During the detailed engineering phase of the project, consideration would be given to using new flotation technology that is currently undergoing full scale testing.
I don't know what this is, but it is interesting to read how they envisioned improving the project from the pre-feasibility stage. I'm not sure whether these measures were incorporated.
- Further improvements to the process design based on additional metallurgical test work, for example:
- optimizing primary and secondary grind size -- thus reducing grinding circuit size and power;
- optimizing rougher and cleaner flotation circuits -- thus reducing both size and number of flotation cells;
- optimizing concentrate grades;
- optimizing solid/liquid separation -- thus reducing size of thickeners and filters.
- Optimize tailings deposition method;
- Optimization of mill location;
- Inclusion of revenue from rhenium;
- Increasing the overall resources of the deposit;
- Conversion of Inferred Resources into Measured and Indicated Resources; and
- Sharing of infrastructure development costs and power with neighbouring potential producers and other stakeholders.
