Recycling e-waste has been a significant topic for environmental protection and also for resource recovery. Waste tantalum capacitors (WTCs), widely existing in discarded small appliances, are rich in high quality tantalum (Ta) resources. However, recovering Ta from WTCs is difficult due to the tightly covered mold resin. This study proposes an efficient …

Chlorination process, in chemistry, is a halogenation reaction using chlorine. Because chlorine is a highly efficient disinfectant, chlorine is widely used in the treatment of water. In this case, the chlorination process is the addition of chlorine or chlorine compound. Aqueous free chlorine solutions contain three species in equilibrium, Cl 2 ...

Our trained staff also provide on site taste and odour analysis. Our mains chlorination certificates are highly detailed and provide auditable proof through photographic evidence of the whole process.

Tantalum chloride is used as a feed material for the plasma reduction using hydrogen and in the chloride bath fused salt electrolysis routes to produce tantalum. Most of the tantalum, however, occurs in nature in the oxide form. The traditional chlorination process employs gaseous chlorine and carbon as reductant at high temperatures (1073 …

One may mention that the different minerals of tantalum and niobium occur in their own distinct deposits but they are also frequently present as inclusions in cassiterite (SnO 2), which is the main mineralogical source of tin.During the smelting of tin, the process concentrates tantalum and niobium in slags along with other elements such as …

It is used as an alloying element in super-alloys for jet turbine blades (Damm, 2018; Geological Survey, 2022 ). Because of its high corrosion resistance, tantalum is used in chemical processing equipment (Damm, 2018). Tantalum is used for prosthetic devices, hip joints etc., because of its good biocompatibility (Nassar, 2017).

The gravity separation takes advantage of the high density of the Ta-bearing phases, with specific density in the range 6 to 8. − Selective reverse flotation to concentrate the finest material − Low and high intensity magnetic separation to remove companion magnetic phases. − Thickening circuit to recycle the process water.
