THE COUNCIL FOR INDUSTRIAL &
SCIENTIFIC RESEARCH PILOT PLANT – GYPSLIM PLANT |
|
 |
The Gypslim Plant (operational since 5 March
2008) which uses the Gypslim process (patented, designed
and operated by the CSIR) to produce “Industrial” quality
water at a processing rate of one cubic metre per hour.

|
|
THE SAVMIN PILOT PLANT |
|
 |
The SAVMIN Plant (operational since 5 April
2008) uses the SAVMIN methodology (patented by Mintek and
operated by Atomaer RSA (Pty) Ltd) to treat 4 cubic metres of
AMD per hour to “industrial” quality standards.

THE BY-PRODUCT RECOVERY PLANT |
|
 |
The By-Product Recovery Plant (operational
since 10 March 2008 and designed, engineered and operated by the
CSIR, Key Structure Holdings and Sulphidetech) which processes
and isolates by-products produced by the SAVMIN and Gypslim
water treatment processes.
