This means the individual granules are finer than table salt. The texture is something like granulated sugar. Flotation 3 The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral.

Description and origins of Galena, a sample of the element Lead in the Periodic Table.
'Young' (post-Cambrian) carbonate-hosted zinc-lead deposits have galena-lead isotope ratios (Table 1) that plot within the Devono-Mississippian shale cluster but are dis- tinct from shale clusters of other ages (Figs. 71 and 731.
Lead: Lead, a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. Lead is very malleable, ductile, and dense and is a poor conductor of electricity. Known in antiquity and believed by the alchemists to be the oldest of metals, lead is highly durable and resistant to corrosion.
Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite.Trace amounts of other elements including gold are sometimes found with lead ore. The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS.
Lead is found very rarely in the earth's crust as a metal. Normally, lead is in the mineral galena. Galena is lead sulfide. Galena is the main lead ore. History. Lead was used for thousands of years because it is easy to get from the ground and easy to shape and work with. The Romans used lead very commonly.
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide. 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.
Galena is the most important source. Abundances of lead in various environments. In this table of abundances, values are given in units of ppb (parts per billion; 1 billion = 10 9), both in terms of weight and in terms of numbers of atoms. Values for abundances are difficult to determine with certainty, so all values should be treated with some ...

Galena (lead ore) weighs 7.5 gram per cubic centimeter or 7 500 kilogram per cubic meter, i.e. its density is equal to 7 500 kg/m³. In Imperial or US customary measurement system, the Galena (lead ore) density is equal to 468.21 pound per cubic foot [lb/ft³], or 4.3 ounce per cubic inch [oz/inch³] .
Galena is a noticeably dense mineral, having a density of about 7.6 gm/cm 3.It has a metallic luster. Galena has the same cubic structure as common table salt, NaCl. The samples pictured here are on display at the Smithsonian Museum of Natural History.
Lead is the fifth element of the fourteenth column in the periodic table. It is classified as a post-transition metal, a heavy metal, and a poor metal. ... It combines with other elements to make a variety of minerals including galena (lead sulfide), anglesite (lead sulfate), and cerussite (lead carbonate).

lead minerals (galena). Lead (Pb) is dominant while zinc (Zn) serves as a minor element. The Chemical composition of lead concentrate was examined through AAS as shown in Table 1. It depicted that the concentrate was dominated by lead (Pb) and sulfur (S). Zinc (Zn) and irons (Fe) were not too high. The chemical analysis confirms
