Q. What is Calcinations process?
This is fie method of heating the concentrated ore in a limited supply of air to a high temperature but under the fusion temperature. In calcinations, volatile constituents of an ore are expelled. Hydrated and Hydroxide ores lose their water forming metal oxides. In case of carbonate ores, carbon dioxide is lost and metal oxides are made.
Ernest Rutherford in 1909 conducted what is now a famous experiment where he bombarded gold foil with alpha particles (Helium nuclei). A source which undergoes for alpha decay is
