By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.

2017-9-7 Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.

2019-12-26 Gold leaching by hypochlorite has been studied by Baghalha and Yen et al. , who suggest that an oxidative pretreatment should be adopted when processing refractory ore (Yen et al. 1990). Gold leaching in hypohalide media is highly dependent on the acidity and generates chlorine gas (Lalancette 2009; Lalancette et al. 2015a).
