After China announced the restrictions on the export of related items of 镓 and 锗, the US Pentagon plans to sign a contract with companies in the United States or Canada for the first time before the end of the year.

According to Bloomberg News on Wednesday (July 26), the Pentagon said that the proposed projects are similar to the waste flow in the tail mines or refining process to recover other minerals or the main number of additional numbers of the numbermineral.

According to Reuters, a spokesman for the US Department of Defense said that the US Department of Defense has reserves, but there is no reserves.The Pentagon plans to use its power under the National Defense Production Law to "prioritize" the contract before December 31, "focusing on recycling from the existing waste sedches from other products."

The Pentagon said that recycling instead of mining is the fastest way to improve the acquisition of materials, but the funds under the National Defense Production Law have "not granted mineral recovery projects" in the past.

Officials from the US Department of Defense declined to disclose how much funds will be invested in the contract or how many company contracts may be awarded.

The Ministry of Commerce and the General Administration of Customs announced on July 3 that from August 1, export control measures were implemented to implement export control measures to maintain national security and interests.China is an important producer of 锗 and 生产; these two metals are crucial to semiconductor, telecommunications and renewable energy industry.

锗 and 锗 are usually extracted during the mining operation of other raw materials.However, their processing and refining costs are very high, so they are often regarded by Western companies as waste, while China dominates the supply of 镓 锗 锗.
