Product Description
Copper Slag Treatment Electric Furnace Equipment
High-Temperature Depletion · Cu-Fe Enrichment · Hot Slag Direct Feed · Low Energy & Eco-Friendly · Intelligent Operation
The copper slag treatment electric furnace (also known as copper slag depletion arc furnace / copper slag reduction furnace) is the core thermal equipment for copper smelting slag resource utilization, specifically designed for flash furnace slag, converter slag, and refining slag. Through high-temperature melting, reduction, and clarification at 1250–1500℃, valuable metals such as copper, iron, zinc, gold, and silver in the slag are efficiently enriched and recovered. The tailings are directly granulated for building materials, realizing zero solid waste discharge and high-value metal utilization.
Ideal for: Copper smelters, non-ferrous slag processing, hazardous waste recycling, secondary metals and more.
1. Equipment Composition (Furnace Body + Auxiliary Systems)
