What is a melting plant?
Tearstation plant is an industrial place where the metal is extracted for raw ore. Common examples of metal melting include tin, lead, copper, bronze and iron. Pure aluminum extraction is also called melting, although the process is significantly different from the process of other ores. Ruda is generally defined as a rock or a group of minerals that has a potential economic value. Ruda contains not only metal. For example, iron ore is a rock that contains iron tied to other chemical compounds and minerals. The melting ore is the process of eliminating interest from its original rock. The ore must be heated in the oxidation environment until the chemicals start to mobilize or be available. Some impurities can be taken away by heat, and if the metal that is interesting in the form of sulfide, Onat and the presence of oxygen can be sufficient to convert to oxide. However, it is not possible to simply melt the metal from ore.
In addition to heat, the melting also requires a reduction agent. The main metal probably exists like oxID or will be converted into oxide during initial heating. A sufficiently strong reduction agent will be able to convert oxide to clean metal and some waste product.
One of the first examples of the melting plant was the flower that the blacksmith used to feel iron ore. In flower iron ore warms in the presence of coal or clean carbon fuel and moving air. When ore warms them, carbon monoxide from coal reduces iron oxide.
Terms reaction in flowering produces relatively pure iron metal and carbon dioxide as a waste product. As the bellows blows through the flower, carbon dioxide is evacuated, allowing to continue the reaction. Metal and dirt, called slag, fall to the bottom of the furnace when iron ore is reduced. Iron is usually heated for the second time to pull a slag from the forged iron.
Another early form of iron melting is an explosive furnace that has a particularly old history in ChinaOria. In the mid -18th century, however, iron ore was melted into steel, which is a much cleaner form of iron metal. This industrial transition to steel was made possible by the development of the Bessemer process, in which the air blown with molten iron is able to remove most of the dirt. Starting in 1950, the dominant method of extraction found in a given iron melting plant has become the basic form of oxygen steel (BOS). BOS improves the basic bessemer process by blowing pure oxygen with molten iron, which drastically improves the efficiency of the melting plant.
Many other metals are subject to melting method of extraction and many techniques of different melting plants and melting devices are governed by the same basic principles. In addition, aluminum extraction is also called melting. Aluminum melting plants differ in that they perform an electrolytic process. The electric current passes through a liquid molten cryolite in which the aluminum oxide was dissolved. Corresponding oxidation and reduction that occurs on eLlectric anode and cathode, convert aluminum oxide into pure aluminum.
