Substantial germanium resources are available in other metal ores deposits in Alaska, Tennessee, and Washington. The owner of a zinc smelter in Clarksville, TN, planned to construct a new $90 million gallium and germanium processing plant at the site, the plant could recover an estimated 40 tons of germanium per year.
gallium: US$225 million. germanium: US$39 million. The market for the two critical minerals may be smaller compared to other major metals, such as copper and lithium, but their use in high-growth, strategic industries, including defense, hi-tech and green energy, give them significant market leverage. And, in turn, China's monopoly of …

Germanium, Ge. Germanium is a brittle, lustrous, gray-white metalloid with a diamond-like crystalline structure. While opaque in the visible spectrum, it becomes transparent in the mid-infrared range, from approximately 2 µm to 14 µm. This unique transparency makes germanium highly valuable in the field of infrared optics.
