hello Friends this is my first time that i make this process. i putt a few grams of gold foils that i removed from ram sticks . to a beaker whit 150 ml aqua regia . the gold was dissolved and the solution was yellow. in stanuss test i dont got eny reaction. so i thought the solution contain...

iron: Production and Refining | Infoplease

Gray iron is brittle but soft and easily machined. White cast iron, or white iron, which is harder and more brittle, is made by cooling the molten iron rapidly. The carbon remains distributed throughout the iron as cementite (iron carbide, Fe 3 C). A malleable cast iron can be made by annealing white iron castings in a special furnace.

Notes OCCURRENCE AND EXTRACTION OF METALS

16.2 GENERAL PRINCIPLES OF EXTRACTION OF METALS The process of extracting the metals from their ores and refining them is called metallurgy. The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore.

Extraction of Metals: Concentration of Ore, Refining of ...

Extraction of Metals: Concentration of Ore, Refining of Impure Metal. Extraction of Metals- A metal is a material that is extracted from the ore. When it's been freshly prepared, polished, it shows a lustrous appearance and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ...

25.5 Refining minerals | Mining of mineral resources ...

We will discuss the extraction of iron from iron ore as an example. Extraction of iron. Iron atoms are found in the compounds FeO, Fe 2 O 3 and Fe 3 O 4 and in rocks like haematite and magnetite. South Africa is the seventh largest producer of iron ore in the world. Iron has been mined in South Africa for thousands of years.

nickel processing - Extraction and refining | Britannica

Extraction and refining. The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

How iron is made - material, manufacture, making, history ...

The Ore Extraction and Refining Process Before iron ore can be used in a blast furnace, it must be extracted from the ground and partially refined to remove most of the impurities. Leaning on his long tongs, this young iron puddler's helper posed for this photograph in the early 1860s, when the Sons of Vulcan was a young union.

Relation of iron to platinum family metal extraction ...

Your profile says you are in the USA. Where the ore types you are saying you have are extremely rare,. Platinum, or platinum group metals in the united states have only been found in a couple of locations, and with mining restrictions nowadays, it has been harder and harder to do much of any mining of many of the metals, and with the rarity of these PGM metals in the US very little of these ...

metallurgy - Refining | Britannica

metallurgy - metallurgy - Refining: Refining is the final procedure for removing (and often recovering as by-products) the last small amounts of impurities left after the major extraction steps have been completed. It leaves the major metallic element in a practically pure state for commercial application. The procedure is accomplished in three ways: refining by fire, by electrolytic, or by ...

Refining (metallurgy) - Wikipedia

This process oxidised the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal, known as finers metal or refined iron. Precious metals. Precious metal refining is the separation of precious metals from noble-metalliferous materials.
