Gold Analysis in Alkaline Cyanide Solutions Atomic GOLD ANALYSIS IN ALKALINE CYANIDE SOLUTIONS A Textbook of Fire Assaying DIBK Extraction The La buffer method works for Au in typical solutions but must be Inquire Now recovering gold using cyanide Recovering gold from cyanide solution is a very old methodGet Price
DiIsobutylKetone DIBK has been commonly used in most mining and allied industries to extract gold from aqueous solutions for analytical purposes In most cases a complexing agent methyl tricapryl ammonium chloride otherwise called aliquat 336 is added to the DIBK to give a 1 volume by volume solution The DIBK containing aliquat 336 is then used to extract gold from aqueous solutions for subsequent analysisGet Price
The cyanide solution is acidified with tydrobro mic acid and bromine water to oxidize the mnovalent gold to the trivalent state The gold is then ed by extracting into a measured volume of methyl isobutyl ketone MIBK The gold concentration is determined by an atomic absorption spectrophotometerGet Price
ume solution The DIBK containing aliquat 336 is then used to extract gold from aqueous solutions for subsequent analysis using Atomic Absorption Spectrophotometry AAS After the AAS analysis the DIBK aliquat solution containing gold is stored as waste since its disposal is often associated with environmental problems The environGet Price
Direct atomic absorption is the most common means for determining gold in alkaline cyanide solutions This choice is dictated by its relatively low cost for single element determinations short analysis time and reasonable accuracy With the exception of Battle Mountain Gold and the Bureau of Mines labs in the methodGet Price
