Guide: US resource companies are developing a process, separating pure rare earth metal from electric vehicles or lithium-ion batteries based on renewable energy plants. This technique is described as a two-zone ligand auxiliary replacement chromatography (LAD), which can have high yield and a metal having more than 99%. Headquartered in the US raw materials Suppliers US resource companies are developing a technique for recovery of righteous metals such as recovery of neodymium (ND), 镨 (PR) and 镝 (DY) after the life cycle of lithium ion batteries.

A paper published by the American Chemistry Society shows how researchers in the University of Purdue, Indiana extract pure carbon from plastic waste, and turn it into an anode material of a lithium-ion battery. The battery is a toy truck supply power. The team claims that this method can be easily expanded.

In addition, the development of electric vehicles can also create a considerable market for this anode material. The company's patented techniques obtained from Purdue University in February, including a lithically rare earth metal and key elements from coal by-products, recovered permanent magnets and electric vehicles or lithium-ion batteries used in renewable energy plants. Process.

This technique is described as a two-zone ligand auxiliary replacement chromatography (LAD), which can have high yield and a metal having more than 99%. Replacement chromatography is a preparation technique, usually used to place the sample on the stroke, then replace it by solute. The system is based on partition shunting method, and it is said that its overall production capacity can exceed 100 kg of rare earth elements per day per cubic meter.

It wants three columns, an extractant, ethylenediamine tetracetic acid (EDTA) and other undefined environmentally friendly chemicals. It is said that LAD has no adverse effects on the environment than the traditional acid-based method using the two phase fluid-liquid extraction process. Researchers said on the other hand, due to the high degree of chemical and physical properties of rare earth metals, there is also difficulties in separating rare earth metals.

US Resources CEO Mark Jensen said: "Overall, our technology and raw process chain enable us to help restore these key materials in the most sustainable and environmentally friendly way to help restore these key materials. The team of Purdue University is important part, we look forward to actively promoting technology, showing low-cost and environmentally sensitive technologies. "At the same time, other scientists at Purdue University have developed a process that extracts pure carbon from plastic waste, and converts it into an anode material of lithium-ion batteries.
