Abstract
     Influence of agitation and temperature upon extraction of gold to thiourea solution was studied. Rotating disc electrode technique was used for this purpose. The area of the rotating disc electrode was 0.385 cm2. Critical value of rotations per minute was found to be 300 min-1. Temperature showed to be another important factor effecting the rate of gold dissolution. Activation energy was found to be 99 kJmol-1 for temperature interval from 25oC to 35oC. Decomposition of thiourea and passivation of gold surface by orthorhombic sulphur occurred at higher temperatures.
