Sepn. of liq. and solid phases after leaching uranium ore - where gypsum is added to hot sulphuric acid leaching soln. to aid filtration and increase uranium yield in filtrateTo improve the sepn. of undissolved matter, gypsum (CaSO4,2H2O) is added simultaneously with the ore to an aq. ...
All the water is evaporated by the thermal energy of flue gas during sufficient residence time for SO2 and other acid gases (HCl, SO3) to react with hydrated lime, which forms a mixture of solid calcium compounds (CaSO3, CaSO4, CaCl2). Since all the water is evaporated, the mixture of ...
2CaOCl2 + H2SO4 → CaCl2 + CaSO4 + 2HOCl 2HOCl → 2 HCl + 2 [O] When it is treated with excess of dilute acids, chlorine is evolved. Chlorine gas produced in this way is known as, “available chlorine” which is responsible for the bleaching action of bleaching power. Available ch...
