  • Flowsheet development for conceptual through to full feasibility studies
  • Access to specialists through a network of known associates from around the world

Approach

Every deposit has specific metallurgical challenges which need to be resolved in order to be able to develop them.  Metallurgical testwork is essential to develop robust and metallurgically efficient process flowsheets. 

SRK investigates the optimum process solutions by:

  • Selecting representative and variability samples of ore for testwork
  • Developing tailor-made test work programs to investigate the mineralogy, metallurgy and associated treatment processes
  • Defining, managing and evaluating all stages of the test work program
  • Developing proven and cost effective process flowsheets as part of the project development

Experience

Recent project examples include:

  • Russian Cu-Au-Fe concentrator – metallurgical study including comminution circuit testwork and design, review of flotation and magnetic separation testwork and development of a flowsheet (laboratory and pilot plant)
  • West African iron ore project – testwork & flowsheet studies for Scoping and Pre-feasibility Studies
  • Colombian gold project – testwork programme design for Feasibility Study
  • Diamond Project in North West Russia – testwork definition, supervision and interpretation
