Precipitation
Recovering a dissolved metal as a solid by adding a reagent that makes it insoluble — nickel and cobalt as hydroxides, lithium as carbonate with sodium carbonate. Co-precipitating nickel, manganese and cobalt together gives a precursor directly. [1]
- Also called
- hydroxide precipitation, carbonate precipitation
Example
Recycling and end of life: an example situation
High mass recovery alone does not establish battery-grade purity or refining energy demand.
Read Precipitation alongside Crystallisation in this context. Evaporating a purified solution until a battery-grade salt crystallises out — nickel sulfate, cobalt sulfate, lithium hydroxide — ready to be sold back to precursor and cathode plants.
Use in Lemonergy
Distinguish recovered material from a qualified product.
This is a reference concept. No executable Lemonergy block has been verified for this term.
