Изобретение относится к области гидрометаллургического выделения цинка из шламов, образующихся в процессе очистки сточных вод, в частности из шламов производства химического волокна, и может быть использовано для переработки шламов, осажденных из рудничных (шахтных) вод. С целью упрощения процесса при расширении возможности вовлечения в переработку низкопроцентных известковых шламов последние изначально выщелачивают раствором серной кислоты умеренной концентрации, а полученный раствор цинкового купороса направляют на осаждение пигмента сульфопона путем сульфидизирующей обработки его серой элементарной и известью.The invention relates to the field of hydrometallurgical separation of zinc from sludge formed during wastewater treatment, in particular from sludge from the production of chemical fiber, and can be used for processing sludge deposited from mine (mine) water. In order to simplify the process while expanding the possibility of engaging low-grade lime sludge in the processing, the latter are initially leached with a solution of sulfuric acid of moderate concentration, and the resulting solution of zinc vitriol is sent to precipitate the sulfopone pigment by sulfidizing it with gray elemental and lime.
