The heart of the separator is an airtight bowl with funnellike stainless steel disks. The bowl is spun at a high speed about 6,000 revolutions per minute, producing centrifugal forces of 4,000 to 5,000 times the force of gravity. Centrifugation causes the skim, which is denser than cream, to collect at the outer wall of the bowl.
The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and includeite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70 down to 20 or less.
In the first method, a machine called a hydraulic giant uses a high pressure stream of water to knock the gold ore off of banks containing the ore. The gold ore is then washed down into sluices or troughs that have grooves to catch the gold.
To separate the tiny quantity of uranium 235 that is present in every natural sample of uranium ore, engineers first use a chemical reaction to turn the uranium into a gas, said Jeff Binder, the
Gold ore extracted from mines in the earth contains a significant amount of impurities, including traces of other metals. In order to separate the gold from other metals, chemicals such as cyanide solution or mercury are introduced to the gold. This process causes the gold to coagulate, and form nuggets and clumps of gold. Video of the Day

Copper processing isplicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday use.Themon types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
Extracting iron from iron ore using a Blast Furnacemon ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.

Gold extraction refers to the processes required to extract gold from its ores.This may requirebinationminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting
Decanting. Decanting involves separating a dense, insoluble substance from a heterogeneous mixture. For example, if we mixed sand with water in a beaker, the sand would not dissolve, but would settle to the bottom, forming a sediment layer. By gently pouring off the water the supernatant, we could separate the sand from it. In the laboratory, using a glass rod can assist the decanting
