Izvo Zvese - Slime Inokurudzira Cyanidation Maitiro muGoridhe Mining

1. ziviso

Cyanidation inzira inoshandiswa zvakanyanya yekuchera goridhe muindasitiri yezvicherwa. Yakawana mukurumbira nekuda kwemutengo wayo wakaderera uye yakakwira goridhe kudzoreredza mwero. Iyi nzira inogonesa pane - saiti kugadzirwa kwegoridhe, iyo inoderedza zvakanyanya zvipingamupinyi zvakasiyana zvine chekuita nekureba-kutakurwa kwegoridhe. Nekuda kweizvozvo, inobatsira mukuvandudza hupfumi hwemabhizinesi uye kuchengetedza mari. Zvisinei, kushandiswa kwe cyanide, reagent ine muchetura, pamwe chete nekurebesa kuyerera uye kunonoka kuburitsa goridhe kumhanya, zvinoonekwa zvakaipa zve cyanidation nzira. Kuti uenderane zvirinani nemhando dzakasiyana dzegoridhe - inotakura ores, kuwedzera goridhe kudzoreredza, uye kuderedza mutengo, iyo cyanidation yekubvisa goridhe process yave ichienderera mberi kuvandudzwa.

2. Kuvandudzwa kweCyanidation Process

Mumazuva ekutanga e-cyanidation, teknolojia yekugadzira mineral yakanga isina kunyatsogadzirwa, uye mari yekukuya yakanaka ye ores yakanga yakakwirira. Uyezve, panguva iyoyo, nzira dzekuramba dzichibuda, kudzikisa mvura, uye kusefa kwezvimedu zvakakura zvesimbi yakanga isati yagadzirwa. Naizvozvo, padanho rekutanga rekuvandudzwa kweiyo cyanidation nzira, percolation leaching yaive nzira huru. Percolation leaching yaingokodzera kurapa coarse - grained ores. Zvaida kuti pasave nevhu, marara, kana zvimwe zvisina kuchena mumidziyo yacho. Saka, kusati kwaita leaching, maorivhi akapwanyika aifanira kuiswa, iyo yaiva nzira yekugeza, kuparadzanisa slime. Izvo zvakakasharara - slime zvigadzirwa zvakaiswa muleaching matangi ekurapa cyanidation ne percolation leaching.

Nekuvandudzwa kwemidziyo yehydrometallurgical, senge kuenderera mberi kwekusimudzira matangi ekuvhundutsa, mafirita, makobvu, nezvimwe, mukuwedzera pakushandisa percolation leaching yejecha re ore, zvigadzirwa zvakapatsanurwa zve slime zvinogona kuvezwa mumatangi ekuvhundutsa. Nekufambira mberi uye nekuvandudzwa kwekukuya, kuisa pfungwa, uye kusefa tekinoroji, cyanide leaching yachinja pakubvisa goridhe kubva kune yakatsetseka - yakavezwa goridhe ores. Zvicherwa zvese zvinogayiwa zvakanaka uye zvobva zvanyudzwa mumatangi ane mhirizhonga. Iyi nzira inonzi "all - slime cyanidation" nzira. Iyo ine mabhenefiti ehupamhi hwekudzoreredza, kukurumidza goridhe leaching kumhanya, uye pfupi goridhe kudhirowa kutenderera, saka yakakurumidza kusimudzirwa uye kushandiswa.

3. Kukurudzira Cyanidation Technology uye Yayo Inobatsira Leaching Maitiro

Mumazuva ekutanga eiyo goridhe cyanidation process uchishandisa inosimudzira cyanidation nzira, mhepo inoputika yaishandiswa kuita oxidize goridhe. Gare gare, nekuvandudzwa kwesainzi kwekuchera goridhe uye kuwedzera kunzwisisa kwevanhu kukosha kweokisijeni muLeaching, nzira dzekubatsira leaching dzakadai seokisijeni - yakafumisa leaching uye mvura - phase oxidant - inobatsira leaching yabuda. Izvi zvinosanganisira hydrogen peroxide kana potassium permanganate - inobatsira leaching, ammonia - cyanide - inobatsira leaching, kupisa uye kudzvinyirira - inobatsira leaching, uye lead nitrate - inobatsira leaching.

Okisijeni - yakafumiswa leaching inogona kuwedzera kuwanda kweokisijeni mu leaching system, iyo inosimudzira oxidation yegoridhe uye inovandudza leaching inoshanda. Hydrogen peroxide uye potassium permanganate, semaoxidants akasimba, anogona kukurumidza kukwirisa oxidation yegoridhe muore, nekudaro ichiwedzera kukurumidza kudonha. Ammonia - cyanide - inobatsira leaching inogona kushandura makemikari nharaunda yemushonga weleaching, uyo unobatsira pakuparara kwegoridhe. Kupisa uye kudzvanywa - kunobatsira leaching kunogona kuwedzera chiyero chekuita nekuvandudza tembiricha uye kudzvanywa mamiriro, nepo lead nitrate - inobatsirwa leaching inogona kuita basa rinoita mukuita kwe cyanidation yegoridhe.

4. Matambudziko Neramangwana

Kunyangwe zvakanakira, iyo yese - slime inosimudzira cyanidation process ichiri kutarisana nemamwe matambudziko. Kushandiswa kwecyanide ine muchetura zvakanyanya kunoda matanho ekuchengetedza akasimba uye manejimendi ekuchengetedza kwezvakatipoteredza kudzivirira kubuda kwecyanide uye kusvibiswa. Kushanda kwenguva refu kwemaitiro kunodawo huwandu hukuru hwekushandisa simba.

Mune ramangwana, kutsvagisa uye kusimukira mundima iyi kuchatarisa pakugadzira nzira dzakasarudzika uye dzinoshanda dzekuchera goridhe. Izvi zvinogona kusanganisira kuongorora mamwe asiri -cyanide leaching agents kuti atsive cyanide, kuvandudza kushanda kwemaitiro aripo ekudzikisa mashandisirwo emagetsi, uye nekuwedzera optimize michina uye mafambiro ekuyerera kuti awedzere kuita kwese kwekutorwa kwegoridhe. Pamusoro pezvo, nekuenderera mberi kwekuvandudza tekinoroji uye nehungwaru matekinoroji, mashandisirwo ematekinoroji aya mune zvese - slime inosimudzira cyanidation process inogona zvakare kuunza mikana mitsva yekuvandudza hunyanzvi hwekugadzira uye kuderedza mutengo wevashandi.

Mukupedzisa, iyo yose - slime inosimudzira cyanidation process yakaita basa rakakosha muindasitiri yemigodhi yegoridhe. Kunyangwe iine zvimwe zvayakaipira, kuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji kuchaibatsira kuti ienderane nezvinodiwa zvebudiriro zveindasitiri uye kubatsira mukusimudzira indasitiri yemigodhi yegoridhe.
