| مستخلص: | Papers are presented in the following sections: Introduction and general (9 papers); Comminution (4 papers); Preconcentration (7 papers); Refractory gold processing (10 papers); Bio-oxidation (5 papers); Copper-gold ores (1 paper); Leaching, heap and dump leaching (10 papers); and Environmental management (13 papers). Technology and processes discussed include high-angle conveyors, lead-free fire assaying, vacuum suction of lost gold, tailings treatment, semiautogenous grinding, mill pumps, Knelson and Falcon centrifuges, high-grade tank flotation cells, polymeric flocculants, gravity circuits, identifying preg-robbers, flash roasting, the Activox process, pressure oxidation, autoclave linings, reactive metal piping, oxidative pressure cyanidation, the MinBac process, the Biox process, bacterial oxidation of pyrite and arsenopyrite, bioreactors, agitators, ammonia-cyanide leaching, leach pad liners, oxygen supply, heap stacking, carbon in pulp, guanidine-based resins, selective anion exchange resins, scale inhibition, thickener control, Cyanomet R cyanide recovery, bio-detoxification of spent ore and solutions, treatment of ammonia and nitrates, selenium removal, and waste treatment using sulphate-reducing bacteria, Caro's acid, iron oxide precipitation, artificial wetlands and silver-impregnated activated carbon. Projects in Brazil, Bolivia, Australia, Canada, the USA, Indonesia and South Africa are discussed.
