Enriching Indium Using Neutralization from Solution Bearing Indium

Abstract:

An experimentation project has been put forward to enrich indium from sulfuric acid leaching solution bearing high content of indium: preneutralization using calcine---reduction using zinc sulfide concentrate---neutralization using limestone for precipitating indium, and ascertained optimal dosage of reagent in every procedure through experiment under certain condition: the dosage of calcine is 1.3 times of theoretic value, the dosage of zinc sulfide mineral concentrate is 2.2～2.3 times of theoretic value, the dosage of limestone is double of theoretic value. On this optimal condition, the straight recovery rate of indium is more than 97%, and the content of indium sediment from precipitating is more than 0.1%.
