When the acid solution comes into contact with iron impurities in lithium battery materials, a chemical reaction occurs to form soluble iron salts. These iron salts are as if dissolved by the acid solution. As the solution flows, we can use PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC separation to separate other insoluble substances from the solution, thereby removing iron impurities.
We can also add precipitating agents to make iron ions form precipitates; common precipitating agents include sodium hydroxide and sodium carbonate. When these precipitating agents come into contact with iron ions in the solution, they undergo a chemical reaction to form insoluble iron precipitates. These precipitates, like small particles, gradually settle out of the solution and can be separated using PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC separation to achieve iron removal.
The greatest advantage of the chemical PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal process is its ability to remove various forms of iron impurities, including weakly magnetic and non-magnetic iron compounds. These hidden enemies that are difficult to remove in magnetic separation processes are revealed before the chemical iron removal process, leaving no place for them to hide
