Cobalt Halides TRIZ Cases
- Battery Metal Recovery Using Hydrobromic Acid and Bromate Separation
Hydrobromic acid leaches spent battery cathodes without added peroxide, then bromate enables manganese separation and lithium recovery.
- Cobalt Chloride Purification via Nickel Cementation
Nickel cementation reduces copper concentration in cobalt chloride solutions, avoiding complex extraction equipment and harmful gas generation.
- Cobalt Chloride Purification via Nickel Cementation
Acid washing of metallic nickel enables efficient copper precipitation in cobalt chloride solutions without excessive heat generation.
