摘要

The development of complex low-grade mineral deposits is becoming an increasingly important target for resource companies. These deposits often present marginal economic opportunities, which are highly dependent on the development of low-cost and efficient processing strategies and the utilisation of by-products to become a viable development target. For exploration-focused companies this presents a critical investment decision stage early in project development on whether to pursue potentially expensive resource definition or look for other targets. The development of the Haggan project, Sweden, has presented a target requiring careful technical evaluation through the early development stages. The project represents a low-grade complex uranium resource, with significant vanadium, molybdenum, nickel and zinc credits. A process of mineralogical characterisation and multi-directional scoping metallurgical test work has been presented, focused on providing the basis to make a confident investment decision to progress the project to pre-feasibility evaluation. Implementation of this process has allowed the development of conceptual flowsheets targeted at efficient recovery of value metals and the rejection of technically ineffective options based on an understanding of the material and its behaviour.
