The recovery of phosphorus (P) from sewage sludge through pyrolysis is one of the most
promising alternatives to alleviate the shortage of P supply in the future. Adding calcium …

The removal of arsenic and heavy metals (HMs) from strongly acidic wastewater by
hydrogen sulfide (H2S) is an efficient method. However, traditional sulfuration reagents …

The effluents from acid plants generated in copper pyrometallurgy contain high
concentrations of sulphates and heavy metals that difficult further reuse of contained water …

In this study, an earth-mimetic method was proposed for the direct removal of As (III) by the
formation of tooeleite, a ferric arsenite sulfate mineral. A series of batch experiments was …

A synergistic combination of chloride and copper powder was proposed as a new method to
reductively remove arsenic from highly-acidic wastewater with high arsenic content (HAWA) …

Large amounts of waste acids with high acidity and arsenic levels are produced during
pyrometallurgy of nonferrous metal sulfide ores, in which the treatment of arsenic remains a …

Acidic rock drainage (ARD) is naturally produced through a series of chemical and
biochemical reactions at abandoned mine sites. ARD containing acidity and a broad range …

A review of literature published in 2008 and early 2009 on research related to the production
of acid mine drainage and/or in the dissolution of minerals as a result of mining, with special …

A coprecipitation of copper (II) and zinc (II) from complex sulfate solutions with natural calcite
was investigated. The main features of the process and mineral forms of incorporation of …
