Abstract
Способ получения литийсодержащего глинозема из сподуменового концентрата, включающий активацию концентрата, сульфатизацию активированного концентрата, выщелачивание продукта сульфатизации с извлечением сульфатов алюминия и лития в сульфатный раствор, осаждение из сульфатного раствора литийалюминийсодержащего осадка раствором алюмината натрия и едкого натра, приготовленным растворением технического гидроксида алюминия в растворе едкого натра, отличающийся тем, что перед осаждением из сульфатного раствора литийалюминийсодержащего осадка сульфатный раствор обрабатывают раствором едкого натра с осаждением смеси гидроксида алюминия и примесей при рН=7,5÷8,0, осажденную смесь отделяют от сульфатного раствора, из которого осаждают гидроксодиалюминат лития раствором алюмината натрия и едкого натра, приготовленным растворением технического гидроксида алюминия и осажденной из сульфатного раствора смеси гидроксида алюминия и примесей в растворе едкого натра с последующим отделением полученного раствора алюмината натрия и едкого натра от нерастворимых примесей, а осажденный гидроксодиалюминат лития прокаливают при температуре 400÷450°С с образованием очищенного от примесей литийсодержащего глинозема с повышенным содержанием лития.A method for producing lithium-containing alumina from spodumene concentrate, including activation of the concentrate, sulfatization of the activated concentrate, leaching of the sulfation product with the extraction of aluminum and lithium sulfates into a sulfate solution, precipitation from a sulfate solution of lithium-aluminum-containing precipitate with a solution of sodium aluminate and sodium hydroxide, aluminum prepared by dissolving technical sodium hydroxide sodium hydroxide, characterized in that before precipitation from a sulfate solution of a lithium-aluminum-containing precipitate, the sulfate solution is treated with a sodium hydroxide solution with the precipitation of a mixture of aluminum hydroxide and impurities at pH = 7.5 ÷ 8.0, the precipitated mixture is separated from the sulfate solution, from which lithium hydroxodialuminate is precipitated with a solution sodium aluminate and sodium hydroxide, prepared by dissolving technical aluminum hydroxide and precipitated from a sulfate solution of a mixture of aluminum hydroxide and impurities in a sodium hydroxide solution, followed by separation of the resulting pa solution of sodium aluminate and caustic soda from insoluble impurities, and the precipitated lithium hydroxodialuminate is calcined at a temperature of 400 ÷ 450 ° C with the formation of lithium-containing alumina purified from impurities with an increased lithium content.
