining in Pachuca, Mexico.

9.3 Types of Ore Deposits 9.3.1 Magmatic Ore Deposits 9.75 Goldbearing quartz vein at the Nalunaq Gold Mine in Southern Greenland. Meter stick for scale. Minerals containing elements of economic value are generally present in all igneous rocks, but the elements may not be concentrated enough to make mining economical.

Hardness is 1.5 to 2, color and streak are steel gray to silver white, and specific gravity is 8.1. Sylvanite and the other tellurides (calaverite and krennerite) are mined from igneous rocks in the nearsurface, lowtemperature veins at Cripple Creek, Colo., and in the deeperseated deposits at Kalgoorlie, Australia.

The Specific Gravity SG is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference at this point the density of water is at the highest.. Specific gravities SG for common solids and metals can be found in the table below

May 01, 2014· Galena Galena may look dull, but it can have deadly sideeffects. Credit Saleta. Most lead miners seek galena ore, a lead sulphide mineral that also proves a reliable source of silver. The rock has a relatively low solubility, meaning that it does not easily dissolve into water. Often, it forms as a crystal.
