Abstract

The test of gold-bearing humic substances aimed to find forms of gold in them. The test results enable estimation of gold compound mobility during sedimentation of humic acids. Re-sedimentation of humic acids shows similar properties of gold after dissolving with and without a selective dissolver. The amino-acid analysis of humic acids before and after their interaction with ammonium hydroxide reveals the increased content of amino acids capable to dissolve gold. Stage-wise spin of gold-bearing liquid humic acids at acceleration from 4000g to 233000g and at pH of 11 nullifies gold-bearing particles in solutions and makes the latter homogenous. The authors describe the impact of destructive effects relative to organic compounds on joint sedimentation of gold and humic acids.
