The Muruntau and the Kumtor gold deposits in the middle Asia Tian-shan.was super-large deposits of thousand ton level.The feature of Muruntau-type gold deposits was which in the carbonaceous clastic rocks.and the ore was quartz stockwork and the stringer vein.The Xinjiang Tian-shan was joined with the miner alization belt which aforementioned deposits in it.In the Xinjiang Tian-shan.the Nanati zone and the southern Tian-shan zone was the most perspective for search for mineds of the Muruntau-type gold deposits.The Saw ayartun deposits in souther Tian-shan was a Muruntau-type gold deoposits.which first finded in China.
Indium is mainly present in dispersed form in nature.How ever,the authors discovered indium enrichment in the study of Cambrian gold deposits,western Qinling Mountains.In the gold ores,indium is generally within the range of 5×10-6～17×10-6,which is enriched to the degree of industrial by-products.Research on the enriched characteristics of dispersed element is of great important significance theoretically and practically.
The best metallogenic setting of the greenstone belts gold at tectonically remobilized belts of the paleocontinental margins.The best metallotectonic framework of greenstone belts gold is characterized by "one zone between two zones".Very important occurence location of gold deposits are ore-controlling structures patterns of ifferent nature and and occurrence.Mineralized charactors of greenstone belts gold deposits divicled three types and seven sub-sypes,base on the auriferous rock formation of greenstone belts and guide the metallotectonic.
Refractory gold ores are the main resources of the development of golden industry for the future,A lot o f studying and developing work have been carried on for the pretreatment of refractory gold ores and subsequent cyanide gold refining in the recent 10 yeras,in which the oxidation roast,hydrometallurgy and microbio oxidation have been applied to the industry.This paper gives a brief view for the present situation and problems of refractory gold ores cyanide gold refining.
