FACT SHEETS
- WP1 Raw materials sampling and characterization: The main objective of WP1 was to collect and characterize primary and secondary raw materials samples to be studied and tested.
- WP2 Enhanced performance flotation process: WP2 developed enhanced flotation techniques including energy efficient comminution and more specific reagents.
- WP3 Development of integrative atmospheric leaching process aimed to develop an innovative hydro-metalurgical process at atmospheric pressure able to efficiently leaching complex-low grade copper concentrates and polymetalic concentrates.
- WP4 Development of integrative pressure leaching process: Main objective was to develop a pressure leaching process, capable of efficiently dealing with low grade copper concentrates, polymetallic concentrates, and flotation middlings, to yield high quality metal products.
- WP5 Development of integrative bioleaching process had the objective to develop and test innovative bioleaching processes capable of efficiently dealing with Low Grade copper concentrates, polymetallic concentrates, and flotation middlings produced in existing flotation plants (WP2), to yield high quality and added value metal products.
- WP6 Valorisation of tailings, wastes and effluents aimed to benefit old tailings and metallurgical wastes with enough metals content, critical elements or value raw materials; maximizing reuse of water to minimize water consumption and enhance purification of effluents.
- WP7 Technologies Assessment and Project Evaluation evaluated the developed novel leaching technology, defined specific conditions and potentiality to apply the innovative developed technologies in existing hydrometallurgical plants or in new projects, checked potential synergies among industries to provide possibilities for integration of the technology in existing plants, and identified the environmental burden, by means of a LCA approach.
