Abstract

The extraction of gold with 336 Alamin and Alkylaniline from hydrochloric acid solutions was studied. Shown that Alamin extracts gold quantitatively in the field of acidity of the aqueuous phase pH=3,0 – СHCl=3,5 M when used as diluents of kerosene and higher carboxylic acids in admixture with paraffin. The time of quantitative extraction of gold: with Alamin – 3 minutes, with Alkylaniline – 5 minutes, regardless of the choice of diluent. The composition of the extracted complex and scheme of  gold extraction process with Alamin was proposed. Extraction of gold with 5%- Alamin-HCA-paraffin can be used for development of a combined extraction -  X-ray fluorescence technique for determination of gold because the resulting solids extracts meet the requirements imposed on emitters samples in X-ray fluorescence analysis. Calibration characteritstic is linear in the range of gold content in the samples emitters 0,006-0,17 wt%.
