A new integrated sustainable processing system for ‘metal from slag’ recovery with higher technical, economic, energy and environmental performance than existing recovery processes.

Periodic Reporting for period 1 - Ultroslag (A new integrated sustainable processing system for ‘metal from slag’ recovery with higher technical, economic, energy and environmental performance than existing recovery processes.)

Reporting period: 2014-10-01 to 2015-03-31

"Slag is a by-product of metal smelting, and at least 43m Metric Tonnes of it are known to be produced every year in the process of refining metals & making alloys. Slag has many uses, and rarely goes to waste, but it is used in low value applications such as ballast in concrete and in aggregate road materials. However, slag retains significant amounts of metals & these are sometimes recovered by re-melting the slag, but this is extremely expensive with a very high energy burden and Carbon footprint. Our proven ""Ultroslag"" concept is to use a novel technology to selectively break down the non-metallic components of slag from the metallic particles. We have completed a proof of concept project, adding our own innovations to this process and the results demonstrate full separation of all metal from non-metal particles. The benefits of our process vs existing process are: • >90% saving in energy consumption & cost, • Rapid local turnaround of material, • >90% cut in the carbon footprint, • Retain control of metal recovered. • Enable smelters to recover more metal and on-site, removing the need to export for processing, • Retain control of metal recovered. • Recovery of salt as an added revenue."
Project objectives for the period: Research for, and compiling of a feasibility study for the Ultroslag technology

Work Progress and achievements: The study has been prodcued in accordance with the Phase 1 objectives and work programme.

Deliverables: The production of the feasibility study achieves the deliverables as set out in Annex 1 ofd the grant agreement
The final result (feasibility study) is complete and has been used to validate the business idea and ongoing development process.
