Mehopolo ea Bohlokoa ho Monyeng oa Khauta ka ho Crushing le ho Leaching ka Kolu Meepong ea Khauta

Ho ntša khauta ka ho e sila le ho e phutha ka liqubu ke mokhoa o sebelisoang haholo indastering ea merafo ea khauta . Ho netefatsa hore khauta e fumanoa hape ka katleho le ka mokhoa o tsitsitseng, basebetsi ba lokela ho ela hloko likarolo tse ngata nakong eohle ea ts'ebetso.

1. Tlhahlobo ea Thepa ea Ore

Sebopeho sa liminerale

Ho bohlokoa ho utloisisa boleng ba khauta le liminerale tse amanang le ore. Mohato ona o thusa ho tseba hore na mokhoa oa leaching oa qubu oa sebetsa. Ka mohlala, haeba tšepe e na le liminerale tse ngata tse hanang, ho ka 'na ha hlokahala hore ho etsoe phekolo e eketsehileng.

Kabo ea boholo ba Particle

Ka mor'a ho pshatla, boholo ba likaroloana tsa ore bo tlameha ho ba bo lekanang. Likaroloana tse kholo li ka lebisa ho leaching e sa phethahalang, athe likaroloana tse nyane li ka hlahisa likotlo tse feteletseng, tsa sitisa ho kenella ha tharollo.

2. Mokhoa oa ho senya

Thepa e Hlōlang

Khetha li-crusher tse loketseng, joalo ka li-crushers tsa mohlahare le li-cone. Mechine ena e etselitsoe ho pshatla tšepe ka boholo bo hlokahalang. Mohlala, li-crushers tsa mohlahare li sebetsa hantle bakeng sa ho pshatla ha mantlha, athe li-cone crushers li loketse ho silakanya maemo a bobeli le a thuto e phahameng.

Taolo ea Boholo ba Karolo

Ka tloaelo, boholo ba likaroloana bo lokela ho laoloa pakeng tsa 10 - 30 millimeters. Likaroloana tse kholo li fokotsa sekhahla sa leaching, 'me likaroloana tse fokolang li ka baka mathata ka tharollo ea percolation ka lebaka la ho thehoa ha likotlo.

3. Tokiso ea Libaka tsa Leaching tsa Heap

Khetho ea Sebaka

Khetha sebaka se bataletseng le se sa keneleng metsi bakeng sa qubu ea leaching. Sena se thusa ho thibela ho lutla ha tharollo, ho ka silafatsang tikoloho.

Phekolo ea ho Impermeability

Beha lesela le sa keneleng metsi ho thibela leachate ho kena mobung. Sena se bohlokoa bakeng sa ts'ireletso ea tikoloho le leaching e sebetsang hantle.

4. Kgetho le Tshebediso ya Leaching Agents

Leaching Agents

Tharollo ea sodium cyanide e atisa ho sebelisoa e le sesebelisoa sa ho ntša metsi. Khakanyo ea sodium cyanide e lokela ho laoloa ka thata ka har'a 0.05% - 0.1%. Khakanyo e phahameng e eketsa litšenyehelo, ha khakanyo e tlase e fokotsa sekhahla sa ho ntša metsi.

Taolo ea Boleng ba pH

Boloka boleng ba pH ba tharollo ea leaching pakeng tsa 10 - 11. Sena se thusa ho thibela ho bola ha cyanide, ho netefatsa katleho ea ts'ebetso ea leaching.

5. Lits'ebetso tsa Heap Leaching

Taolo ea Boima ba Heap

Bophahamo ba qubu hangata bo beoa lipakeng tsa 3 - 6 metres. Mokgobo o phahameng haholo o ka sitisa ho kenella ha tharollo, athe qubu e tlase haholo e fokotsa bokgoni ba tlhahiso.

Ho fafatsa ka Matla

Laola matla a ho fafatsa ho 5 - 10 L/m²·h. Ho fafatsa ho feteletseng ho lebisa tahlehelong ea tharollo, ha ho fafatsa ho sa lekaneng ho ama phello ea leaching.

6. Tsamaiso ea Leachate

Leachate Collection

Netefatsa pokello e sebetsang ea leachate ho qoba tahlehelo le tšilafalo ea tikoloho. Sistimi e hlophisitsoeng hantle ea pokello e bohlokoa bakeng sa ho holisa ho khutlisa khauta.

Leachate Recycling

Recycle leachate ho ntlafatsa ho hlaphoheloa ha khauta le ho fokotsa tšebeliso ea reagent. Sena ha se eke feela ho sebetsa hantle empa se boetse se fokotsa litšenyehelo.

7. Ts'ireletso ea Tikoloho

Phekolo ea metsi a litšila

Phekola sehlaseli pele u se ntša ho thibela tšilafalo ea tikoloho. Sena se ka kenyelletsa mekhoa e joalo ka ho na ha lik'hemik'hale le ho sefa.

Ho lahla Mehatla

Lahla mehatla ka nepo ka mor'a leaching ho thibela tšilafalo ea bobeli. Likhetho li kenyelletsa polokelo e bolokehileng ka matangoaneng a li-tailings kapa ts'ebetso e tsoelang pele.

8. Tsamaiso ea Tšireletseho

Tsamaiso ea Cyanide

Cyanide e chefo haholo. Kenya ts'ebetsong mehato e tiileng ea taolo ho thibela ho lutla le chefo. Sena se kenyelletsa polokelo e nepahetseng, ho tšoara le ho tsamaisa cyanide.

Tšireletso ea Basebetsi

Basebelisi ba lokela ho apara lisebelisoa tse nepahetseng tsa ts'ireletso. Koetliso ea kamehla e boetse e hlokahala ho netefatsa ts'ebetso e sireletsehileng.

9. Tlhokomelo ea Lisebelisoa

Tlhahlobo ea Kamehla

Lekola khafetsa ho sila, ho fafatsa le lisebelisoa tse ling ho netefatsa ts'ebetso e tloaelehileng. Sena se thusa ho lemoha mathata a ka bang teng pele a baka tšitiso e kholo.

Ho Lokisa ka Nako

Lokisa liphoso kapele ho qoba tieho ea tlhahiso. Sekepe sa thepa se hlokometsoeng hantle se bohlokoa bakeng sa tlhahiso e tsoelang pele le e sebetsang hantle.

10. Taolo ea Litšenyehelo

Litšenyehelo tsa Reagent

Ntlafatsa ts'ebeliso ea li-reagents ho fokotsa litšenyehelo. Sena se ka kenyelletsa ho lokisa likhakanyo tsa reagent ho ipapisitse le thepa ea ore le liphetho tsa leaching.

Taolo ea Tšebeliso ea Matla

Ntlafatsa ts'ebetso ea ho senya le ho fafatsa ho fokotsa tšebeliso ea matla. Sena ha se fokotse litšenyehelo feela empa hape se kenya letsoho ho ts'oarellang tikoloho.

Qetellong, ho ntšoa ha khauta ka ho e pshatla le ho e phutha ho hloka ho nahanoa ka botlalo ka thepa ea tšepe, liparamente tsa ts'ebetso, tšireletso ea tikoloho le tsamaiso ea polokeho. Ka ho ela hloko lintlha tsena tsa bohlokoa, basebetsi ba ka ntlafatsa sekhahla sa ho hlaphoheloa ha khauta le ho fihlela nts'etsopele e tsitsitseng indastering ea merafo ea khauta.
