Smart Engineering

The project is a two-stage spiral plant for beneficiation of fine iron ore -1.0mm to 0.075mm at a feed rate of 205 t/h. The scope required Mineral Technologies to conduct onsite testwork and to evaluate the capability of spirals for the beneficiation of fine iron ore. On acceptance of the testwork results Mineral Technologies was selected as the preferred supplier of separation equipment and an EPCM contract.

The final contract scope of supply included:

• Beneficiation process flow-sheet design

• Process engineering with process guarantee

• Mechanical, structural and civil design for the process plant including tailings and concentrating stacking

• Preparation of equipment specifications for tender purposes

• Procurement

• Erection using third party contractors

• Plant commissioning to prove plant production and performance

• Operator training

Successful commissioning of a two-stage spiral circuit totalling 96 twin start spiral separators was completed in September 2004 with both concentrate grade and production capacity achieved.
