Ore Sorting
Ore sorting is suitable for several minerals and is capable of maximizing recovery or upgrading the ore. Sorting technology analyzes the atomic properties of particles to identify unique physical and chemical characteristics and separates them by utilizing jets of compressed air. Halyard works alongside TOMRA Sorting to provide turnkey modular solutions that allow clients to realize the economic benefits of XRT/XRF, laser, or colour sensor-based sorting in any climate.
Benefits of Optical Sorting:
- Decreases variability
- Powerful methods of pre-concentration or waste rejection
- Occurs early in the comminution process which reduces downstream capital expenditure
- Decreases the use of consumables (water or electricity) per unit of metal produced
- Feed grade to the plant remains high
- Flotation and leaching recoveries are generally increased due to the higher head grade
- Opportunity to unlock value buried in stockpiles
Bulk Sorting
As it is becoming more difficult to extract mineralized ore from low-grade deposits. Removing barren material earlier in the process can bring significant savings to mining operations. It also reduces the mine’s environmental footprint by lowering energy consumption, greenhouse gas emissions, and overall water losses.
Benefits of Bulk Sorting:
- Eliminates barren material early in the process
- Increases the grade of the ore in the next stage of processing
- Avoids feeding the plant with material that will cost more to process than its contained value
- More value with less impact, improving resource efficiency and sustainability
- Reduces the generation of tailings product
- In existing operations, production rate can be increased due to the increase in feed grade
