(German Mongolian Institute for Resouce and Technology, 2019-05-07) Sukhbaatar.B; Altangerel.L; Dorjsundui.G
In this thesis we deal with modeling and simulating the copper column leaching. The ore with 2.22% copper grade used in this study. Chalcopyrite (CuFeS2) was main mineral in the test sample. Pyrite (FeS2) was determined as the main gauge mineral of the sample. Three experiments produced with different flow rates which were 5.46l/h/m2, 10.25l/h/m2 and 16.4l/h/m2 with 3g/l sulfuric acid concentration (H2SO4) on column. Thus experiments were continued for 15 days. Thirty experiments produced with different acid concentrations for f ind right acid concentration for heap leaching. Comprehensive computational fluid dynamic (CFD) ’virtual 3D heap’ was used as main model in the modeling and simulation.
Supply Chain Finance in Mongolia
(German Mongolian Institute for Resouce and Technology, 2022-05-16) Khongorzul Bayarsaikhan; Altangerel.L; Bat-Uul.N
Previously, supply chain research focused on integrating products/services and information flows while ignoring financial considerations. In today’s highly competitive and fast-changing corporate climate, where the organization of all resources is important, creating an effective supply chain is essential and its finance is getting more crucial.
