University of Minnesota's Mineral Pages: Galena

The Roman naturalist Pliny may have been the first to record the use of the name 'galena' for lead ore. Galena (lead sulfide) is easily the most important source of lead, and often contains enough silver impurities that it is also a valuable source of that metal.

Cerussite

It has a Mohs hardness of 3 to 3.75 and a specific gravity of 6.5. A variety containing 7% of zinc carbonate, replacing lead carbonate, is known as iglesiasite, from Iglesias in Sardinia, where it is found. The mineral may be readily recognized by its characteristic twinning, in conjunction with the adamantine lustre and high specific gravity.

Lead-Zinc ores. However, because of the high float kinetics and high galena mineral density, the mineral froth carrying capacity may necessitate use of a slightly stronger frother or a combination with a stronger frother component for achieving optimum metallurgical results.

Treatment of lead mine waste by a Mozley multi

The material requiring treatment is from abandoned lead/zinc mines in Balıkesir/Balya, Turkey which were mined between 1880 and 1935 and were abandoned as their silver and lead content decreased. Lead ore was produced by underground mining and concentrated by the application of gravity separation and flotation processes.

IMPORTANT ORE MINERALS

This concentration is usually accomplished by dissolution of the element by hot water (hydrothermal ore deposits - gold, silver, lead), preferential crystallization from magmas (chromite deposits or pegmatites), surface weathering and leaching (aluminum, nickel, copper), or gravity separation of minerals during erosion (gold, diamonds, titanium).

Find the reciprocal of the specific gravity of each metal in the alloy. This is done by dividing 1 by the specific gravity. For example, the specific gravity of silver is 10.49 and the reciprocal is 1 divided by 10.49 or 0.094966. Multiply each reciprocal by the number of parts per thousand of that metal to be used.
