The use of tantalum has expanded dramatically since the 1940s as a result of major advances in electronics. The principal source of tantalum until the 1990s was tin mining, where tantalum was extracted as a by-product. By the 1990s the main source of tantalum came from the extraction of specific tantalum ores in different parts of the world.
The more active (or reactive) a metal is, the more stable the compound it forms and the greater the energy required to produce the metal from its ore. Very active metals ( Group 1, Group 2 and aluminium) require electrolysis to extract the metal while very inactive metals like gold and silver can occur in nature as the element so require no ...
Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, …
Products made from iron ore. Iron ore is a mineral substance heavily comprised of iron oxides, primarily hematite (Fe203) and magnetite (Fe304). While mostly unusable in its native form, when mixed with a reductant and heated it produces metallic iron (Fe).
The hot metal spread is similar in concept to oil 'crack spreads' in the sense that they represent a pricing and ... benchmark for relational pricing of other iron ore grades or even of finished products that relate to it. If that is the case, 58% and 65% iron ore may trade at …
Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin is soft enough to be cut with little force. When a bar of tin is bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and frozen mercury.
Founded in 1963, Thailand Smelting and Refining, better known as THAISARCO, is a private firm that manufactures tin, tin alloys and tin-related value-added products. In …
chromite ore production in various forms of imported materials, such as chromite ore, chromite chemicals, chromium ferroalloys, chromium metal and stainless steel. Used as an alloy and in stainless and heat resisting steel products. Used in chemical and metallurgical industries (chrome fixtures, etc.) Superalloys require chromium. It is

Solder, the outside of cans and cooking utensils, are traditionally made of tin. While tin is still a very common metal in the United States, aluminum is generally used in place of tin because it is less expensive. The most common use of tin is in the production of solder. Solder works as somewhat of a liquid metal and is able to hold joints ...
Tin reserves of the world, exclusive of the U.S.S.R. and China, at a price be tween $2,000 and $3,080 per long ton (2,240 pounds) of tin, are estimated to be at least 3,500,000 long tons in 1970 ; tin resources of lower grade are estimated to

Tin extraction and use can be dated to the beginnings of the Bronze Age around 3000 BC, when it was observed that copper objects formed of polymetallic ores with different metal contents had different physical properties. The earliest bronze objects had tin or arsenic content of less than 2% and are therefore believed to be the result of unintentional alloying due to trace metal content in the ...
The flowsheet below Explains the Extraction of Tin Ore as shown by a study adapted to the concentration of a lode tin deposit.Cassiterite (SnO2) is very friable and special considerations to crushing and grinding of the ore are necessary to avoid an excessive production of fines. The Mineral Jig is an important feature of this flowsheet to recover the coarse free tin mineral as soon as liberated.
