In recent years, organoclays have become widely used in many industrial applications, and particularly they have been applied as adsorbents for water purification (de Paiva et al., 2008; Zhou et al., ...
Effectiveness of polymers on improving the fluid loss of Bentonite used in geosynthetic clay liners
Effectiveness polymers improving fluid loss Bentonite used geosynthetic clay liners
2012/3/30
Geosynthetic clay liners (GCLs) are generally used in engineering projects due to their low hydraulic conductivity with water. The bentonite component contributes hydration-induced swelling and impart...

development later stages Murray Basin development smectite (bentonite) clays
2012/3/30
This talk will be in two sections – the first part will discuss the development of the Murray Basin from the start of the final marine incursion (Loxton/Parilla Sand) until the present and will discus...
Synthesis and characterisation of hydrotalcite from bauxite residue liquor and magnesium nitrate
Synthesis characterisation hydrotalcite bauxite residue liquor magnesium nitrate
2012/3/30
The extraction of alumina from bauxite by the Bayer process produces a slurry by-product referred to as ‘bauxite residue’ or ‘red mud’. The liquid component of the slurry is highly alkaline and requir...
