The Top Blown Rotary Converter (TBRC) is a pyrometallurgical furnace that can be used for the recovery, upgrade and refining of metals; this includes:
- Multi-purpose melting
- Recovery of metals such as iron, copper and zinc from slags and process wastes
- Recovery of precious metals from waste electrical and electronic equipment (WEEE)
It is the only one of its size in the UK.
Applications and Capability
- Enables scale up from laboratory testing to pilot scale to help establish mineral recovery rates and process dynamics
- Can be used to develop and evaluate pyrometallurgical recovery options
- Advanced smelting equipment which can be used for treating anode slime or lithium recovery and the oxidation or reduction of metals.
- 30 litre nominal capacity (120 litre total volume but held at an angle of 25°)
- Operating temperature up to 1600°C
- Rotation speed from 1 to 15rpm
- Tilting angles: 0° for loading, 65° for firing,130° for tapping
- Batch loading during process via vibratory feed system
- Door mounted water-cool oxy-fuel burner rated at 120kW
- Off-gas handling. Thermal oxidiser will treat any volatile organic compounds (VOCs), dioxins and furans
- Bag filter plant for dust recovery
The Top Blown Rotary Converter is part of a suite of pyrometallurgical pilot facilities from kilogram to tonnage scale at the Institute and is fully supported by laboratory scale analytical, characterisation and process modelling facilities.
