Newbery-Vautin chlorination process - Wikipedia, the free encyclopedia. The Newbery-Vautin chlorination process is a process to extract gold from its ore using chlorination developed by James Cosmo Newbery and Claude Vautin.
DST's chlorination process uses sodium hypochlorite with a catalytic amount of sodium hypobromite in acidic conditions to put the gold into solution. Contact time is short, and the process operates in a closed loop. All chemicals are recycled within the circuit and, sea water is also suitable where available.
What Is The Chlorination Process For Gold Mining. gold chlorination process - saigroupofhospitals. Removing the gold-bearing rock from the ground is just the first step.
Alkaline chlorination is a relatively simple process in which cyanide leachate is treated in a nine-step procedure. During alkaline chlorination, cyanogen (CNCL) is formed and hydrolyzed to the cyanide (CNO) at an alkaline pH:
Gold extraction by chlorination using a pyrometallurgical process 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 and scanning electronic microscopy.
Process Flow Gold Mining Gold mining was first carried out in alluvial areas, namely in watersheds that have a mineral content of the ore deposits of gold, where gold is mined by a very simple way by using the tools of a pan.
