we are leaders in

Mine waste and materials management including:

  • International experience in metalliferous waste rock, tailings and process residue assessment and management.
  • Extensive Australian and SE Asian experience in coal, spoil, rejects and tailings management.
  • Detailed waste rock dump (WRD) and tailings storage facility (TSF) design for rehabilitation using Deswik.CAD and Deswik.LHS.
  • Strategic development of mine waste management options assessment and risk assessment of life-of-mine planning.
  • Waste rock dump and tailings performance evaluation.
  • Integration of waste rock and tailings using co-disposal, co-mingling and paste technology.
  • Experience drilling tailings, rejects and waste rock for installation of monitoring equipment.
  • Waste rock and tailings seepage assessment and investigation.
  • Produce Management Plans for operating mines (e.g. Mine Waste Management Plan).
  • RGS work with Deswik to provide mine planning, waste scheduling and design services using Deswik.CAD, Deswik.Enviro and Deswik.LHS.

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.
