Synergistic extraction of gold from the refractory gold ...

2017-7-1  Under the conditions, the extraction rate of gold was 68.55%. What's more, in order to prove that the ultrasound assisted extraction has an advantage over the conventional extraction, we carried out conventional extraction under the same conditions. However, the extraction rate of gold is only 45.8% after 6 h. Therefore, ultrasound not only increases the extraction rate, but also shortens the extraction

Stepwise extraction of gold and silver from refractory ...

2020-6-1  The extraction of arsenic linearly increases from 14.24% to 31.18% with increasing temperature from 20 to 60 °C. 40 °C was chosen for extraction of gold and silver from the calcine based on these results. The effect of leaching time on the extraction of gold, silver and arsenic in thiourea solutions was presented in Fig. 3 (f). The result shows that the extraction of gold and silver increases gradually with the extension of leaching time and keeps steady after 2 h, whereas the extraction ...
