Abstract
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.
