Gold(III) extraction and recovery and gold(III)/copper(II) separation .

The recovery of gold entrapped in the micellar pseudo-phase has also been investigated. Different stripping agents have been used, the most efficient of them being a mixture of NaCl and NH3 which allowed the metal to be expelled from the micelle with a yield of 85%. Finally, Au(III)/Cu(II) separation is achieved with DTAC.

Separating gold from impurities is called parting, and was a very difficult thing in antiquity, when strong acids were unknown.

ECO-FRIENDLY Recovery of GOLD and COPPER for the . - pcieerd

Jun 27, 2014 . The use of low-end technologies in crushing and grinding of ores leads to lack of liberation and minimum exposure of gold values which results in inefficient separation and low recoveries of gold values during Cyanidation and/or Amalgamation. Processes. Recovery is only 40 to 50%:. Background.

Ion Exchange Resin vs. Activated Carbon for Gold Recovery - Purolite

copper of activated carbon (Haycarb coconut based), a strong-base (Purolite A194) resin, and medium-base (Purogold S992) gold selective resin was investigated. The ease with which the loaded gold could be eluted from the adsorbent and the ability to effect gold/copper separation via split elution was also compared.
