Abstract
The method is used for the treatment of arsenic containing zinc slags, produced during pyrometallurgical treatment of the cake from the hydrometallurgical treatment of melting wastes. It ensures the separation of the arsenic in the form of insoluble compounds in part of the slag, which is either sent to the waste heap or is treated for the extraction of valuable components, and the remaining part containing insignificant quantities of arsenic is treated to commercial end products. The crushed slag is subjected to dry magnetic separation until the production of magnetic fraction containing the basic amount of arsenic in the form of insoluble compounds, which is deposed or treated by known methods for the extraction of the valuable components. The non-magnetic fraction is subjected to wet grinding until the uncovering of the mineral grains, and then sulphide flotation is undertaken by the separation of sulphide concentrate which is sent to metallurgical treatment, and the wastes from the flotation containing vitreous mass and zinc spinel is subjected to sulphuric acid zinc extraction at temperatures between 60 and 65 degrees C. From the filtrate produced, zinc sulphate is separated by means of crystallization, and the lye is neutralized for the separation of iron hydroxide.
