Research progress on non-cyanide leaching of refractory gold ores
工程科学学报, 2019 With the increasing demand for gold and the decreasing of easily treated gold resources, refractory gold ores, which are characterized by low gold recovery and high cyanide consumptions when subjected to direct cyanide leaching, have gradually become the

Advanced Functional Materials, EarlyView.DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Size dependent gold deportment in the products of copper flotation and methods to increase gold recovery [PDF]
, 2003 Plant survey data has shown that gold recovery through a specific copper concentrator was significantly lower than copper recovery. Size-by-size analysis revealed that this was due to poor recovery of +75 μm and -23 μm gold containing particles. In order
