Apstrakt
Litijum je postao metal od ogromnog interesa u celom svetu. Široka upotreba punjivih baterija za čitav niz primena podstakla je brzi rast potražnje za litijum karbonatom. Ovo jedinjenje se dobija kristalizacijom, reakcijom sa litijum hloridom (u rastvoru) uz dodavanjem natrijum karbonata. Niske stope taloženja u bazenima za isparavanje predstavljaju problem u procesu kristalizacije. Iz tog razloga, u ovom radu su izvršena ispitivanja sedimentacije minerala upotrebom dva tipa flokulanta sa različitim jonskim naelektrisanjem. Ispitivanja su izvedena na laboratorijskom nivou koristeći različite doze za svaki flokulant, a cilj istraživawa je bio postizanje povećanja asadržaja čvrstih materija u sedimentu. Anjonski flokulant je imao bolje performanse u poređenju sa kationnim flokulantom, povećavajući brzinu taloženja litijum karbonata do 6,5 puta. Međutim, slični sadržaji čvrstih materija dobijeni su upotrebom katjonskog flokulanta u dozi nižoj 3,5 puta, što ga čini flokulantom izbora sa ekonomskog stanovišta.
