Static and kinetic acid rock drainage (ARD) tests
Acid - Base Accounting (ABA)

Standard and modified method of determining the acid generating potential of rocks, soil or other material as well as their natural neutralization potential.

Humidity Cell

Simulation of natural weathering on rocks to determine acid generation and release of metals. A typical test includes sequential cycles of dry air flow, moist air flow and flush cycle over a 20-week period.
Special waste leach test
TCLP (SWEP)

Special Waste Extraction Procedure. Standard diagnostic method for metals extraction from rocks under controlled conditions.
Cyanide destruction / degradation studies including bacterial cyanide degradation
Effluent treatment tests
Evaluation of processes for remediation / clean-up of contaminated sites
Continuous effluent neutralization and high density sludge recycle studies
Bacterial culture development and adaptation
Assessment of soil / sediment remediation
Isolation / enumeration of sulphur bacteria and other microbes
High Density Sludge (HDS) mobile demonstration plants
