Explain the following observation: the most important ore of aluminum is bauxite, a hydroxylated form of Al 2 O 3, whereas the most common ore of lead is galena (PbS).
Of the more than 60 known leadcontaining minerals, by far the most important primary ore of the metal is the lead sulfide galena (PbS). Galena often contains silver, zinc, copper, cadmium, bismuth, arsenic, and antimony; in fact, the value of the silver content often exceeds that of the lead, in which case it is deemed a silver ore. Other commercially significant leadcontaining minerals are

· While lead does occur (rarely) in nature in its pure form, most of the lead produced today comes from recycled batteries. Lead is found in the mineral galena (PbS) and ores of copper, zinc, and silver. Lead is highly toxic. The element primarily affects the central nervous system. It is particularly dangerous to babies and children, where lead exposure can stunt development. Lead is a ...
The most important lead mineral of the sulfide group. It is easily distinguished by its good cleavage, diagnostic leadgray color high specific gravity (SG=) and hardness (H=2 1/2). Is a relatively common sulfide and it is found in veins associated with many minerals including pyrite calcite, fluorite, and barite Use: It is the major source of lead, which is used for batteries, in making ...
Lead is hardly obtained from lead ore anymore, however, but instead from recycled lead scrap. Today, more than 50 per cent of global requirements can be met from this. In 2005, the demand for lead ...
Galena is used as the most important ore of lead. What metals come from galena ore? The ore galena (lead II sulfide) is the major source of lead. Cerussite is the ore of what metal?
· What is an Ore? Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. For example, iron ore is used to make iron and steel. Here, we providing a List of some Important metals and their ores. it is mainly useful for your upcoming competitive exams like SSC, UPSC etc.
Today, lead, which has been mined on all continents except Antarctica, is one of the most important metals to industrialized economies. Galena, a lead sulfide mineral (PbS), is the primary ore of lead. It is mined at many locations worldwide. Related: Galena the Primary Ore of Lead. Modern Uses of Lead .

The most important lead ore is galena (PbS). Other important ores, such as cerrusite (PbCO 3) and anglesite (PbSO 4), may be regarded as weathered products of galena and are usually found nearer the surface. The primary manufacture of lead involves three stages: a) ore concentration b) smelting c) refining (a) Ore concentration. Lead and zinc ores (usually sphalerite, ZnS) often occur together ...
Vanadinite is mineral composed of lead, vanadium, oxygen and chlorine. It is one of the most important ores of vanadium and a minor ore of lead. Its bright colors, high luster and interesting crystals make it popular with mineral collectors.
Galena, a lead sulfide, PbS, is the most important ore mineral of lead. Its metallic, lead gray cubic crystals (isometric system) and cubic, perfectly cleavable masses are distinctive and characteristic. Streak lead gray.

most important ore of lead . The most important ore of lead is galena or lead glance PbS, which is widely distributed throughout the world Other ore minerals of lead are anglesite, cerussite, pyromorphite, and mimetesite Other lesser minerals are crocoite (or kallochrome, or redlead ore.
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 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.
Most elements need to be concentrated into amounts that can be economically mined from ore deposits (usually hundreds to thousands of times their crustal abundance). 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 ...
Depending on the type of ore and degree of required purity, the extraction process typically includes concentration, smelting, and refining. In nonferrous metal smelting operations, each element is refined from very complex compound material in which the major elements are copper, zinc and lead. When smelting copper, it is very important to ...
Although lead (Pb) rarely occurs naturally in its elemental state, it has been used by man throughout history. One reason for this is that its principal ore, lead(II) sulphide known as galena, is easily recognised and readily reduced by heating with charcoal.
