Leaching of an oxide gold ore with chloride/hypochlorite
The leaching rate of gold was 75% at :1 ratio of chlorine and hypochlorite and increased to 81% with adding 1 a chloride/hypochlorite leaching process was performed for zinc plant residues.

How to Use Bleach on Gold Ore to Remove Gold | Sciencing
#0183;#32;3. Conclusions. The information in Table has been captured from the chapters in this book. It is not intended to be more than a summary reference to get a flavor of the processes that operating gold plants have implemented to overcome the issues pertaining to their particular ore mineralogy and water chemistry, and the many other sitespecific factors that come into play.
Other chemicals have been used to leach gold, and they include bromine, chlorine, and thiourea. There has also been a lot of experimentation with various biological media for recovering gold from ores, but no one has come up with a more cost effective and productive method than leaching with cyanide.
#0183;#32;Roasting and chlorine leaching of goldbearing refractory concentrate: The oxidized material is treated by leaching with brine. After gold adsorption/reduction onto The cost of this process is about 60 per ton of material treated. The estimated total plant cost is about 9 million, assuming a straight line
#0183;#32;Chlorine, bromine and iodine were measured using masses of 35, 79 and 127, respectively. Since I has only one stable isotope, m / z = 127 was scanned for its determination. There are two stable isotopes for Cl and Br; however, 37 Cl and 81 Br were not selected because of big interferences from 36 Ar 1 H on counting 37 Cl and 40 Ar 40 Ar 1 H on counting 81 Br.
gold leaching with chlorine plant. How to Leach Gold Ore With Chlorination Sciencing. Apr 25, 2017#183; How to Leach Gold Ore With Chlorination The use of chlorine is both the cheapest and most plentiful method for leaching gold. When you mix sodium chloride and hydrochloric acid together,
#0183;#32;Now we are looking for investors to invest in our new project of Small Gold Cyanidation plant that costs about 350,. The plant will be able to produce 2535kg of gold per month.
STUDY OF GOLD LEACHING WITH BROMINE chlorine and bromine leaching were More recent development of a thiosulfateleaching plant at Barrick Gold''s Goldstrike operation has alluded to
Leaching Gold With Chlorine. The loaded resin was first carbonized in a muffle furnace, then dissolved in aqua regia, diluted with deionized water, and analyzed by atomic absorption lts and discussion chlorine leaching table 3 shows the typical results of the chlorine leaching of gold from the goldbearing sulphide concentrate and its calcine.
Gold can be leached from stone through alkaline or acidicbased products, including halogens, such as chlorine, iodine and bromine. Halogens are reactive, nonmetal elements with seven electrons in their outer shell which allow them to easily combine with other elements. The use of chlorine
#0183;#32;As Reaction shows, chlorine, in presence of chloride ions, readily dissolves elemental gold to gold(III)chloro complex, [AuCl 4], provided the pH is less than 2 (Finkelstein et al., 1966). (1) 2Au + 3Cl 2 + 2Cl 2[AuCl 4] The rate of dissolution of gold by chlorine is much faster than that by cyanide (Filmer et al., 1984).
first chlorine mill gold home gold seperation from ore using chlorine. first chlorine mill . Gold Refining Gold mines process ore using
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
Chloridehypochlorite oxidation and leaching of refractory sulfide gold concentrate 63 Fig. 1. The Pourbaix diagram of FeS at [Fe] = 10 4 M, [S] = 10 M and 25 C (the chlorine species regions are also marked) (Marsden and House, 2005) Fig. 2.
Gold is an almost nonreactive metal, but halogens chlorine, bromine, fluorine and iodine can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine
feed material was leached in 6 M HCl, with chlorine continuously sparged into the leach reactor. After leaching, the solid residue was filtered from the goldcontaining solution. A summary of the pilotplant leaching results is shown in Table II. Because of its high gold content, the Pe#241;oles feed material yielded very little residue.
