We investigated the potential of tailings from phosphate mining, consisting of phlogopite, carbonate minerals calcite and dolomite, and residues of apatite, to serve as a stabilizing agent in the remediation of Pb-contaminated soil in situ or on-site

Charged biopolymers able to adsorb solubilized metal cations instead of precipitating them as inorganic waste provide a sustainable option for conventional lime treatment of acidic metal-bearing effluents. We investigated the adsorption of trivalent

Treatment of acidic mining water (MW) with industrial minerals and alkaline chemicals requires utilisation of unrenewable raw materials and produces disposable inorganic sludges of no further use. We investigated the efficiency of bio-based anionic n

Utilisation of sodium (Na + ) containing alkali in the neutralisation of acidic industrial process waters rich in sulphate (SO 4 2 − ) produces effluents high in sodium sulphate (Na 2 SO 4 ) reluctant to precipitate. Discharge of the saline effluen

We carried out an adsorption experiment to investigate the ability of anionic nanofibrillated cellulose (NFC) to retain metal and SO42- ions from authentic highly acidic (pH 3.2) mining water. Anionic NFC gels of different consistencies (1.1%, 1.4-%

The Pb sorption capacity of apatite ore mine tailings and its potential to act as a remediation agent in a Pb polluted areas were investigated. The tailings, originating from the Siilinjarvi carbonatite complex in Finland, consist mainly of phlogopit

The information on biogeochemistry of silver (Ag) is scarce and mechanisms of Ag uptake by plants are still unclear. We studied the impact of silver sulfate (Ag2SO4) and silver nitrate (AgNO3) on biomass of wheat seedlings, the rhizosphere proteins a
