Bauxite for sale is an earthy brown, red coloured sedimentary rock which on first glance, looks more like a soft clay or marl and indeed it is, being a mixture of iron and aluminium hydroxides or oxides and is a major ore, being a major source of aluminium. These particular specimens exhibit bauxite excellently, they are a deep orange or red colour, soft with a earthy texture, it stains very easily leaving a red mark on almost anything it comes into contact with. Bauxite is almost always stripped mined, this is simply because it generally forms at or near the surface of the earth with little overburden or material on top, so the need for digging or underground extractions is almost not present, allowing mining operators to extract the ore, quickly, easily, efficiently and on a massive scale. In 1821 the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. French chemist Henri Sainte-Claire Deville named the mineral “Bauxite” in 1861.

where to get bauxite, where can you find bauxite, Buy Bauxite, bauxite price per kg

• It is formed as a residual product over millions of years by chemical weathering of rocks containing aluminium silicates. It was first discovered in France in 1821, and has since been found in many locations around the world.  bauxite price

Key features

• Bauxite for sale occurrences are widespread, mostly in tropical areas where there has been intense weathering to generate bauxite, however resources are tightly held by a few competitors
• Bauxite usually occurs in a thin layer (typically 2 to 5 meters) near or at the surface
• Worldwide production is about 250 million tonnes, and has been growing at an annual rate above 5% for the past decade, driven largely by Chinese demand growth

Product details

• Bauxite is a mixture of minerals that contain various concentrations of hydrated aluminum oxides, as well as impurities. The primary ore minerals are gibbsite (alumina tri-hydrate), boehmite and diaspore (alumina monohydrates)

• Gibbsite-rich bauxite is preferred as it can be refined at lower digestion temperatures than the other types of alumina bearing minerals
• Bauxite is usually reddish-brown, but can also be white, tan, and yellow, depending on the type and concentration of iron minerals present. It also has a wide range of textures, but is typically dull to earthy in luster and can look like clay or soil

Copper for sale (Cu), chemical element, a reddish, extremely ductile metal of Group 11 (Ib) of the periodic table that is an unusually good conductor of electricity and heat. Copper is found in the free metallic state in nature. This native copper was first used (c. 8000 BCE) as a substitute for stone by Neolithic (New Stone Age) humans. Metallurgy dawned in Mesopotamia as copper was cast to shape in molds (c. 4000 BCE), was reduced to metal from ores with fire and charcoal, and was intentionally alloyed with tin as bronze (c. 3500 BCE). The Roman supply of copper came almost entirely from Cyprus. It was known as aes Cyprium, “metal of Cyprus,” shortened to cyprium and later corrupted to cuprum. In the new age Copper has been found in Africa and has a huge impact on world supply.

Native copper is found at many locations as a primary mineral in basaltic lavas and also as reduced from copper compounds, such as sulfides, arsenides, chlorides, and carbonates. (For mineralogical properties of copper, see the table of native elements.) Copper occurs combined in many minerals, such as chalcocite, chalcopyrite, bornite, cuprite, malachite, and azurite.

It is present in the ashes of seaweeds, in many sea corals, in the human liver, and in many mollusks and arthropods. Copper plays the same role of oxygen transport in the hemocyanin of blue-blooded mollusks and crustaceans as iron does in the hemoglobin of red-blooded animals. Gold for sale

The copper present in humans as a trace element helps catalyze hemoglobin formation. A porphyry copper deposit in the Andes Mountains of Chile is the greatest known deposit of the mineral. By the early 21st century Chile had become the world’s leading producer of copper. Other major producers include Peru, China, United States and mainly Africa.

Our Copper is commercially produced mainly by smelting or leaching, usually followed by electrode position from sulfate solutions. For a detailed treatment of the production of copper, see our copper processing. The major portion of the copper we produce is used by electrical industries; most of the remainder is combined with other metals to form alloys. (our copper is also technologically important as an electroplated coating.)

Important series of alloys in which copper is the chief constituent are brasses (copper and zinc), bronzes (copper and tin), and nickel silvers (copper, zinc, and nickel, no silver). There are many useful alloys of  our copper and nickel, including Monel; the two metals are completely miscible.Our  Copper also forms an important series of alloys with aluminum, called aluminum bronzes. Beryllium copper (2 percent Be) is an unusual copper alloy in that it can be hardened by heat treatment.

Our Copper is a part of many coinage metals. Long after the Bronze Age passed into the Iron Age, copper remained the metal second in use and importance to iron. By the 1960s, however, cheaper and much more plentiful aluminum had moved into second place in world production.
