The article discusses the issues of processing slag of copper production using devices that model ideal mixing. It has been shown that the use of this type of apparatus increases the efficiency of physical and chemical processes and significantly reduces the copper content in dump slags. It has been found that the process of reduction of ferric iron oxide by the clinker in the initial period takes place in the kinetic mode. After reducing the concentration of magnetite (3-5%) in the slag, the process of reducing it passes into the diffusion region, that is, restoring the excess content of ferric iron in iron silicate melts takes a short period of time during which the process can be carried out, without significantly delaying the operation time of the main industrial equipment. The optimal slag magnetite reducing agent is determined to be zinc production waste
The current paper highlights theBaselI, Basel II & Basel III requirements on capital adequacy and liquidity of commercial banks. In the paper, Basel II structure, methods of loan risk assessment, coefficients of loan risk assessment, credit risk measurement for counterparty banks are discussed. Moreover, assessments of Basel III on bank chances against crisis driven from financial and economic crunches, risk management, performance quality and bank transparency improvement measures are presented. At the end, the author gives his conclusions on the essence and necessity of new regulatory standards of the Basel Committee on bank’s supervision in the structure of the supervision of credit institutions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
