Solutions obtained from the leaching of malachite in aqueous acetic acid solutions were used in the study. It was determined that the cementation rate increased with increasing solution concentration, temperature and rotating speed, and decreasing solution pH. The reaction rate fits to the first order pseudo homogeneous reaction model and is controlled by diffusion. The activation energy of this process was calculated to be 32.6 kJ/mol.eninfo:eu-repo/semantics/closedAccesscopper cementationleachingmalachiteactivation energyArticle48235536710.5277/ppmp1202032-s2.0-84865423354N/AWOS:000304889400003Q2
