What is the difference between Aluminium Refining and Aluminium Smelting? For Chemistry Assignment.
gizmoe is correct second heatingcooling system is the only true way to get the desired temp on both floors12 in minimum insulation if possible.
i would pick radiant barrier roof.and more insulation in the attic while they were up there why not do both and save alot on your energy bills.
more isolation in the attic is better .
If I had to pick one or the other, I'd go w/the radiant barrier roof nowIdeally you want both but additional insulation can be added laterTemp equilibrium between floors is best handled by zoning (single HVAC system) or have a separate system for each floor (preferred)Based on my experiences w/two story structures I don't believe the roof or insulation choices will have much bearing on this issue as hot air rises and cold sinks.
Refining :- (as in non-metallurgical uses) consists of purifying an impure material, in this case a metalIt is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purerThe processes used are of many types, including pyrometallurgical and hydrometallurgical techniquesSmelting :- is a form of extractive metallurgy; its main use is to produce a metal from its oreThis includes iron extraction (for the production of steel) from iron ore, and copper extraction and other base metals from their oresSmelting uses heat and a chemical reducing agent, commonly a fuel that is a source of carbon such as coke, or in earlier times charcoal, to change the oxidation state of the metal oreThe carbon or carbon monoxide derived from it removes oxygen from the ore to leave the metalThe carbon is thus oxidized, producing carbon dioxide and carbon monoxideAs most ores are impure, it is often necessary to use flux, such as limestone, to remove the accompanying rock gangue as slaghope its work Enjoy
