The germanium, a rare metal seldom mentioned, is withering away the hands of the industry. And the development of this resource in China, which is still in the initial phase of making germanium ingot and conducting rough processing, calls for people's watchful eyes, an industry expert told the National Business Daily (NBC) Friday.

As the world's second-largest reserve, China accounts for 41 percent of the whole reserve; while the US occupies 45 percent, which it has hardly exploited, said Yuan Li, a nonferrous metal analyst.' Z0 l" t' [- g8 N: S0 `' U: k
In order to effectively protect the resource, experts say that the Chinese government should collect germanium resources and help germanium-related companies form an industrial chain in the country.
