Herculano – 3.5mpta Beneficiation Plant

Project highlights

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

Superior technology

The scope of the project required Mineral Technologies to conduct initial on-site 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 comprising process engineering design and process equipment supply. The package included:

• Beneficiation process flowsheet design for up to three feed streams
• Beneficiation process flowsheet
• Process engineer 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 analysis
• Plant commissioning to prove plant production and performance
• Operator training
• Electrical and automation design

Mineral Technologies’ work totaled 8,000 man-hours across various disciplines for design and construction support.

Successful commissioning of a two-stage spiral circuit totaling 216 twin-start spiral separators was completed in 2006 achieving both concentrate grade and production capacity.
