Mekhoa e meraro e Tloaelehileng ea Leaching ea Khauta

Mokgweng wa ho Dutla ha thepa, ho itshetlehile ka dipharologanyo tsa ditsela tsa phallo ya thepa e dutlang le di-reagent tsa ho dutla, mekgwa e meraro ya ho dutla e ka hlwauwa.

1. Co-current Leaching

Ka co-current leaching, lisebelisoa tse leached le leaching reaagents li phalla ka tsela e ts'oanang (Setšoantšo sa 1). Mokhoa ona o ka hlahisa leachate e nang le litaba tse batlang li phahame tsa likarolo tse shebiloeng mme o hloka tšebeliso e tlase ea li-reagents tsa leaching. Leha ho le joalo, lebelo la eona la leaching le lieha. Ho hlokahala nako e telele ea ho tsoa mali ho fumana tekanyo e phahameng ea leaching.

2. Cross - current Leaching

Ka har'a leaching ea hona joale, lisebelisoa tse koetsoeng li arotsoe ka thoko ka likarolo tse 'maloa tsa li-reagents tse ncha tsa leaching. Leachate e fumanoang ts'ebetsong e 'ngoe le e' ngoe ea leaching e romeloa ka mokhoa o ts'oanang bakeng sa ts'ebetso e latelang (Setšoantšo sa 2). Cross - current leaching e na le lebelo le batlang le potlakile la leaching le nako e khuts'oane ea leaching, e bakang sekhahla se phahameng sa leaching. Leha ho le joalo, molumo oa leachate o moholo, o na le li-reagents tse setseng tse ngata. Ka lebaka leo, tšebeliso ea li-reagents e ngata haholo, 'me litaba tsa likarolo tse lebisitsoeng ho leachate li batla li le tlaase.

3. Counter - ea hona joale Leaching

Khahlanong le - leaching ea hona joale, lisebelisoa tse senyehileng le li-reagents tsa leaching li tsamaea ka mahlakoreng a fapaneng. Ke hore, lisebelisoa tse senyehileng ka mor'a ts'ebetso e 'maloa ea leaching li kopana le leachate e ncha, ha lisebelisoa tsa pele tse silafetseng li kopana le leachate (Setšoantšo sa 3). Counter - leaching ea hona joale e ka hlahisa leachate e nang le litaba tse phahameng tsa likarolo tse lebisitsoeng le ho sebelisa ka botlalo li-reagents tse setseng ka har'a leachate, kahoo ho fokotsa tšebeliso ea li-leaching agents. Leha ho le joalo, lebelo la eona la leaching le tlase ho feta la cross - current leaching. Palo e kholoanyane ea mekhahlelo ea leaching e hlokahala ho fumana sekhahla se phahameng sa leaching.

Leaching ea tanka ea percolation e ka sebelisa mekhoa ea hona joale ea leaching, ea hona joale, ea sefapano - ea hona joale kapa ea counter. Heap leaching le in-situ leaching hangata li sebelisa mokhoa oa hona joale oa cyclic leaching. Leaching e sa khaotseng hangata e amohela mokhoa oa hona joale oa leaching. Haeba ho tla sebelisoa cross - current or counter - current leaching, ts'ebetso ea karohano ea metsi e tiileng e lokela ho eketsoa lipakeng tsa mohato ka mong. Leaching e tsamaisoang ka sehlopha ka kakaretso e sebelisoa ke leaching ea hona joale, empa leaching ea hona joale kapa ea khaontara le eona e ka sebelisoa. Leha ho le joalo, karohano e tiileng-ea metsi ea hlokahala ka mor'a ts'ebetso e 'ngoe le e' ngoe ea leaching, ho etsa hore ts'ebetso e rarahane le hore e se ke ea sebelisoa hangata tlhahisong. Percolation leaching e ka fumana leachate e hlakileng ka kotloloho, athe seretse se tsoang ho leaching e ts'oeroeng se tlameha ho arohana ka metsi ho fumana leachate e hlakileng kapa ho hlapolla seretse se nang le likaroloana tse nyane tsa ore bakeng sa ts'ebetso e latelang.
