NICKEL & COBALT RECOVERY
Future Environmental Services
Nickel/Cobalt rich filtercake material is recovered by steam drying. The resulting concentrate can then be re-used or recycled. We also recover other valuable metals such as copper, tin and cobalt.
Processes used include precipitation, steam stripping, sludging and steam drying. Metal bearing solutions are stripped of any ammonia through the steam stripper plant before sludging through a high-pressure filtration press to produce a metal hydroxide filter cake.
Metal Hydroxide Filtercakes are fed through a tubular dryer, which is an indirect contact dryer that uses dry saturated steam as the heating medium.
RECOVERY FROM INDUSTRIES:
The valuable metal concentrates produced are suitable for re-use or smelted and recovered as metal or aqueous solutions which go back into the industry.
FIS recycles and recovers metal concentrates such as nickel, copper, cobalt and tin from industries such as:
We also produce metal concentrates from low metal content filtercakes, diverting waste currently being disposed to landfill by offering a recovery “R” Code allowing companies to meet the waste hierarchy set out in the waste framework.
