WebRecycling Potential of Waste Di-Isobutyl-Ketone (DIBK) and Recovery of Residual Gold * W. K. Buah, G. Ofori-Sarpong and A. K. Banson Abstract Di-Isobutyl-Ketone (DIBK) has … WebA solvent extraction method using diisobutyle ketone (DIBK) is designed for the accurate and precise estimation of very low concentrations of gold in rocks, ores and other geological samples....
WebGold is then concentrated by extracting into methyl isobutyl ketone prior to determination by atomic absorption. By either method concentrations as low as 50 parts per billion of gold can be determined in a 15-gram sample. Part or all of this report is presented in Portable Document Format (PDF). WebIt was found that gold extraction with quaternary amines was possible but stripping was difficult. A method was elaborated for the determination of the content of gold in geological samples by atomic absorption spectrophotometry (AAS) in combination with the fire assay method. The lower detectable limit for gold was 0.005 g/t.
