| Popis: | This research was undertaken to study the effect of adding silver nitrate (AgNO 3 ) during leaching of gold ore for Au recovery. Its focus is to obtain the weight of Au in feed and concentrate, the effect of AgNO 3 on Au recovery, theconcentration of AgNO 3 that led to optimum recovery, and the weight of bullion and Au content in bullion. This research was conducted using quantitative descriptive method with experimental technique and the research steps include the following: 1) rock and treatment plant preparation, 2) tests with variable AgNO 3 concentrations, 3) analysis feed and concentrate samples using atomic absorption spectroscopy (AAS), 4) measurement of concentrate density, 5) burning of activated carbon to get the bullion, and 6) weighing bullion and Au content. There was increase Au recovery from 12.57% to 36.15%. On addition of 0 to 4 gram of AgNO 3 , whereby highest recovery was obtained on the addition of 4 g of AgNO 3 concentration to 150 kg of feed. |
