Mining activities are notorious for their environmental impact, with acid mine drainage (AMD)
being among the most significant issues. Specifically, AMD has recently been a topical issue …

A reactive transport model based on one-dimensional transport and equilibrium chemistry is
applied to synoptic data from an acid mine drainage stream. Model inputs include …

This paper describes pilot scale tests of a novel process for the neutralisation of acidic mine
water. Leachate from a waste coal dump was neutralised with limestone, and iron …

Mean contents of trace elements and ash in channel, bench-column, and dump samples of
the abandoned Bon Air coal (Lower Pennsylvanian) in Franklin County, Tennessee are …

This study investigated the potential for utilizing six treatment agents (two limestones, sand,
starfish, black shale, and concrete as treatment agents for acid mine drainage (AMD) …

O problema da drenagem ácida, abrange todas as atividades associadas com os efeitos
ambientais ocorridos devido a oxidação dos sulfetos como resultado doe exercício das …

ABSTRACT The eMalahleni Water Reclamation Plant, established as a joint initiative
between Anglo Coal South Africa and BHP Billiton Energy Coal South Africa, treats polluted …

Prior to limestone neutralization of acid water, ferrous iron needs to be oxidized to prevent
downstream oxidation and the formation of acid. This study assessed the effect of various …

Traditionally acid mine water is neutralised with lime. Limestone is a cheaper alternative for
such applications. A case study showed that limestone can be used effectively to replace …

This study investigated Fe (II) oxidation during acid mine drainage (AMD) neutralization
using CaCO3 in a pilot-scale Sequencing Batch Reactor (SBR) of hydraulic retention time …
