ES Analytical

Global leaders in rapid test technologies
ES Analytical is the global leader in rapid test technologies for predicting geochemical behaviour and risk associated with waste rock, ore and tailings. Building on extensive world-wide experience in research and development since 1993, we offer a series of industry recognised standard and non-standard laboratory tests, data validation and interpretation options, designed specifically to provide high quality data to address key regulatory, planning, closure and rehabilitation risks related to reactive geological materials and water quality impacts.
ES Analytical Testwork Procedures

Geochemical Assessments

ES Analytical has global experience with geochemical assessments investigating AMD/ARD risk associated with waste rock, tailings and ore concentrates at iron ore, base metal, precious metal, tin, tungsten, molybdenum, vanadium, rare earth elements, graphite, uranium, mineral sands and coal deposits.

We can assist with planning, sampling, testwork procedures, analyte selection and reporting to address the key regulatory, planning, closure and rehabilitation risks and water quality impacts.

Static Geochemistry

ES Analytical offers a range of static geochemical testwork programs and procedures to predict acid, metal and salinity risks in waste rock, ore and tailings. We can assist in the development of site appropriate static geochemical testwork programs, including sample selection, testwork procedures, analyte selection and reporting.
  • Acid-base accounting (ABA)
  • Net acid generation (NAG)
  • Acid buffering characteristic curves (ABCC)
  • Sulfur / Carbon speciation
  • Acid & Metalliferous Drainage (AMD/ARD) assessments (AMDact).
  • Acid Sulfate Soil (ASS) assessments
