TBRC
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.
TBRC 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.
