LIMESTONE NEUTRALISATION OF IRON(II)-RICH ACID WATER …
LIMESTONE NEUTRALISATION OF IRON(II)-RICH ACID WATER …

Lime/limestone neutralisation Both limestone and lime are needed during treatment of acid mine waters. Benefits associated with limestone are its low cost compared to other alkalies (Table 1), automatic dosage control (in the case of a fluidised-bed reactor) as limestone only dissolves at pH-values below 7.5, and limestone is safe to handle.

Effects of acids and alkalis on aquatic life - Lenntech

Limestone can buffer (neutralize) the acidification of freshwater. The effects of acid deposition are much greater on lakes with little buffering capacity. Much of the damage to aquatic life in sensitive areas with this little buffering capacity is a result of ‘acid shock’.

Limestone, reacts with hydronium ions to produce carbon dioxide, ,water,, and calcium ions as described by the reaction equation; CaCO 3 + 2H 3 O + → CO 2 + 3H 2 O + Ca 2+. Because of renewed coal burning upwind of the lake, it starts receiving regular ,acid, precipitation that has a pH of 4.5.

Open limestone channel – Mine Closure
Open limestone channel – Mine Closure

Open limestone channels (OLC), sometimes also called oxic limestone drains (OLD), are simple constructions for acidic mine water treatment. The idea is that as the acidic mine water flows through a channel filled with coarse limestone cobbles, CaCO 3 dissolves and …

Solvay process - Wikipedia
Solvay process - Wikipedia

The ,Solvay process, or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia-soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and ,limestone, (from quarries).
