May 20, 2013· Extracting gold from ore is a poisonous business. The most common method is cyanide leaching, where cyanide salts in solution are used to suck the gold out from its ore. You get gold.
Get PriceHow to Leach Gold Ore With Chlorination | SciencingGold 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 s leaching gold ore with chlorine

Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process.
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.
Mar 15, 2018· It is known since the end of the XIX century that bromine is an excellent leaching reagent for gold but the research concerning its potential application as an alternative reagent has been relatively despised, mainly because elemental bromine is hazardous and extremely difficult to store or transport in safe conditions.
Alternates to gold recovery by cyanide leaching 123pregnant solution. He suggested that the bromine process had the potentialto be a good and economic alternate to the cyanide LeachingThiourea is another reagent capable of extracting gold and is less toxic thancyanide [4,6].
Apr 25, 2017· 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 is both the cheapest and ...
Abstract. Gold extraction, recovery and economics for two refractory concentrates were investigated using cyanide and bromine reagents. Gold extractions for cyanide leaching (24–48 hours) and bromine leaching (six hours) were the same and ranged from 94 to 96%.
Apr 30, 2018· The tailings from the process are inert from toxic substances, free of sulfide, and do not produce acid leach, making it an extremely environmentally safe process. It requires only a brief contact time of about one hour to give high gold recovery. DST set up a demonstration plant at Thetford Mines in Quebec, Canada, in 2013.
After leaching the gold out of the ore with 35 the solvent which contains free bromine, the precious metal is precipitated by any of the wellknown methods, such as by addition of zinc dust or ferrous sulfate. The reactions which result in the elimination of the gold also cause reduction of the free bromine .
Halide Leaching The group of chemicals known as halides is composed of the elements fluorine, chlorine, bromine, and iodine. We will ignore fluorine because it does not dissolve gold.
May 14, 2013· The new process also can be used to extract gold from consumer electronic waste. Current methods for gold recovery involve the use of highly poisonous cyanides, often leading to contamination of the environment. Nearly all goldmining companies use this toxic gold leaching process to sequester the precious metal.
Jan 21, 2019· This was a new one on me, and since I cover gold processing in my class, I spent a bit of time checking up on it. It looks like what you are talking about is this: USB2 Compounds and methods to isolate gold The method they actually used a...
What is the Effect of Aeration on Gold and Silver Leaching. Another of the prime requisites of successful cyanidation is free oxygen. Pure oxygen is too expensive to use, instead atmospheric air is the customary source of the required oxygen gas. Some interesting experiments have been conducted using Ozone but the practice has not been adopted commercially on account of the cost in the gold ...
4. HALIDE LEACHING Chlorine, bromine and iodine are wellknown lixiviants for leaching gold, as recently reviewed by Tran et al. (2001). Chlorination was applied extensively in the late 19th century before the introduction of the cyanidation process. Bromine/bromide for leaching gold from ores was reported as early as 1846.
For this propose, the gold leaching reagents are described and discussed in terms of their environmental and economical points of view. As result of this comparison, thiourea stands out as the most promising alternative gold leaching reagent to cyanide. ... (2007) BromineChemical Leaching of Gold. World Placer Journal, 7, 79.
PDF | This paper presents experimental evidence that supports the use of bromine/bromide as a potential alternative to conventional cyanidation for gold leaching. The study evaluated a bromine ...
the halogens, bromine has received increased attention in a number of investigations [27]. Using systems halide/Halogen gold mining has been documented in several studies. The use of bromine in the leaching of gold ores was first patented by Sheaffer. This process was modified by Himman,

A process for the hydrometallurgical recovery of gold from materials containing gold comprising leaching the materials with a lixiviant containing iodine. To a solution concentrated with natural salts is added elemental iodine until saturated, whereupon mineral sulfides in the ore zone charged with this solution react with the iodine to form iodide.
Apr 24, 2017· 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. ...
