：A high temperature process for leaching selected metal compounds, such as gallium or germanium, from ores containing those selected metal compounds is disclosed. The method generally includes contacting metal-containing ores with an admixture of nutrient medium and bacteria capable of leaching selected metal compounds contained in the ore.

Germanium (14067 views - Periodic Table Of Elements) Germanium is a chemical element with symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Pure germanium is a semiconductor with an appearance similar to elemental silicon.

Abstract: Germanium, gallium and indium are in high demand due to their growing usage in high-tech and green-tech applications. However, the mineralogy and the mechanisms of concentration of these critical elements in different types of hydrothermal ore deposits remain poorly constrained. We investigated the mineralogical distribution of Ge, Ga
