Many gold ores in practice behave according to this reaction and the problems involved in the extraction of the gold are more mechanical than chemical. Many others, however, present an assortment of chemical problems depending on the various constituents in the ores.
The chemistry of gold extraction by John O. Marsden, 2006, Society for Mining, Metallurgy, and Exploration edition, in English - 2nd ed.
Pure gold is easily cut with a knife. Few elements react with gold under normal conditions and so most gold is recovered as small flakes of the pure element. Gold is a very good conductor and is often used to plate electrical contacts since it resists corrosion so well. It also is a good reflector of heat-carrying infra-red radiation.
It bridges the gap between research and industry by emphasizing the practical applications of chemical principles and techniques. Includes in-depth discussions of process selection, principle of gold hydrometallury, oxidative pretreatment, leaching, solution purification, recover, surface chemical methods, refining, and effluent treatment.
Gold is an element whose unique properties are strongly influenced by relativistic effects. A large body of appropriate calculations now exists and its main conclusions are summarized in this critical review. The present paper completes the recent reviews by Pyykkö (2004, 2005) (529 references). Gold - Chemistry, Materials and Catalysis

Depending on whether gold can be selectively recovered from complex alkaline sulfide solutions by electrowinning, gaseous precipitation, chemical precipitation, cementation, solvent extraction, and ion exchange (Anderson and Twidwell, 2008, Anderson, 2012, Luo et al., 2006), ASL could have a good capacity for gold extraction, …
Functionalization of gold nanoparticles is crucial for the effective utilization of these materials in health-related applications. Health-related applications of gold nanoparticles rely on the physical and chemical reactions between molecules and gold nanoparticles. Surface chemistry can precisely …

The noble character of gold is a consequence of its low oxidation potential. The value of its electrochemical potential E o (reduction-oxidation or redox potential) is the lowest of any metal [].This means that gold in any cationic form, the common ionic state for a metallic element, will accept electrons from virtually any source (reducing agents) to …
We investigated how surface chemistry influences the interaction between gold nanorods (AuNRs) and cell membranes and the subsequent cytotoxicity arising from them in a serum-free cell culture system. Our results showed that the AuNRs coated with cetyl trimethylammonium bromide (CTAB) molecules can …
The chemistry of gold dissolution in alkaline cyanide solution has continually received attention and new rate equations expressing the gold leaching are still developed. The effect of leaching parameters on gold cyanidation is studied in this work in order to optimize the leaching process. A gold leaching model, based on
The gold ore of Shandong Gold Mining (Xinhui) was a refractory ore, which contained multi metallic sulfides (ZnS and PbS etc.) and carbonaceous. The gold ore concentrate came into leaching process … Expand

With environmental problems and a shortage of resources, it is urgent to recover gold from electronic waste (e-waste). Meanwhile, it is necessary to explore the relationships between the structures and extraction performances of ionic liquids (ILs) to further improve the extraction capacities of ILs for gold. Herein, three pyrrolidinium-based ILs with various N …

As a result, copper and silver were dissolved in it, and considering chemical features, gold remained in solid objects. To dissolve gold, the leached sludge is leached into the mixture of 1 mole nitric acid and 3 moles choric acid. More than 99.92 percent of the dissolved gold with some impurities entered the aqueous phase.
