This invention offers a method of indium zinc alloy vacuum distillation dezincing.Its key point is using indium zinc alloy or metal raw indium as material, the content of zinc from 50% to 0.5%,take vacuum distillation, making the content of zinc to 0.001%. Extending time and temperature properly can even low the content of zinc. Controling distillation temperature under 700-1000 deg.C, degree of vacuum under 10Pa, dealing time 1-5 hours,the content of impurity zinc can low to high pure indium's require. This invention is used to dezinc of raw indium or indium zinc alloy, make pure indium, be low environmental pollution, low laber intensity, low cost of metal indium, high recovery of metals.
