摘要
FIELD: metallurgy.;SUBSTANCE: nano particles of gold are used in perfume, cosmetic and jewel industries, also for treatment and diagnostics of diseases. The procedure for production of nano particles of gold consists in reduction of precursors of gold contained in solution using an extract of tea leaves as reducer. Solution containing precursors of gold is made of iron ore stock by ion flotation of iron ore stock. Further, produced concentrate is dissolved in aqua Regis and ions of gold are flotation extracted with surface-active substances into extract. Upon flotation extraction they are concentrated.;EFFECT: expanded set of precursors and nano particles of gold produced from them, namely, production of nano particles of hybrids of nano particles of gold out of iron ore stock.;1 ex
