    Kinetic aspects of malachite deposition on marble from copper lactate solutions by Gogol, Daniil B., Rozhkovoy, Ivan E., Sadyrbekov, Danyar T., Aldabergenova, Saule K., Makasheva, Astra M.

    Published 2023-02-01
    “…IR spectra of sediments show good agreement with natural samples of malachite and azurite (Spassk deposit, Central Kazakhstan). The results show the possibility of using organic complexing agents for intensifying the processes of secondary mineral formation of copper carbonate minerals (malachite and azurite) to prevent the dissipation of heavy metal ions in soluble forms from poor deposits and dumps during their remediation.…”
