Thermal Pre-Treatment

Incineration enables metal that could otherwise not be recovered to be processed and concentrated into an ash that can then be processed and refined.


RSBruce are unique in that we choose to operate a batch incinerator for high-value materials, enabling us to segregate each customer’s materials, to accurately determine the value of the metal contained within each batch, whilst eliminating potential losses between lots and cross contamination.  


The process of incineration increases the concentration of the metal through a loss on ignition ( LOI )  giving a resultant mass of ash that can then be processed further to extract and refine the metal. 

The batch sizes, the addition of additives, and burn temperature of the incinerator are closely calculated and controlled to optimise the process. An in-line thermal afterburner and countercurrent liquid scrubbing system in combination with regular stack monitoring ensure that emissions are controlled
