Sciencemadness Discussion Board Leaching Gold with Lugol

Dec 10, 2012· The method I am attempting is leaching with Lugol's Solution. Reputedly, it is a selective leach and will only dissolve gold, leaving the base metals. Lugol's Solution (iodine, sodium iodide, water) is not the most popular method of leaching, due to the high cost of iodine, but it has been well known as a leach since the late 1800's.

A Method for Leaching or Dissolving Gold from Ores or

solution of gold in these media is always attributed to the formation of the highly reactive nascent chlorine.11 Quite surprisingly, either in the hydro-metallurgical leaching of gold ores by cyanidation or in the aqua regia process used for the recovery of secondary gold

Modelling and simulation of gold ore leaching

Leaching by cyanide solution is widely used as a separation method to recover gold from ores. Different processes can be used to perform this chemical separation. Some rely on Bellec S., Hodouin D., Bazin C., Khalesi M. R. and Duchesne C. Modelling and simulation of gold ore leaching. World Gold Conference 2009, The Southern

Gold Metallurgy and Leaching Process

Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes

How to Use Bleach on Gold Ore to Remove Gold Sciencing

Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride. Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments. Collect the filtered gold chloride solution in a flask.

Gold extraction Wikipedia

The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele, but it was not until the late 19th century, that an industrial process was developed.The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore.The gold could not be extracted from this compound with any
