Project Idea Concept

By-products of the steelmaking industry shall be considered as a secondary raw material source due to their high content of iron and other metal oxides.

Today metallurgical treatment/extraction methods, such as pyro-metallurgical processes, are aimed to recover the metal oxides contained in different mediums: from ores to waste. In Steel industry most of these are devoted to the recover of Zn from filter dusts, thus representing an example of a waste stream generated by an industrial sector and recovered by another one.

The project concept is to extend this approach to the recovery of other valuable metals, including Fe contained in industrial by-products or waste. This will contribute to the 2030 target reduction

(up to 20%) of the non-renewable primary raw material intensity.

T

plasma technology

(electrical arc furnace), presently limited to the treatment of dusts from high alloyed steel production, can be widely employed and further developed to effectively recover raw materials in an economic and eco efficient way.

This responds to

SPIRE KA 4.3: Technologies for (pre)treatment of process and waste streams (gaseous, liquids, solids) for re-use and recycling

Idea Impact

The plasma technology can treat a large variety of waste streams: The by-product coming form steel industry:

slag, scale, dust, sludge Nonferrous waste:

The project the

idea is related to the SPIRE 7 call topics: development of new approach for the design and scale up of industrial process for metals recovery from waste solids (TRL 7)

integration with the currently existing plant/technology taking into account the links with primary processprove industrial relevance and feasibility of proposed technology by demonstration activities in industrial environment

The expected impact are:significant improvement of the resource efficiency increasing the recovery of material up to 40% by:maximum flexibility in the materials charged

tailor made according to the production size as well as market requirements.
