Recycling
Recycling has been important for the steel industry for a long time and the portion of recycled material increases every year. With the increased amount of scrap it is even more important to keep track of the composition to ensure that the level of unwanted elements are enriched in the steel. With today’s trend of urban mining it is attractive to refine the recycled material. Our converter processes are tailormade for different material and if coupled with a downstream metal granulation plant, attractive raw material is achieved.
Metal recycling for a sustainable future
Recycling in practise
In theory, metals are infinitely recyclable but in reality recycling technologies are often not efficient enough to separate valuable secondary resources that are vital for a sustainable steel industry. Therefore, there is a demand for metallurgical processes which ensure the desired composition of the material in order to close the loop of recycled metals.
Handling of intra-industrial waste
The steel industry has become increasingly dependent on recycled scrap material with the emerging shift from ore to secondary resources. However, there is still a challenge to handle the intra-industrial waste such as dust and slag to retrieve precious metals that otherwise would go to waste.
Vanadium recovery from slag
Steel plant slag is rich in iron, but typically also includes unwanted residuals, such as vanadium, that need to be separated in order for the iron to recirculate into the steelmaking processes.
UHT has developed a converter process for selective oxidation of vanadium in re-melted steel slag, which enables separation of iron and vanadium. Further processing of vanadium into ferrovanadium, as well as the purified iron, create desirable products that can be re-introduced to the market.
Granulation of e-scrap
Recycling of electronic waste, or e-waste, is essential for reducing the environmental impact of electronic devices and prolong the life cycle of precious metals. The recycling plants typically include a smelting facility and further refining processes for extraction of copper and other metals converting e-waste into e-scrap. To make sure that there is no disruption of the main metal flow, integration of the GRANSHOT® granulation process ensures rapid solidification of e-scrap into easy-to-handle granules within the plant, or as a commodity of its own.
Recirculation of industrial dust
European stainless steel producers generate approximately 20 – 30 kg dust per ton of produced stainless steel. The dust formed during various stages of the production process contains valuable metals such as Cr, Ni and Mo. The metal compounds contained in the dust residues are reduced to metallic form in a plasma arc furnace and can thereafter be granulated directly via the GRANSHOT® process into valuable granules and circled back to the steel producers.
