Question

Distinguish between flux and slag. Which metals are generally extracted by the electrolytic processes? What positions do these generally occupy in the periodic table?

Answer 1

We know that the flux is a substance or a material that we add in molten metal at the time of refining of metals to form a bond with impurities that can be easily removed afterwards. Slag is a waste material which is being removed.

Complete answer:
As we know that the Flux is a substance which we add to molten metal to bond with impurities that can be removed afterwards, slag is a waste material which is removed. Fluxes are used during refining of metals and slag is impure residue. Gauge is the impurity in ore which is difficult to remove. The waste materials which are accompanied with minerals while extracting are called Gangue particles. It is earthly impurities and does not have any electrical or magnetic properties. Gangue has no value in the market and it is waste rock or sand or soil. It is present along with minerals in the ore deposit from which the metal is to be extracted. Gangue is different from the waste rock which is present above the ore deposit. The pieces of rocks which are already stripped of by natural process are called tailings. Flux is a chemical substance used to convert impurities which are not easily removed whereas slag is a substance which is easily removed when flux and gauge are together.
Flux is that the material or substance that is another to liquefied metals to bond with impurities which will be pronto removed whereas scum is that the waste that is removed. Fluxes area unit used throughout the refinement of metals examples area unit acid oxide, basic lime, etc. the selection of flux depends on the fabric concerned within the given operation Slag is impure residue that contains great amount of calcium, magnesium silicate, iron, aluminium etc. derived throughout the method of Fe and production and through the smelting of metals like copper, lead and nickel.
When electricity is passed there'll be an opportunity to down chemical compounds, this method is termed electrolysis. A conductor is going to be placed within the liquid solution wherever one conductor is charged that is cathode and one is going to be charged that is anode. Reduction happens at cathode and reaction happens at anode Potassium, sodium, calcium, magnesium and aluminum area units extracted by electrolysis. They kind stable compounds

Note:
Remember that in metallurgy different processes are studied which are used to extract metals. Metals are extracted through minerals and ores. All the ores are minerals but all the minerals are not ores.
