Abstract:

The extraction raffinate pretreatment can avoid environment pollution.Moreover，it is likewise an effective way of recovering valuable elements.This work proposes a new extraction raffinate pretreatment that is the ammonia precipitation.Principle of the new extraction raffinate pretreatment is to apply ammonium hydroxide to make pH≈7.5 of the raffinate，which can result in the valuable elements（Zn，Cu，Pb，Fe） forming precipitations of hydroxide and then the precipitations separate out quickly，however，the element As forms the FeAsO4 precipitation.After solid-liquid separation，adding Na2S into the filtrate can make some of the trace metal elements begin to precipitate.Finally，the goal that all valuable elements of the extraction raffinate can be recycled effectively comes true.It is found that treatment fluid can be used as a kind of the slurry in roasting cyanide during the process of acid leaching.

Key words: extraction raffinate pretreatment, ammonia precipitation method, waste acid liquor, valuable element collection
