What the programme covers
Temperature
Hydrometallurgy uses aqueous chemistry; pyrometallurgy uses high-temperature smelting.
Lithium recovery
Hydrometallurgy can recover lithium directly from black mass.
Nickel and cobalt
Both routes can recover them, with different intermediate products.
Energy demand
Smelting generally requires more thermal energy.
Feed flexibility
Pyrometallurgy tolerates mixed feed; hydrometallurgy rewards sorting.
Product route
Hydrometallurgy can produce battery-grade salts closer to cathode inputs.

Frequently asked questions
What is the main difference?
Pyrometallurgy smelts batteries at high temperature into alloy and slag; hydrometallurgy dissolves prepared black mass and selectively recovers metals from solution.
Which route recovers more lithium?
A well-designed hydrometallurgical route generally recovers more lithium because lithium can otherwise report to smelting slag.
