The effects and efficiency of each extraction step used in these procedures were examined. Metals analysis was performed by ICP-OES. Due to the differences in the binding forms of the metals existing in the structure of the ore and the different properties of reagents used, the concentrations of the metals were different in the extraction steps of both procedures. When the results were examined, it was found that the metal concentrations passing to the solution in each extraction step of the modified Tessier procedure were much higher than of the revised BCR procedure. Thus, it was concluded that the modified Tessier procedure is more suitable for decomposing metals in malachite ore.eninfo:eu-repo/semantics/openAccess[No Keyword]Article404122126WOS:0005058424000022-s2.0-8507692130510.46770/AS.2019.04.002Q2Q3
