Abstract

Patente de Invenção: <B>"PROCESSO PARA RECUPERAçãO DE áCIDOS DE SOLUçõES METALìFERAS DESTES áCIDOS"<D>. A invenção refere-se a um processo para a recuperação de ácidos a partir de soluções metálicas destes ácidos, de preferência, de HF, HNO~ 3~, Fe, Cr, compostos de níquel e misturas destes compostos, mediante evaporação e dissociação pirolítica em ácidos e óxidos de metais. Ela é principalmente caracterizada pelo fato, de ser previsto um reator aquecido, subdividido por instalações em duas zonas, sendo que na primeira zona, superior realiza-se uma evaporação em baixa temperatura e na outra zona, diretamente conectada, realiza-se uma decomposição em temperatura elevada.
