Abstract

The invention discloses a recovery device for extracting metal from acid-making high-iron cinder and a use method thereof, and particularly relates to the field of cinder metal recovery devices. The recovery device comprises a shell, a combustion cavity is formed in the shell, and a supporting mechanism is arranged in the combustion cavity. The supporting mechanism comprises at least two supporting plates, through holes are formed in the supporting plates, and the through holes are sequentially reduced from top to bottom. The supporting plates comprise a fixed plate connected with the inner wall of the combustion cavity, a movable plate is arranged above the fixed plate, the tops of the through holes are connected with the movable plate, and the bottoms of the through holes are connected with the fixed plate. Through the arrangement of the supporting mechanism, when a driving wheel rotates, a rolling wheel is vibrated through an uneven vibration groove, cinder raw materials located on the movable plate are separated through vibration, the cinder raw materials are prevented from being gathered together, the cinder raw materials in different sizes are combusted in a layered mode, the cinder raw materials are combusted more sufficiently, and the metal extraction rate is high.

Description

technical field [0001] The invention relates to the field of recovery devices for slag metals, more specifically, the invention relates to a recovery device for extracting metals from acid-making high-iron slag and a method for using the same. Background technique [0002] The treatment methods of metal concentrates in metal production mainly include direct cyanidation method, burning cyanidation method, bacterial oxidation method, and hot pressing method. The influence of harmful impurities is effectively eliminated through the pretreatment process, and the leaching rate of metals is improved. , and the main gold extraction method is the direct cyanidation method, which is to directly cyanide the concentrated ore suitable for direct cyanidation treatment with less harmful elements and a higher metal leaching rate to extract metals, and the cyanided tailings produced have always been The sulfur in the tailings is utilized, but the small amount of valuable metals such as lead...
