Chemistry 1210 Normality/Redox Problems 1) A sample of iron ore weighing grams was dissolved in dilute acid solution, and all of the iron was converted to Fe(II) ions.
An ore is an impure form of mineral, so it can't be given exact chemical formula. Whereas a mineral is pure compound(in general, and can be used to obtain pure elements like metals) so it has an exact chemical which can used to obtain the metal profitably are called minerals are not ores but all ores are essentially ...
A. Concentration or Benefaction of the Ore. This is a very important in metallurgy. The ore is obtained from the earth and usually contain dust, stone, quartz, feldspar and other foreign impurities are known as gangue or matrix. The process of separation of .
