Kutora Goridhe kubva kuOxidized Gold Ore

Muchisikigo, goridhe harisangani neokisijeni kuumba maokisidhi sesimbi kana mhangura. Angave akavigwa mumakuva, mujecha, kana kuti akazorora pasi pegungwa kwezviuru zvemakore, zvigure zvendarama, zviyo, uye mazariro zvinoramba zvichipenya zvakajeka.

Saka, kana goridhe isingaite oxidize, chii chaizvo oxidized gold ore?

Kunzwisisa Oxidized Gold Ores

Oxidized goridhe ore inoreva goridhe - inotakura ore inoumbwa kuburikidza neakasikwa oxidation maitiro, kwete egoridhe oxides.

Ores akadaro anowanzo kuve negoridhe pamwe chete nemaokisi esimbi sesimbi, mhangura, uye manganese. Iwo maminerari makuru arimonite uye pyrite, ane mashoma kana asina sulfides, asi anosanganisira akagadzikana echipiri zvicherwa segoridhe - inotakura iron hydroxides kana hydrated iron oxides, pamwe neimwe quartz.

Mamiriro ekunze ekunze anoshandura maminerari esulfide kuita maokisidhi uye mahydroxide, negoridhe rinogona kuiswa muhematite, goethite, kana limonite.

Oxidized ore yegoridhe inowanzoita yero kusvika kune brown uye ine yakasununguka manyorerwo. Chinhu chakakosha mbishi kugadzirwa kwegoridhe.

Nzira yekubvisa Goridhe kubva kuOxidized Gold Ore?

Mune oxidized goridhe ore, yakawanda yegoridhe iri mukati meiyo huru gangue zvicherwa uye kutsemuka kweakaomeswa nesimbi oxides. Iyo yegoridhe particle size inosiyana zvakanyanya, uye mamineral kuumbwa kuri nyore.

Usati watanga kupwanya nekukuya maitiro, kufanogadzirisa goridhe ne trommel skrini inhanho yakakosha yekuvandudza kugona kwekubatsira, kunyanya kune oxidized goridhe ores ine ivhu.

Zvadaro, kutorwa kwegoridhe inogona kuitwa uchishandisa nzira dzakadai se kupatsanurwa kwegiravhiti, cyanidation, kana murwi leaching.

Danho 1: Ore Kupwanya

Kupwanya kunoderedza saizi yeoxidized ore yegoridhe uye kunowanzo itwa uchishandisa yakaoma maitiro ane maviri kusvika matatu akateedzana ekupwanya matanho: yekutanga, yechipiri, uye yepamusoro.

Mushure mekupwanya, chidzitiro chinozunguza chinoshandiswa kurongedza oxidized goridhe ore. Zvidiki zvidiki zvinopfuura nepamazarurwa escreen ukuwo zvimedu zvakakura zvichisara pachiratidziro uye zvinodzoserwa kuti zvipwanyirwe zvakare.

Danho 2: Ore Kukuya

Kukuya kunoburitsa goridhe kubva kumaminerari e gangue mune oxidized ore yegoridhe, zvichigadzira mamiriro akanaka ekuzozobatsirwa. Midziyo yekukuya yakajairika inosanganisira zvigayo zvebhora uye zvigayo zvepani zvakanyorova.

Nhanho 3: Ore Beneficiation

Oxidized goridhe ore beneficiation inzira yakaoma uye yakaoma. Maitiro ekubvisa akasiyana anogona kusarudzwa zvichienderana nemhando yeore uye chimiro chegoridhe. Izvi zvinotevera nzira dzinoverengeka dzinozivikanwa dzekubatsirikana:

1. Gravity Separation

Gravity separation inzira yemuviri inoshandisa mutsauko mune chaiyo giravhiti pakati pegoridhe ore uye gangue minerals yekuparadzanisa.

Inowanzo shandiswa oxidized goridhe ore giravhiti yekuparadzanisa michina inosanganisira kuzunguza tafura, spiral chute, jig, nezvimwe.

2. Cyanidation

Nzira yecyanidation ndiyo inonyanya kushandiswa kemikari nzira yekuchera goridhe. Yakakodzera kucherwa kudiki nepakati-kucherwa kweoxidized ores yegoridhe, kunyanya iyo ine yakanaka particle size uye yakakwirira giredhi.

Mushure mekugaya, iyo oxidized ore yegoridhe inosanganiswa nayo cyanide mhinduro, uye goridhe rinonyungudutswa mumvura kuburikidza neleaching reaction, uye ipapo goridhe rinodzoserwa ne activated carbon adsorption kana zinc precipitation.

Cyanidation inopa yakakwira goridhe kudzoreredza mareti uye kushanda kwakafara asi inosanganisira mashandiro akaomarara uye mitengo yakakwira nekuda kwekudiwa kwekubata tsvina yecyanide.

3. Murwi Leaching

Heap leaching inokodzera yakaderera - giredhi kana machunks makuru egoridhe oxidized ore, kazhinji pasina kusati kwakuya.

Mushure mekupwanywa, ore yegoridhe inoturikidzwa painovuza - proof heap leaching pad, kuita murwi weore. Cyanide solution inopfapfaidzwa pamusoro pemurwi kuti inyungudise goridhe, rinobva radzoserwa kubva mumushonga weleach.

Iyi nzira ine mutengo wakaderera wekudyara, mashandiro ari nyore, kuchinjika kwakafara, uye akakodzera hukuru - kutorwa kweiyo yakaderera-giredhi goridhe ores. Nekudaro, inoda chaiyo ore particle size, sezvo yakanyanya kunaka zvimedu zvingakanganisa leaching kushanda zvakanaka.

Idzi ndidzo nzira nhatu huru dzekugadzirisa oxidized goridhe ore. Kune zvishoma oxidized ores, giravhiti kupatsanurwa uye cyanidation zvinowanzobatanidzwa. Mune ore yakazadzwa neoxidized, goridhe rakakasharara rinonyanya kudzoserwa uchishandisa giravhiti kupatsanurwa, nepo zvimedu zvegoridhe zvakanakisa zvinogadziriswa neagitation cyanidation, uye jecha - saizi zvidimbu zvinogadziriswa ne percolation cyanidation.

mhedziso

Kugadziriswa kweoxidized ore yegoridhe zvinoenderana nechimiro cheore uye chimiro chegoridhe. Nekusarudza nzira dzakanyatsokodzera dzekubatsirikana uye nekunatsiridza kupwanya, kukuya, uye kupatsanurwa, mitengo yekudzoreredza goridhe inogona kukwidziridzwa uye mabhenefiti ehupfumi anovandudzwa.

Shanxi United Chemical inogadzira zvemhando yepamusoro Sodium cyanide kuburikidza nehunyanzvi hwepamusoro uye michina. Pamibvunzo yehunyanzvi ine chekuita negoridhe ore cyanidation, murwi leaching, nezvimwe, unogona kutibvunza chero nguva. Isu tinobatsira vatengi kuwana yakanyatsoshanda uye yakagadzikana kudzoreredza goridhe.
