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

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.
