The efficiency and suitability of these procedures and their corresponding extraction steps for partitioning the heavy metals bound to the solid forms were tested. Metal analysis was carried out by inductively coupled plasma optical emission spectrometer (ICP-OES). The two procedures were examined and showed that there are differences in the bonding forms of the metals to ore and in the properties of the reactants used. Because of these differences, the amount of metals passing through the solution are different in the two procedures.eninfo:eu-repo/semantics/openAccess[No Keyword]Article395198202WOS:0004526556000042-s2.0-8506562621710.46770/AS.2018.05.004Q2Q4
