Membrane technology applied to acid mine drainage from copper mining
(2017)
The objective of this study is to evaluate the treatment of high-strength acid mine drainage (AMD) from copper mining by nanofiltration (NF) and reverse osmosis (RO) at pilot scale. The performances of two commercial ...
Treatment of acid mine drainage: Study of sulphate reduction in organic mixtures
(2017)
Permeable reactive barriers (PRB) are a system for the treatment of ground waters used in the decontamination of acid mine drainage. In this technology, the reactive material is placed as a barrier in the subsoil, and the ...
Comparative study of alternative methods for the simultaneous determination of fe+3 and fe+2 in leaching solutions and in acid mine drainages
(PERGAMON-ELSEVIER SCIENCE LTD,, 2005)
Kinetics of copper removal from acidic mine drainage by a liquid emulsion membrane
(PERGAMON-ELSEVIER SCIENCE LTD,, 2005)
Treatment of acidic mine drainage in an adsorption process using calcium silicate modified with fe(iii)
(2017)
Two compounds based on calcium silicate hydrate and modified with Fe(III), using FeCl3 and Fe(OH)(3) as iron sources, were synthesized, characterized and evaluated as adsorbents for removing ionic species from an arsenic ...
Comparative study of alternative methods for the simultaneous determination of fe+3 and fe+2 in leaching solutions and in acid mine drainages
(PERGAMON-ELSEVIER SCIENCE LTD, 2005)
In leaching solutions coming from the hydrometallurgical processing of copper sulphides, it is necessary to determine the concentrations of Fe-total,Fe- Fe+2 and Fe+3. It is known that the 5-sulfosalicylic acid (SSA) forms ...
