Which material formed during smelting is denser molted metal or slag?
The molten metal is the denser material, the slag floats on top of it and can be "scooped" off during the smelting process.
What are stony waste matter separated from metals during smelting of refining?
slag
What was the first metal extracted?
aluminum
What is meant by - smelting?
Smelting is the process which ore goes through so that a metal can be extracted from it. It involves heating the rock to very high temperatures. Copper, for instance, can be extracted at temperatures of about 1200 °C.Actually, smelting is a process when a metal which is more reactive than copper needs to be extracted. For example, zinc is more reactive than copper so it has to be extracted smelting. It can be extracted by heating its ore with charcoal aka smelting.--different person
Sandstone removes unwanted elements from metal being processed?
It is actually smelting, not sandstone.
Which material formed during smelting is denser molted metal or slag?
The molten metal is the denser material, the slag floats on top of it and can be "scooped" off during the smelting process.
What is slag a rock?
A slag rock is an artificial rock. Slag is made as a byproduct of industrial processes such as metal mining. It is also produced by iron smelting such as in steel mills.
What is waste from smelting called?
Slag or dross. Both are byproducts of separating the elements of liquified metal ore.
What is the smelting point of a metal?
Smelting is a form of extractive metallurgy; its main use is to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, or in earlier times charcoal. The carbon (or carbon monoxide derived from it) removes oxygen from the ore, leaving behind elemental metal. The carbon is thus oxidized in two stages, producing first carbon monoxide and then carbon dioxide. As most ores are impure, it is often necessary to use flux, such as limestone, to remove the accompanying rock gangue as slag. However, the temperature (smelting point according to the question) for this reaction will vary for each metal.
What is difference between gangue and slag?
Gangue is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed or simply rocky impurities.While slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.
What is slag?
Slag is a byproduct generated during the smelting or refining of metals. It is a mixture of impurities and waste materials that are separated from the desired metal during the cooling process. Slag is often used in construction and road building due to its durability and ability to improve the characteristics of concrete.
After miners remove ore from a mine what process removes the metal from the ore?
Smelting
What are stony waste matter separated from metals during smelting of refining?
slag
What is the difference between metal melting and metal smelting?
Smelting extracts a metal from its ore. Melting liquifies the metal.
What is the formulae for slag?
Slags are basically artificial silicates of varying formula. The is no overall formula for slag because it is dependent on the ingredients used and just what is being smelted. For example slag from iron smelting is different than from copper smelting. The most important aspects of slags are that they contain all the unwanted materials while allowing an economic separation of the valuable constituents of the ore. The chemistry of a given slag depends on the waste components of the ore plus the fluxes used to slag them off.
What is smelting?
A process of taking an oreand, throughheating and adding other substances to remove other elements, gives you a purer sample of the metal.
What is slag from welding?
Slag is the residue left on a weld bead from the flux. It shields the hot metal from atmospheric contaminants that may weaken the weld joint. Slag can also be globules of molten metal that are expelled from the joint and then re solidify on the metal surface. in either case, they are usually chipped away with a slag hammer.
