Abstract: Using tara powder from Peru as raw material, rate of Ge precipitation from industrial mining liquor contaning zinc sulfate and germanium ion as index, the effects of extraction, refining and post-processing of tara extracts on the rate of Ge precipitation were studied. The results showed that using organic solvents (methanol, ethanol, ethyl acetate) extraction instead of water extraction, rate of Ge precipitation was more than 98%. Degumming of the extract with activated carbon and salting washing as well as through complexation by adding 1 % sodium chloride ammonium and 1% nitrilotriacetic acid effectively reduced non-tannin content in the product and enhanced the rate of Ge precipitation. When tara powder and gall flower of mixed in 8:2 as raw material,followed by complexation of the extract, the rate of Ge precipitation reached 99.05%. The cost of the product was reduced, as well.
