A process for the hydrometallurgical processing of spent budget - and batteries

摘要

the invention relates to a method for the pyrometallurgical treatment of spent portable batteries to recover the budget and especially metalliferous materialswhen the batteries by crushing and separation of the scrap resulting fine powder by acid sensitive and at least a large proportion of the ingredients of the powder in the solution is brought to at least one other in the process of selectively obtaineda metal as the main constituent metallsalzlu00f6sung containing the metal raw material is recovered.$a, without a great deal of investment and running costs of the verfahrensprodukte, the metals contained in the acidic metallsalzlu00f6sung as chemiegrundstoffe reclaim and exploit the metal from the metallsalzlu00f6sung as chemiegrundstoff, such as carbonate, hydroxide and / or oxihydrat, aufkonzentrierte metallu00f6sung and / or metallic salt.
