Abstract
Sposób biochemiczny otrzymywania metali ziem rzadkich z fosfogipsów charakteryzuje się tym, że substraty stanowiące fosfogipsy pochodzenia apatytowego i/lub fosforytowego oraz substancję organiczną i/lub zmacerowaną substancję pochodzenia roślinnego, doprowadza się do postaci zawiesiny wodnej, przy nawodnieniu około 90% i wskaźniku wagowym fosfogipsu do substratu organicznego co najmniej 1 : 5, poddaje się fermentacji za pomocą bakterii Desulfovibrio, korzystnie Desulfovibrio desulfuricaus w warunkach beztlenowych w temperaturze około 30°C i przy pH od 6,8 do 7,0, utrzymywanym przez dozowanie kwasu mlekowego w czasie nie krótszym niż 6 dni, przy powolnym mieszaniu i w razie spowolnienia fermentacji, wzbogacaniu inoculum do całkowitego rozkładu fosfogipsu i zaprzestania wydzielania się siarkowodoru, natomiast wydzielający się podczas fermentacji osad, zawierający metale ziem rzadkich oddziela się od lżejszego osadu węglanów wapnia, roztwarza w kwasie solnym 1 : 1, filtruje się i wydziela szczawiany przy neutralizacji amoniakiem do pH od 1,5 do 2,5, które suszy się i praży do uzyskania tlenków.The biochemical method of obtaining rare earth metals from phosphogypsum is characterized by the fact that substrates constituting phosphatogypsum of apatite and / or phosphorite origin as well as organic and / or macerated substance of plant origin are brought into the form of an aqueous suspension, with hydration of about 90% and a phosphogypsum weight index of of organic substrate at least 1: 5, is fermented with Desulfovibrio bacteria, preferably Desulfovibrio desulfuricaus under anaerobic conditions at a temperature of about 30 ° C and a pH of 6.8 to 7.0, maintained by dosing lactic acid for not less than 6 days, with slow stirring and in the event of slowing fermentation, enriching the inoculum to complete phosphogypsum decomposition and stopping the production of hydrogen sulfide, while the precipitate formed during fermentation, containing rare earths, is separated from the lighter calcium carbonate precipitate, it is dissolved in hydrochloric acid 1: 1, filtrate and isolate oxalates on neutralization with ammonia to a pH of 1.5 to 2.5, which are dried and roasted to obtain oxides.
