Mineral Technologies’ work totalled 8000 man hours across various disciplines for design and construction support. Successful commissioning of a two-stage spiral circuit totalling 216 twin start spiral separators was completed in 2006 achieving both concentrate grade and production capacity.

Smart Engineering

The scope of the project required Mineral Technologies to conduct initial onsite testwork to evaluate the capability of spirals to beneficiate the fine iron ore fraction - 1.2mm to 0.075 micron.

Mineral Technologies was selected to provide a technology package including process engineering design and process equipment supply. The package included:

  • Beneficiation process flowsheet design for up to three feed streams
  • Process engineering with process guarantee
  • Mechanical, structural and civil design for the process plant including, feed hopper, trommel screen, tailings and concentrating stacking
  • Preparation of equipment specifications for tender purposes and anaylsis
  • Plant commissioning to prove plant production and performance
  • Operator training
  • Electrical and automation design

Project Highlights

  • In field pilot scale spiral testing
  • Fully integrated processing solution
  • Design of plant including feed hopper, trommel screens, tailings and concentrate stacking
  • Process flexibility to treat blends of up to three feed streams
