Description

Technical Field

[0001] This utility model relates to the field of slag treatment technology, and in particular to a slag acid leaching heavy metal recovery device. Background Technology

[0002] Slag acid leaching for heavy metal recovery utilizes acids such as sulfuric acid to dissolve heavy metals in slag. The slag is first crushed and screened for pretreatment. Then, the acid reacts with the metal compounds, dissolving the heavy metals in the solution. After solid-liquid separation, the heavy metals are extracted using methods such as precipitation, extraction, or electrolysis, enabling the recovery of resources such as copper, zinc, and nickel. This technology reduces slag pollution and creates economic value, and is widely used in the treatment of non-ferrous metal and precious metal slag, as well as electronic waste. However, careful control of acid consumption and environmentally friendly wastewater treatment are crucial.

[0003] Existing acid leaching heavy metal recovery equipment requires frequent addition of acid during acid leaching, which is inconvenient to use.

[0004] Therefore, a slag acid leaching heavy metal recovery device is proposed. Utility Model Content
