    Pb(II) adsorption on Tata chromite mine overburden Lenntech

    Low chromite containing overburden is usually dumped as a waste material during mining of chromite ore. A large quantity of such waste is generated in TISCO chromite mines, India. Since this overburden material contains 2046% iron, it can be a potential adsorbent for toxic metal ions present in wastewaters and industrial effluents.
