Dilution Furnace

​

Description: The dilution furnace operates by processing tin-rich slag from the electric arc furnace (EAF) to recover additional tin metal. Through precise temperature control and flux addition, the dilution furnace effectively separates residual tin from the slag while diluting impurities, ensuring high recovery rates and minimal waste.

​

 

Key Advantages:

​​

  • Efficient tin recovery from slag

  • Lower operating costs compared to EAF

  • Compact design suitable for small smelters

  • Shorter process times for increased throughput

  • Minimal emissions

  • Energy-efficient operation with low power requirements

  • Seamless integration with EAF systems by taking liquid molten slag directly from the EAF

 

Here's how a dilution furnace fits into the smelting process:

 

  1. Recovery of Tin from EAF Slag: The dilution furnace is designed to recover tin from the slag produced by electric arc furnaces (EAF), boosting overall metal recovery rates while minimizing waste.

  2. Low Operating Costs: With operational expenses at only 1/5th of a standard EAF, the dilution furnace offers a cost-effective solution for smelters or facilities with lower throughput.

  3. Shorter Process Time: The furnace eliminates the need for lengthy beneficiation cycles or multiple EAF passes, significantly shortening the process while maintaining high tin recovery efficiency.
