PRODUCTION OF SILVER RUBLE AND PARTICIPATION OF THE SAINT-PETERSBURG MINING UNIVERSITY IN THE DEVELOPMENT OF MONETARY INDUSTRY OF RUSSIA

Article preview

The article is a continuation of the research on the production of silver rubles and the development of Russian coinage. Graduates of the Saint-Petersburg Mining University contributed to the reputation and history of the Saint-Petersburg Mint as an advanced and high-tech production. The article describes the beginning of the development of silver ruble production, the use of ores from the Nerchinskoye deposit in the Transbaikalia to produce the main raw material in the form of concentrates and a silver alloy. The materials for the study used unique exhibits of the Mining Museum of the Saint-Petersburg Mining University, which are associated with the history of coinage and the Saint-Petersburg Mint. Some samples of lead-silver ores cast billets, and stamped coins were studied to determine the technological features of their manufacture. An analytical study of the features of minting and obtaining the first Russian silver coins according to some data of the royal decrees was carried out. The current level of technology and knowledge, as well as the special equipment of the laboratories of the Saint-Petersburg Mining University, made it possible to re-evaluate the characteristic features of the production of silver coins.

Prospects of biotechnologies application in metallurgy and enrichment

Article preview

In recent years, application of biotechnologies in enrichment processes and processing of metal-containing ores has gained broad development, considering essential advantages of these technologies from the point of view of economic efficiency and ecological safety. Processes with the application the hemolitotrofnykh of acidophile microorganisms of Acidithiobacillus ferrooxidans, At. thiooxidans, Leptospirillum ferrooxidans and others, are of great interest.  This article is devoted to the problem of biocultures application for efficiency improvement of the ore pretreatment technology and extraction of valuable components from metal-containing crude ore. The analysis of the biotechnologies and microorganisms applied at domestic and foreign enterprises is given, alongside with the theoretical bases of ore bioprocessing, research results of oxide and sulphidic metal-containing ores processing technology development, with the application of microorganisms and research results of the mechanism of destructive impact of a certain type bacteria on siliceous ores.

Character determination of fusion mode оf sulphidic material in the gas-jet rotation devise

Article preview

By working out of new technologies for fusion of sulphidic concentrates on matte and hardware registration to them special attention it is necessary to give possibilities of management of oxidation degree of malt in a reactionary zone and uniformity of oxidation process. In this connection development of the oxidation theory and behavior of sulfides in malt is of great importance for designing of fusion devices of sulphidic concentrates and revealing of management possibility of them.

Application of center-run extractors in petrochemistry

Article preview

One of the ways of recovery of metals from oil is considered. It is proposed to carry out the extraction of metals from oils using a separator with centrifugal phase separation. This type of separators can be used not only for extraction of valuable components such as metals from oils, but also for purification of water from oil products, as well as for hydrometallurgical production of non-ferrous metals.
