we are leaders in

environmental geochemistry and acid and metalliferous drainage assessments:

  • Integration of geochemistry into mine planning and mine closure.
  • Mine waste geochemical characterisation using laboratory static and kinetic testing.
  • Mine waste field trial design and implementation (field barrel leach tests, test piles and cover trials).
  • Geochemical and physical sampling and analytical plans.
  • Hydro-geochemical modelling using PHREEQC and Geochemist’s Workbench.
  • Acid and Metalliferous drainage (AMD) and salinity investigations including remediation options.
  • Contaminated land assessment.
  • Acid sulfate soils (ASS) assessment.
  • Preparation of detailed Site Investigations (SI) and Remediation Action Plans (RAP).
  • Spontaneous combustion management plans.
  • Mine waste management plans for waste facilities.
  • Risk assessment workshops and presentation of short courses.
  • Expert witness and Senior Review.

RGS geochemistry and physical testing laboratory

RGS operates its own state-of-the-art laboratory service in Brisbane ensuring the highest quality assurance/ quality control (QA/QC). The RGS laboratory is compatible to facilitate a range of geochemical and physical test methodologies. Some of the tests regularly undertaken by RGS include:

  • Sample preparation.
  • Kinetic leach testing (including  AMIRA columns through to and sophisticated large custom columns).
  • Static leach testing.
  • Metals and metalloid concentration by handheld X-ray Fluorescence (XRF) spectroscopy.
  • Paste pH and EC.
  • Water quality testing using multiparameter probe (TPSFLT 90 multimeter) for pH, EC, TDS, Eh, DO, temperature and turbidity.
  • Particle size distribution (including hydrometer).
  • Textural analysis.
  • Emerson class tests.
  • Inquire about customised testing.

Handheld portable XRF

RGS owns and is is fully licenced to operate a  portable handheld X-ray fluorescence (XRF) spectrometer.

Field kinetic test experiments and

RGS regularly design, construct and implement in-field kinetic leach tests and field trials.
