Mokhoa oa ho ntša metsi
Mokhoa oa ho sebelisa lihlapolli tsa manyolo ho ntša le ho arola ntho e ntšitsoeng mofuteng oa metsi a immiscible o bitsoa organic solvent liquid-liquid extraction method, e khutsufalitsoeng e le mokhoa oa ho ntša solvent. Ke mokhoa oa phetisetso ea bongata e fetisang lintho ho tloha mokhahlelong o mong oa mokelikeli ho ea ho o mong.
Ho ntšoa ha solvent ho sebelisitsoe pejana indastering ea petrochemical, organic chemistry, chemistry ea bongaka le chemistry ea tlhahlobo. Leha ho le joalo, lilemong tse 40 tse fetileng, ka lebaka la nts'etsopele ea mahlale le thekenoloji ea matla a athomo, tlhoko ea lisebelisoa tsa ultrapure le tlhahiso ea trace element, tlhahiso ea solvent e ntlafalitsoe haholo indastering ea mafura a nyutlelie, metallurgy e sa tloaelehang le liindasteri tse ling.
Ha ho bapisoa le mekhoa ea karohano e kang pula ea graded, crystallization graded, le ion exchange, solvent extraction e na le letoto la melemo e kang phello e ntle ea karohano, matla a maholo a tlhahiso, bonolo bakeng sa tlhahiso e potlakileng le e tsoelang pele, le ho le bonolo ho finyella taolo e ikemetseng. Ka hona, butle-butle e fetohile mokhoa o ka sehloohong oa ho arola likarolo tse ngata tsa lefats'e tse sa tloaelehang.
Thepa ea karohano ea mokhoa oa ho ntša solvent e kenyelletsa ho kopanya tanka ea tlhaloso, centrifugal extractor, joalo-joalo Li-extractants tse sebelisetsoang ho hloekisa lefats'e le sa tloaelehang li kenyelletsa: li-extractants tsa cationic tse emeloang ke acidic phosphate esters tse kang P204 le P507, anion exchange liquid N1923 e emeloang ke li-amine, le li-solvent extractants. e emeloang ke li-ester tsa phosphate tse sa nke lehlakore tse kang TBP le P350. Li-extractants tsena li na le viscosity e phahameng le ho teteana, ho etsa hore ho be thata ho arohana le metsi. Hangata e hlapolloa ebe e sebelisoa hape le metsoako e kang parafine.
Mokhoa oa ho ntša ka kakaretso o ka aroloa ka mekhahlelo e meraro e meholo: ho ntšoa, ho hlatsuoa, le ho ntša morao. Lisebelisoa tse tala tsa liminerale bakeng sa ho hula litšepe tse sa tloaelehang tsa lefatše le likarolo tse qhalakaneng.
