Top Blown Rotary Converter (TBRC)
The TBRC is a high-speed, rotating vessel fired by an oxy-fuel lances. Both the lancing technique and the rotation of the vessel provide remarkable augmentation in mass transfer rates compared with reverberatory or rotary furnaces. TBRC's can be used for smelting and refining in the same vessel.
For refining processes, such as the removal of base from precious metals, oxygen is applied. Applications include:
Reductive and/or flux smelting of base and precious metal concentrates, sweeps, residues and flue dust.
Fuming for elimination of selenium, arsenic, antimony and numerous other volatile metals.
Converting copper-nickel and pgm mattes.
Electronic scrap and photographic waste processing.
The Advantages of TBRC Processing
High process intensity
Low wetted surface & minimal inventory
High heat and mass transfer rates for rapid processing
50 - 70% thermal efficiency
Minimal process off gas handling
Simple & quick shell changing to minimize precious metal lockup
Control of furnace atmosphere by lance stoichiometry
JWT can advise on the appropriate selection of furnace and configuration of equipment to meet your needs.
One of the more common applications of the TBRC applications is the processing of lead, copper or nickel anode slimes for the recovery of precious metals. For more information go to Anode Slimes
