FIELD: metallurgy.
SUBSTANCE: method includes sulphatisation of concentrate by sulfuric acid, water leaching of sulphatisated concentrate, leaching pulp neutralisation and separation of neutralised leaching pulp for filter cake and sulfate solution. Additionally leaching pulp is neutralised by reactive concentrate of β-spodumene. During leaching it is received rich of lithium cake and it is used for manufacturing of lithium ceramics and glassceramics.
EFFECT: exclusion of lithium revolution in process and receiving of rich of lithium cake - raw material for manufacturing of lithium ceramics and glassceramics.
