Japan's move research and development of rare earth extraction using salmon milt

According to Japanese media reports, the Japanese city of Hiroshima university and aichi prefecture AisinCosmos institute of scientific research team discovered recently that salmon milt can be effectively separated from the ore and extracting rare earth. Researchers on the 17th "international resources business summit held in Tokyo on announcing the results.

The report said a total of 17 kinds of rare earth, from the contain a variety of rare earth minerals separation recycling of rare earths needed to use special resins, trouble and expensive. Scientific research team member, Hiroshima university professor takahashi jia's (environmental chemistry), said: "if you use the most discarded milt, low cost and environmentally friendly."

Team noticed milt is rich in phosphate, salmon milt dry processing is made after the powder in the experiment, then the powder into the beaker containing liquid rare earths. Results show that salmon milt has high adsorption ability of rare earth with bacteria.

Milt after chemical treatment, can extract all kinds of rare earth in the end. Unlike bacteria, milt without cultivation can be get easily, made into powder is also easy to save, after the team believes that this method has higher practicability. Milt refers to the testis, fish is fish organs of manufacture and storage of sperm. Milt contains a kind of special protein, called protamine, is one of the most simple alkaline protein in nature. It is the medicine of the bleeding.

Rare earth of Japan's high-tech sector and the automobile industry, a rare metal material. In recent years, the Japanese government has constantly in search of rare earth in global scope, and Vietnam, Mongolia and other neighboring countries signed the relevant agreement; Japanese industries are also constantly through the experiments, various "new hire" try to extract rare earths, in an effort to achieve recycling, finally get rid of dependence on China.

May 10, the yomiuri shimbun, Japan has reported that the Japanese developed using "microbial capsules" cheap, fast recovery of rare metal from industrial waste water, by day and will be in 2013 years under Benson RenDan and mitsubishi company for domestic factories to sell or lease.
