Latest Patents

Fossi holds a patent for a process titled "Process for the recovery and purification of germanium from zinc ores." This invention provides a method for recovering germanium as germanium oxide from germaniferous metallic zinc. The process involves distilling the germaniferous metallic zinc under non-oxidizing conditions, recovering the distillation residue that contains the germanium, and leaching the residue with chlorine water to convert the germanium into germanium tetrachloride. The hydrolysis of germanium tetrachloride into germanium oxide is a crucial step, and the germanium oxide can optionally be reduced to metallic germanium.
