At TH Re-MINING, we strive to develop appropriate technologies for the separation and reprocessing of all components in toxic waste. The project of the utilization of secondary lead slag as a secondary raw material for the production of lead is therefore devoted to the reduction of the amount of toxic waste in the environment and aims to achieve the zero waste goal in the EU. The fact remains that slag, produced from battery paste during the obtainment of waste lead batteries, is disposed of in various landfills and dumps. These may contain large amounts of useful elements such as Pb (˂22%), followed by Zn and Cu, which are also highly migrating toxic elements. With careful analysis of elemental lead and slag, TH Re-MINING tries to reduce the presence of toxic elements in the environment on one hand but also to raise awareness of their appropriate use and disposal on the other hand.
European industry generates 1.3 million tons of electric arc furnace (EAF) and cupola furnace (CF) dust annually, both considered hazardous waste, which could be an alternative source of valuable metals essential for low carbon industry. The project DustRec aims to build capacities in the RIS region by developing feasible recovery technologies that generate minimal waste discharge and therefore improve environmental and social impacts.
Red mud (BRM) is a hazardous solid caustic waste that results from the digestion of bauxite ore with sodium hydroxide in Bayer’s alumina extraction process. In the ESEE region, more than 85 million tonnes of red mud from previous metallurgical activities have been landfilled. These tailings contain significant amounts of heavy minerals such as REE, Sc, Y, Zr, Hf, and Ti. The project aims to establish a self-sustaining network of stakeholders interested in the reprocessing of red mud tailings in the ESEE region through the extraction of heavy minerals containing valuable metals (REE, Sc, Y, Hf, Zr, and Ti) and the use of recycling residues in the construction sector.
A review of some concessions in the U.S. has shown that gold is present not only in the quartz veins but also in the tailings of earlier mining since the cut-off grade was much higher then. Its recovery could be economically viable through the use of various beneficiation techniques, which we are currently testing on the material.
