United Chemical, TuXingSun Mining, uye Henan Lingbao Goridhe Mugodhi Vakabatana Vakagadzira Mugodhi Usina Cyanide

Mushonga wekubvisa goridhe weJinchan usingakuvadzi nharaunda wakashandiswa mumaindasitiri kuWenyu Gold Mine muLingbao, Henan Province, kunyanya pakubvisa zvinhu zvinokosha zvakaita segoridhe. Chirongwa ichi chine huwandu hwegoridhe hwe9 gramu patani uye huwandu hwekabhoni husina kugadzirwa hwe10.94%. Chinhu chikuru chechirongwa ichi ndechekutevedzera nharaunda, kusanganisira kushandisa mushonga wekubvisa goridhe weJinchan usingakuvadzi nharaunda panzvimbo yeSodium Cyanide . Nzira iyi haingovimbisi chete kuti kuburitsa goridhe kunoshanda zvakanyanya asiwo inoderedza kukanganisa kwenzvimbo kwemaitiro ekugadzirisa matombo.

Kana kukora kwemuchina kuri -0.074 mm, nehukuru hunopfuura 90%, huwandu hwepulp hwe40%, chiyero che lime che 3 kg/t, nguva yekurapa kwealkaline yemaawa maviri, chiyero che Jinchan gold leaching agent chinochengetedza nharaunda che 600 g/t, uye nguva yekubvisa yeawa makumi maviri nemana, chiyero che gold Leaching chinogona kusvika 95.60%. Zvichienzaniswa ne cyanide leaching, chiyero chekubvisa yeawa chinowedzera ne1.4%, kushandiswa kwe reagent kunoderera ne200 g/ton, uye nguva yekubvisa yeawa inopfupikiswa neanopfuura maawa gumi nemaviri. Uyezve, kuongorora Toxicity ye Jinchan gold leaching agent's residue kwakaratidza kuti hunhu hwechepfu hwekubvisa yeawa yecyanide, copper, lead, zinc, uye arsenic mu tailings zvese zviri mukati memiganhu yenyika uye zvinogona kuburitswa zvakananga pasina chikonzero chekubvisa chepfu.

Chinhu chakakosha mukuyedzwa kwakabudirira kweiyo yakazara-lime cyanidation chirongwa ndiko kushandiswa kweJinchan eco-inoshamwaridzika goridhe leaching agent. Iyi leaching agent yakanyatsogadzirirwa kufambisa iyo leaching uye kunyura maitiro zvine mwero. Iyo Jinchan leaching agent inoshandisa mana-nhanho leaching uye mashanu-nhanho yekunyudza maitiro, kuve nechokwadi chekuti kunyangwe nekuvapo kweinorganic kabhoni, iyo goridhe leaching maitiro haikanganisike. Uku budiriro yakakosha yeprojekiti, sezvo inoratidza kuti eco-hushamwari dzimwe nzira dzinogona kushanda semaitiro echinyakare. Kuenzaniswa necyanide leaching, chiyero cheleaching chinogona kuvandudzwa ne1.4%, kushandiswa kwemareagents kunoderedzwa ne200 magiramu patani, uye nguva yeleaching inopfupikiswa neanopfuura maawa gumi nemaviri, zvichikonzera mhedzisiro yakanaka yeleaching uye zvakakosha zvehupfumi.

Kutsiviwa kwe sodium cyanide ne Jinchan gold leaching agent inochengetedza nharaunda kunoratidza kuzvipira kwemugodhi kuchengetedza nharaunda . Sodium cyanide yagara iriyo nzira inoshandiswa muindasitiri ye leaching yegoridhe, asi chepfu yayo inokonzera njodzi huru kunharaunda nehutano hwevanhu. Kusiyana neizvi, Jinchan agent inopa imwe nzira yakachengeteka uye inogara kwenguva refu, ichivimbisa kuti nzira yekubvisa goridhe haiuye nekukanganisa nharaunda. Kuchinja uku kuenda kutsika dzinochengetedza nharaunda kunobatsira nharaunda yemuno uye kunopa muenzaniso wakanaka kuindasitiri yemigodhi yakakura.

Chirongwa chekugadzira goridhe rakazara paWenyu Gold Mine chiitiko chakakosha kukambani yedu mukugadzira mugodhi usina cyanide. Chirongwa ichi chinosimbisa nzira dzekuchengetedza nharaunda, uchishandisa matekinoroji matsva akadai seJinchan gold leaching agent inochengetedza nharaunda, zvichitungamira kune nzira dzekugadzirisa goridhe dzakasimba uye dzine mutoro. Wenyu Gold Mine inoratidza kuti zvinhu zvakakosha zvakaita segoridhe zvinogona kutorwa zvinobudirira pasina kukuvadza nharaunda, zvichiisa mwero mutsva weindasitiri. Chirongwa ichi chinoratidza kuti nzira dzekuchera dzine mutoro uye manejimendi ezvakatipoteredza zvinogona kufamba pamwe chete, zvichigadzira nzira yeramangwana rinogara kwenguva refu mukuchera.
