May 14, 2013 Nearly all gold-mining companies use this toxic gold leaching process to sequester the precious metal. The elimination of cyanide from the gold industry is of the utmost importance environmentally, said Sir Fraser Stoddart , the Board of Trustees Professor of Chemistry in the Weinberg College of Arts and Sciences . The effect of pH value on gold extraction for various ore types is shown in Figure 28.4. Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes pH 9.510.0, whereas for some carbonaceous ores, pH value has no apparent effect. However, the outcome will vary depending on the ...

Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold. In a two-step mode, gold extraction from the precipitate was 10% higher and the content of elemental sulfur was two times lower than in a one-step process. MeSH terms Ferric Compounds / chemistry*
