THE CHLORINATION PROCESS.

Gold extraction by chlorination using a pyrometallurgical process

The feasibility to recover the gold present in alluvial material, by means of a chlorination process, using chlorine as a reactive agent, has been studied. The influence of temperature and reaction time was studied through changes in the reactant solid. The techniques used to characterize the mineral samples and the reaction residues were stereomicroscopy, X-ray diffraction, X-ray fluorescence ...

The Chlorination of Water

Chlorine is most readily available in the form of chloride of lime (bleaching powder), which can readily be obtained commercially. This, if freshly made, should contain 33 per cent, of free or active chlorine. It loses its efficacy on keeping, especially during hot weather; but this loss may be retarded by the addition of 25 per cent, of quicklime. Samples of the bleaching powder used should be...

Salt Chlorination

Millions of people worldwide enjoy swimming pool activities every year. Traditionally, chlorine-containing chemicals have been used as the sanitizing agent. Some chlorine containing chemicals used include chlorine gas, sodium hypochlorite, calcium hypochlorite, lithium hypochlorite, and chlorinated isocyanurates. These chemicals enter the pool as a concentrated solution, or in the form of hypoc...
