In recent years, global crude steel output has been increasing with the economic development and rising demand for steel in real estate, processing and manufacturing industries [1], [2].China's crude steel production reached 1.03 billion tons in 2021, which is the highest globally [3], [4].However, China has been importing a large …
By reprocessing tailings, dewatering them and then storing them in a dry stack, mines can remove some of the economic, environmental and societal risks …
1.Introduction. The tailing recycling machine is suitable for the purification of all kinds of rare metal ore (tungsten, tin, gold, copper, lead, zinc, chromium, titanium, zirconium, rare earth, monazite, tantalum and …
Recovery of Mine Wastes through Reuse and Recycling Reusing mine waste means using the material in its entirety without processing it in a new application. Recycling, on the other hand, extracts new valuable components from the waste or uses the waste as an input to the manufacture of a valuable product or application through processing [48].
In summary, the implementation of the new procedure shows that the waste tailings can be fully reused without the failure of the USOP. Compared with 60%–75% recycling in underground stopes and a small proportion in open pits, the new procedure reduces the residual waste tailings on surface and improve the stability of the USOP at …
Secondary recycle waste of rare earth tailing was used to prepare cement. • Residual rare earth oxide contributed to formation of C 3 S and C 4 AF. • Secondary recycle waste of rare earth tailing prolonged setting time of cement. • The increased C 3 S and C 4 AF resulted in improvement of early strength of cement.
