A systematic review of sustainable gold extraction from raw ores
The aim of this paper is to present a systematic review of the mineral processing of gold ores, with special focus on alternative leaching reagents to cyanide In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is understanding the mineralogy in order to optimise flowsheet Gold processing 101 Mining Magazine

Green synthesis of gold nanoparticles using an antiepileptic plant
In fact, the recent report on aqueous extract of M. oleifera leaves assisted gold nanoparticles synthesis revealed that it has higher IC 50 value (60 μg mL −1) than our system indicating the effectiveness of our proposed system in free radical scavenging activity. 20 The attachment of the plant component in the green nanoparticle might be in 2001 at Laizhou Gold Processing Plant in Shandong Province with a capacity of 100 t/d, adopting BacTech technology. The largest was built in 2007 in Guizhou Jinfeng with a capacity of 750 t/d, utilizing BIOX. TM. technology.

Full article: Green synthesis of gold nanoparticles using plant
Increasing the biocomptability remains one of the main research milestones in the gold nanoparticles synthesis. This approach warranted the use of polymeric coatings such as polypyrrole which also imparts additional photothermal plus electro-responsive properties to the nanoparticles [Citation 1, Citation 14, Citation 15].Advanced green method for the In the context of its processing, gold deposits are typically classified, for the purposes of simplification, as: 1) free milling, and 2) refractory ores (including complex and carbonaceous). Based on their mineralogical characteristics and their mineral processing techniques required to liberate them, however, gold ores can be classified A systematic review of sustainable gold extraction from raw
