    Those listed below or the equivalent:
  • Determine the mass of a substance.
  • Recover precious metals from a lead button by means of the cupellation process.
  • Science, mathematics and communications at ABET 4 level.
  • Relevant health, safety. and environmental standards
  • Computer Literacy 

  • UNIT STANDARD RANGE 
    This process is applicable to the platinum mining industry and it applies to prills obtained from the low temperature cupellation stage of the fire assay process.
