Rare and ValuableMetals Recovery
GSAe technology employs a sequence of hydrometallurgical and pyrometallurgical processes to extract metals such as vanadium and nickel from a variety of feedstocks.
Processing
The core of the technology is acidic and alkaline leaching of feedstocks, followed by selective metal precipitation, filtration of the precipitates and roasting stages as required. The technology can be run in either batch or continuous configurations. Over many years we have optimised this technology, adapting the chemistry for different qualities of feed-stock to isolate and extract a variety of metals as high purity saleable products and leaving non-hazardous wastes.
Technology Feedstocks
- Power station fly ash
- Gasifier residue
- Flexicoke
- Slurry hydrocracking
- Spent sulphuric acid production catalyst
- Spent refinery processes catalyst
- Spent fine chemical and speciality chemical catalyst
- Ores and ore concentrates
