On the use of lignin-based biopolymer in improving gold

2016-4-1  Lead nitrate has been used as additive in gold processing plants for more than 60 years to improve gold recovery and leaching kinetics. It was reported by Guo et al. that pretreatments of gold ore by lead nitrate reduce the extent of gold surface coating by silver, iron and sulfur ( Guo et al., 2004,Deschenes et al., 1998 ).

2018-1-15  Cyanide gold leaching was the most efficient when the 30% chromium media was used during the grinding of the ore for both pyrite and arsenopyrite. In addition, in the presence of pyrite, due to the lower galvanic current between pyrite and grinding media in comparison with arsenopyrite, the amount of iron hydroxide was lower, and thus more free
