Abstract Sulphate (SO 4 2−) is a common anion nutrient naturally occurs in water bodies,
and considered not toxic when presented in low concentration. However, the presence of …

Metal sulphates are one of the major contributors to acid mine drainage (AMD) or acid rock
drainage (ARD). AMD occurs by the oxidation of metal sulphides. Sulphides produce …

Acid mine drainage induced by the mining industry causes environmental and economic
issues. Acid mine drainage contains mainly metals such as Fe, Al, Cu, Ca, Mg, Mn and Zn …

Abstract Sulfate (SO 4 2-) is a ubiquitous anion in natural waters. It is not considered toxic,
but it may be detrimental to freshwater species at elevated concentrations. Mining activities …

Blast-furnace slag and metakaolin were geopolymerised, modified with barium or treated
with a combination of these methods in order to obtain an efficient SO 4 2− sorbent for mine …

Removal of sulfate from water is an environmental challenge faced by many industrial
sectors as most existing options are inefficient, costly or unsustainable. The situation is …

Sulfate decontamination has drawn widespread attention due to its harmful effects by broad
human and animal exposure in recent decades. Adsorption is one of the most promising …

Limestones and their modifications from Nordkalk Corporation (Finland) flotation fines (FF)
and filter sand (FS) as potential adsorbents for AMD treatment and wastewater purification …

One of the main challenges in industrial wastewater treatment and recovery is the removal of
sulfate, which usually coexists with Ca 2+ and Mg 2+. The effect of Mg 2+ on sulfate removal …
