In this article,lead-zinc tailing was used as raw material to prepare middle heat clinker.

The burnability of the high tricalcium silicate Portland cement raw meal produced by lead-zinc tailing and shale and property of the resulting clinker were studied in this work.

The effects of water-binder ratio,casting temperature and aluminum powder content on the gas forming behavior,and those of lead-zinc tailing content,cement content and conditioning agents on the compressive strength of the aerated concrete were investigated.

Pot experiment was used to study the effects of four amendments (calcium-magnesium phosphate, sepiolite, calcium carbonate and organic manure) on the growth and heavy metal (Cu, Cd, Pb and Zn) accumulation characters of Juncus effuses grown on the soil contaminated by lead/zinc mine tailings.

A pot experiment was conducted to investigate the potential of Juncus effuses and Eulaliopsis binata for phytoremediation of lead/zinc mine tailings contaminated soil under the adjustment of different mass molar concentrations of EDTA.

Establishment and growth of Lolium multiflorum for phyto-remediation of Pb/Zn tailings;

In order to understand the effects of acid rain and self acidification of Pb/Zn tailings on the phyto toxicity of the open stored tailings,acid leaching tests of Pb/Zn tailings were undertaken for 50 days.
