Bavarder sur InternetGold mining is the extraction of gold by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. The expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of m

Bavarder sur Internet2015.8.6 Cyanide (CN –) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H 2 O) to form a gold cyanide complex (Na. [Au (CN) 2] ) and sodium hydroxide (NaOH). The chemical reaction dubbed the “Elsner Equation”, named after its discoverer, is shown below:

Bavarder sur InternetGold typically occurs at very low concentrations in ores – less than 10 g/ton. The most used process for gold extraction is hydrometallurgical recovery (gold cyanidation), which involves a “leaching” step during which the gold is dissolved in an aqueous medium, followed by the separation of the gold bearing solution from the residues.
