The feasibility to recover thegoldpresent in alluvial material, by means of achlorination process,using chlorineas a reactive agent, has been studied. The influence of temperature and reaction time was studied through changes in the reactant solid. The techniquesusedto characterize the mineral samples and the reaction residues were stereomicroscopy, X-ray diffraction, X-ray fluorescence and scanning …

The Millerprocessuses gaseouschlorinetoextractimpurities whengoldis at melting point; impurities separate into a layer on the surface of the molten purifiedgold. The Millerprocessis rapid and simple, but it producesgoldof only about 99.5 percent purity. The Wohlwillprocessincreases purity to about 99.99 percent by electrolysis.
Goldcan be leached from stone through alkaline or acidic-based products, including halogens, such aschlorine, iodine and bromine. Halogens are reactive, non-metal elements with seven electrons in their outer shell which allow them to easily combine with other elements. Theuseofchlorine…
