Au recovery was calculated based on the initial gold content in the scrap and the kinetics was determined measuring the time dependent release of gold at predetermine intervals (2, 4, 6, 10 and 14 min) under the influence of oxidative parameters. Recovery of Au was optimized using response surface methodology and a second order mathematical model was developed. The stone composition and ...
