The carbonate ores are changed into oxides by heating strongly in limited air. This process is called calcination., in this Carbon dioxide is form.
ex: ZnCO^3(s) when heated it gives ZnO(s) + CO^2(g)
^2 nd ^3 ..this means that the no..are in squares nd cubes..!!
Several reports on Microwave Assisted Calcination methods were made in 2006 and 2011 years.
In alchemy, calcination was believed to be one of the 12 vital processes required for the transformation of a substance.
Alchemists distinguished two kinds of calcination, actual and potential. Actual calcination is that brought about by actual fire, from wood, coals, or other fuel, raised to a certain temperature. Potential calcination is that brought about by potential fire, such as corrosive chemicals; for example, gold was calcined in a reverneratory furnace with mercury and sal ammoniac silver with common salt and alkali salt; copper with salt and sulfur; iron with sal ammoniac and vinegar; tin with antimony lead with sulfur; and mercury with aqua fortis
