文摘The paper deals with interaction of gold-organic matter in these aspects:(i) leaching of gold from rock samples by water solutions containing organic acids or crude oil;(ii) extraction of gold from water solutions by crude oil and distribution of gold in group components of crude oil;(iii) mobilization and transportation of gold with generation and migration of petroleum of oil shales;(iv) kinetics of the reduction of Au^(3+) to Au^0 by bitumen.The results show that organic matter may play an important role in formation of some sedimentary-reworked gold ore deposits by promoting leaching,migration,reduction and precipitation of gold.
