Electrolysis Wikipedia

Electrolysis of water produces hydrogen and oxygen in a ratio of 2 to 1 respectively.. 2 H 2 O(l) → 2 H 2 (g) + O 2 (g); E 0 = +1.229 V. The energy efficiency of water electrolysis varies widely. The efficiency of an electrolyzer is a measure of the enthalpy contained in the hydrogen (to undergo combustion with oxygen or some other later reaction), compared with the input electrical energy.

Crystallisation. Used to separate a dissolved solid from a solution, when the solid is much more soluble in hot solvent than in cold (e.g. copper sulphate from a solution of copper (II) sulphate).; The solution is heated, allowing the solvent to evaporate to leave a saturated solution behind. Test if the solution is saturated by dipping a clean, dry, cold glass rod into the solution.

Low grade sulfide ores are difficult to process due to their composite mineralogy and their fine grained dissemination with gangue minerals. Therefore, fine grinding of such ores becomes essential to liberate valuable minerals. In this research, selective flotation was carried out using two pitched blade turbine impellers with diameters of 6 cm and 7 cm to float copper and nickel.
