Resumen:
Un centro de investigación polaco del sector de pirometalurgia, hidrometalurgia, tratamiento de minerales, tratamiento de residuos y chatarra y procesamiento de metales y aleaciones ofrece una tecnología de eliminación de zinc y otras sustancias en subproductos que contienen hierro (polvo y lodos) en procesos de calcinación reductora en un horno Waelz. El centro de investigación busca empresas interesadas en adaptar la tecnología, reducir costes de eliminación de residuos e incrementar la tasa de recuperación de metales. El objetivo es establecer acuerdos de licencia, investigación y cooperación técnica.


Details

Tittle:
Enrichment of the iron-bearing materials through zinc removal in reductive roasting process. A Polish R-Y-D institution is looking for commercialization partners.
Summary:
Polish R+D Institute operating in the field of pyrometallurgy, hydrometallurgy, treatment of ores and other mineral resources, treatment of scrap and wastes, processing of metals and alloys, is interested in license agreement and research / technical cooperation agreements for tailored solutions. This would be of interest to companies interested in technology adaption and for those who are looking for reducing waste disposal costs and raising higher than standard level the metal recovery rate.
Description:
The by-products from iron metallurgy, such as dusts and sludge from process gas dedusting, currently contain amounts of zinc which are too high to be redirected in the technological process. The offered technology allows removing zinc and other substances from those materials in the reductive roasting process in the Waelz kiln.
Steelmaking dusts and sludge cannot be redirected to the steel production process due to their high zinc content. Currently they are partly redirected to the process and the remaining part is temporarily stored.
The offered technology allows to process the dusts and sludge from steelmaking industry and to produce iron concentrate which contains less than 0,3% zinc. This product can be used in the iron and steel metallurgy as the substitute for the iron ore. Zinc concentrate produced as a by-product of the technology can be also utilized in zinc metallurgy.
The research Institute offers the possibility to test the material processing in laboratory and pilot scale as well as to implement this technology in the industry.
According to the philosophy of scientific research activity Institute is mainly interested in commercialization. Institute is aware of the diversity and variability of materials processed in their technology. This variability may require additional collaboration. Therefore Institute is interested in Research Cooperation Agreement and the Technical Cooperation Agreement as well is open to discuss the joint research and technology development.


Advantages and Innovations:
The main advantages of this technology is reducing waste materials in the industry. It allows to utilize all the steelmaking dusts and sludge. The technology also allows produce the iron ore substitute and process the iron-bearing materials which contain zinc in more effective and less complicated method than the alternative ones. Additional advantages are improvement in efficiency and lower cost of steelmaking.
Stage of Development:
Available for demonstration
