Solvent extraction of gold from chloride solution Book Gold History of Use Mining Prospecting Assay Production

Gold extraction by the individual extractants was also examined The extraction mechanisms were studied at an aqueous feed to organic solvent ratio of 10 1 Gold extracted into the organic phases was analyzed by flame atomic absorption spectrophotometry The slope analysis indicates the independence of acidity on gold extraction for both DIBK Gold was produced in the southern Appalachian region as early as and perhaps as early as in southern California The discovery of gold at Sutter s Mill in California sparked the gold rush of 50 and hundreds of mining camps sprang to life as new deposits were discovered Gold production increased rapidly
