Abstract
<p>The present invention provides a method of extracting gold from pregnant leach solution (PLS) obtained from leaching of gold, comprising the steps of: (a) extracting the PLS with an organic extractant comprising an organic diester and an organic long-chain alcohol to obtain a first organic phase comprising gold; (b) stripping gold from the first organic phase with a first water to obtain a first aqueous raffinate comprising gold and a first depleted organic phase; (c) adding HCl and NaCl into the first aq</p>
