10.1 Precipitation of Barium Sulfate – Pre-Lab Questions

2016-9-9  10.3 Precipitation of Barium Sulfate – Procedure All work should be done in the hood! Safety Notes: Barium is a heavy metal and you should avoid contact with the barium solutions and precipitates as much as possible. If you splash some solution on your hands, wash them immediately. Be sure to dispose of the filtrate and solid properly.

Precipitation with barium salts – Mine Closure

Precipitation with barium salts can be applied for the reduction of sulphate from mine waters to low concentrations. Advantages of barium salt precipitation (INAP 2009, DWA 2013) include e.g.: The process effectively removes sulphate. Some processes generate by-products (such as elemental sulphur or H 2 S) which can potentially be processed to ...
