Germanium is mined primarily from sphalerite (the primary ore of zinc), though germanium is also recovered commercially from silver, lead, and copper ores. At Ceniga's Masonry, we know what it takes to deliver impeccable results! [57][58][59] Some zinc-copper-lead ore bodies contain enough germanium to justify extraction from the final ore concentrate. Under normal conditions GeI4 is a solid, GeF4 a gas and the others volatile liquids. In 1869, Dmitri Mendeleev predicted its existence and some of its properties from its position on his periodic table, and called the element ekasilicon.
