典型含锑物料的湿法分离锑研究
Study on the Separation of Antimony by Hydrometallurgy with Typical Material Containing Sb
摘要
Abstract
With the continuous depletion of antimony resources,antimony is a valuable strategic resource for a country.Antimony recovery must be paid attention to,and the efficient using of antimony material is the first,and dealing with this materials is the key to recovery antimony or its compounds from them.This paper introduced several methods for the separation of antimony by hydrometallurgy with typical material containing Sb.A large number of research results were reviewed,summarizing material leaching of antimony is generally alkaline leaching.Oxidation is easy to occur under alkaline conditions,which often combined with oxidant Sb3+oxidation into Sb5+.It is pointed out that the pressure can improve the leaching rate of antimony.When Na2S is added into the alkaline solution,antimony can be precipitated to form sodium antimony to recover antimony.By processing for the separation and extraction of antimony from antimony containing materials,it is concluded that the wet treatment of the material containing antimony has the advantages of high recovery rate,easy separation of antimony and other materials,friendly environment,low cost and low equipment requirements.Antimony containing materials are often associated with other valuable metals:arsenic,bismuth,lead,gold,silver,copper,iron,etc..These metals are recovered by leaching residue or leaching solution,which can not only achieve the recovery of antimony,but also other valuable metals.The wet treatment of antimony containing materials will gradually replace the fire method,and more and more attention has been paid to the wet treatment of antimony containing materials.关键词
