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

Jinchan inochengetedza magariro egoridhe leaching agent yakashandiswa mumaindasitiri paWenyu Gold Mine kuLingbao, Henan Province, kunyanya pakuchera zvinhu zvakakosha segoridhe. Chirongwa ichi chine goridhe rine magiramu mapfumbamwe patani uye an Inorganic carbon zvikamu zve10.94%. Mukana wakakura wepurojekiti iyi kutevedzera kwezvakatipoteredza, kusanganisira kushandisa Jinchan eco-inoshamwaridzika goridhe leaching agent sechinotsiva. Sodium Cyanide. Iyi nzira haingovimbisi kukwirira kwepamusoro Kuchera goridhe asi zvakare inoderedza kukanganisa kwezvakatipoteredza kweiyo ore process process.

Kana hunyoro hwekugaya huri -0.074 mm, ine zviri mukati kupfuura 90%, pulp concentration ye40%, lime dosage ye3 kg/t, alkaline pretreatment yemaawa maviri, Jinchan eco-inoshamwaridzika goridhe leaching agent dosage ye2 g/t, uye nguva yekubuda yemaawa makumi maviri nemana. Leaching rate inogona kusvika 95.60%. Kana ichienzaniswa necyanide leaching, mwero wekubuda ropa unowedzera ne1.4%, kushandiswa kwe reagent kunodzikira ne200 g/ton, uye nguva yeleaching inopfupikiswa neanopfuura maawa gumi nemaviri. Uyezve, kudonha Kuongororwa kwehuturu yeJinchan eco-inoshamwaridzika goridhe leaching agent yakasara yakaratidza kuti leaching toxicity kukosha kwecyanide, mhangura, lead, zinc, uye arsenic mumisara zvese zviri mukati meiyo yenyika miganho uye inogona kuburitswa yakananga pasina kudiwa kwekubvisa.

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 kwesodium cyanide neJinchan eco-inoshamwaridzika goridhe leaching agent inoratidza kuzvipira kwemugodhi Kuchengetedzwa kwemagariro. Sodium cyanide yagara iri iyo indasitiri chiyero chegoridhe leaching, asi muchetura wayo unoisa njodzi dzakakura kunharaunda uye hutano hwevanhu. Kusiyana neizvi, mumiriri weJinchan anopa imwe nzira yakachengeteka uye yakagadzikana, kuve nechokwadi chekuti nzira yekubvisa goridhe haiuye nekukanganisa kwezvakatipoteredza. Kuchinja uku kuenda kune eco-hushamwari maitiro kunobatsira ecosystem yemuno uye inogadza muenzaniso wakanaka kune yakakura indasitiri yezvicherwa.

Iyo yakazara-lime cyanidation chirongwa paWenyu Gold Mine chiitiko chakakosha kukambani yedu mukutanga mugodhi usina cyanide. Ichi chirongwa chinosimbisa maitiro ekuchengetedza kwezvakatipoteredza, tichishandisa tekinoroji nyowani seJinchan eco-inoshamwaridzika goridhe leaching agent, inotungamira kune yakagadzikana uye ine mutoro nzira dzegoridhe ore. Wenyu Gold Mine inoratidza kuti zvinhu zvakakosha zvakaita segoridhe zvinokwanisa kuburitswa pasina kukuvadza nharaunda, kumisa mwero mutsva weindasitiri. Chirongwa ichi chinoratidza izvozvo Migodhi ine mutoro maitiro uye kutonga kwezvakatipoteredza zvinogona kufambidzana, zvichigadzira nzira yeramangwana rakagadzikana mumigodhi.
