1. Designation and area of application

7.3 Slag Reprocessing DiagramShaft furnace is high efficiency equipment with high heat-availability factor of fuel consumption due to material and gases opposite flow within the furnace. The main purpose of slag processing is extraction copper out of copper, brass and bronze slag fractions of 30 – 100 mm with copper content not less than 5 %, receiving molten metal and pouring it into moulds or a ladle.

Characteristics of raw material

The raw material for the shaft furnace is the slag obtained from the fire refining of copper-containing scrap, with a copper content of 5% or more.

Melting of the stock is carried out by burning of coke.
