Mafungiro Akakosha muKuchera Goridhe kuburikidza neKupwanya uye Murwi Leaching muMigodhi yeGoridhe

Kuburitsa goridhe kuburikidza nekupwanya nekukwesha goridhe inzira inoshandiswa zvakanyanya muindasitiri yekuchera goridhe . Kuti goridhe ridzorerwe zvakanaka uye nenzira inogara kwenguva refu, vashandi vanofanirwa kunyatsotarisa zvinhu zvakawanda mukati mekuita uku.

1. Kuongororwa kweOre Properties

Mineral Composition

Kunzwisisa zvirimo zvegoridhe uye zvicherwa zvinosanganisirwa muore kwakakosha. Danho iri rinobatsira kuona kuti nzira yekugadzira murwi inoshanda here. Semuyenzaniso, kana simbi yacho iine huwandu hukuru hwemaminerari asingadzoreki, kumwe kutarisisa kunogona kudiwa.

Particle Size Distribution

Mushure mekupwanya, chiyero chechidimbu cheore chinofanira kunge chakafanana. Oversized zvimedu zvinogona kutungamira kune isina kukwana leaching, nepo undersized zvimedu zvinogona kuburitsa faindi yakawandisa, zvichitadzisa mhinduro kupinda.

2. Crushing Process

Crushing Equipment

Sarudza macrusher akakodzera, akadai seanopwanya shaya uye cone crushers. Michina iyi yakagadzirirwa kupwanya simbi kusvika pakukura kunodiwa. Semuyenzaniso, shaya dzinopwanya dzinoshanda pakupwanya kwekutanga, ukuwo macone crushers akakodzera kusecondary netertiary kupwanya.

Particle Saizi Kudzora

Kazhinji, saizi yepakati inofanira kudzorwa pakati pe10 - 30 millimeters. Oversized zvimedu zvinoderedza chiyero cheleaching, uye zvidimbu zvidiki zvinogona kukonzera nyaya nemhinduro percolation nekuda kwekuumbwa kwefaindi.

3. Gadziriro Yenzvimbo dzeMurwi Leaching

Sarudzo yeSiti

Sarudza nzvimbo yakati sandara uye isingapindiki kuitira murwi wekucheka. Izvi zvinobatsira kudzivirira kubuda kwemhinduro, izvo zvinogona kusvibisa nharaunda.

Impermeability Kurapa

Isa membrane isingapindiki kudzivirira leachate kuti isapinda muvhu. Izvi zvakakosha pakuchengetedzwa kwezvakatipoteredza uye leaching inoshanda.

4. Kusarudzwa uye Kushandiswa kweLeaching Agents

Leaching Agents

Mushonga weSodium cyanide unowanzo shandiswa senzira yekuburitsa mvura. Kuwanda kweSodium cyanide kunofanira kudzorwa zviri mukati me0.05% - 0.1%. Kuwanda kwakanyanya kunowedzera mitengo, nepo kuwanda kwakaderera kunoderedza mwero wekuburitsa mvura.

pH Kukosha Kudzora

Chengetedza pH kukosha kwekugadzirisa kwekugadzirisa pakati pe 10 - 11. Izvi zvinobatsira kudzivirira kuparara kwe cyanide, kuve nechokwadi chekushanda kwekugadzirisa.

5. Murwi Leaching Operations

Murwi Urefu Kudzora

Kureba kwemurwi kunowanzoiswa pakati pe3 - 6 metres. Murwi wakanyanya kukwirisa unogona kukanganisa kupinda kwemhinduro, nepo murwi wakadzikira zvakanyanya unoderedza kugona kwekugadzira.

Spraying Intensity

Dzora simba rekupfapfaidza pa5 - 10 L/m²·h. Kupfapfaidza kwakawandisa kunotungamira mukurasikirwa kwemhinduro, nepo kusapfapfaidza kwakakwana kunokanganisa maitiro ekuita leaching.

6. Kutungamira kweLeachate

Leachate Collection

Ita shuwa kuunganidzwa kwakanaka kweleachate kudzivirira kurasikirwa uye kusvibiswa kwezvakatipoteredza. Iyo yakanyatso gadzirwa kuunganidza sisitimu yakakosha pakuwedzera kudzoreredza goridhe.

Leachate Recycling

Dzokorora iyo leachate kuvandudza goridhe kudzoreredza uye kuderedza reagent kushandiswa. Izvi hazvisi kungowedzera kushanda zvakanaka asiwo zvinoderedza mari.

7. Kudzivirirwa kwezvakatipoteredza

Kuchenesa mvura

Ropa tsvina usati waibvisa kudzivirira kusvibiswa kwezvakatipoteredza. Izvi zvinogona kusanganisira maitiro akadai sekunaya kwemakemikari uye kusefa.

Tailings Disposal

Rasa maswe zvakanaka mushure mekudonha kudzivirira kusvibiswa kwechipiri. Sarudzo dzinosanganisira kuchengetedza kwakachengeteka mumadziva ekumisa kana kuenderera mberi nekugadzirisa.

8. Kuchengetedzwa Kwekuchengetedza

Cyanide Management

Cyanide ine chepfu zvakanyanya. Ita matanho akasimba ekutarisira kudzivirira kuvuza uye chepfu. Izvi zvinosanganisira kuchengetedza kwakakodzera, kubata, uye kutakura cyanide.

Kudzivirirwa Kwevashandi

Vashandi vanofanira kupfeka midziyo yekudzivirira yakakodzera. Kudzidzira nguva dzose kunodiwawo kuti uve nechokwadi chekushanda kwakachengeteka.

9. Kugadziriswa Kwemidziyo

Kuongorora Nguva Dzose

Gara uchiongorora kupwanya, kupfapfaidza, uye zvimwe midziyo kuti uone kushanda kwakajairika. Izvi zvinobatsira kuziva zvingangoitika matambudziko asati akonzera kukanganisa kukuru.

Kugadzirisa Nenguva

Gadzirisa chero kukanganisa nekukasika kudzivirira kunonoka kugadzira. Chikepe chemidziyo inochengetedzwa zvakanaka chakakosha pakuenderera uye kugadzirwa kwakanaka.

10. Kudzora Mutengo

Reagent Cost

Gadzirisa kushandiswa kwemareagents kuderedza mari. Izvi zvinogona kusanganisira kugadzirisa reagent kutariswa kwakavakirwa pane ore zvivakwa uye leaching mhedzisiro.

Energy Consumption Control

Gadzirisa maitiro ekupwanya uye kupfapfaidza kuderedza kushandiswa kwesimba. Izvi hazvingodzikisi mari chete asiwo zvinobatsira mukuchengetedzeka kwezvakatipoteredza.

Mukupedzisa, kuburitsa goridhe kuburikidza nekupwanya nekukwesha goridhe kunoda kutariswa kwakazara kwehunhu hwematombo, maitiro ekugadzira, kuchengetedzwa kwezvakatipoteredza, uye manejimendi ekuchengetedza. Nekuteerera zvinhu izvi zvakakosha, vanoshanda vanogona kuvandudza mwero wekudzoserwa kwegoridhe uye kuwana budiriro inoenderera mberi muindasitiri yekuchera goridhe.
