Rage amfani da sinadarin Sodium Cyanide a cikin cyanide, masana'antar Carbon -in-pulp ta zama aiki mai gaggawa don inganta ingancin tattalin arziki da kuma kyautata muhallin aikin samarwa. Wannan labarin ya gabatar da sakamakon gwajin samarwa da nufin rage yawan amfani da sinadarin sodium cyanide a cikin masana'antar carbon-in-pulp ta cyanide.

2. Tarihin Matsala

Yawan amfani da sodium cyanide a cikin tsire-tsire na cyanide carbon-in-pulp shuke-shuke shine yafi saboda dalilai da yawa. Da fari dai, kasancewar datti iri-iri a cikin ma'adinan, irin su jan karfe, zinc, da baƙin ƙarfe, na iya amsawa tare da cyanide, wanda ke haifar da amfani da adadi mai yawa na sodium cyanide. Na biyu, rashin kula da yanayin leaching, kamar ƙimar pH, zafin jiki, da ƙimar iska, na iya haifar da ƙara yawan amfani da sodium cyanide. Bugu da ƙari, rashin ingancin kayan aikin leaching da tsarin sake yin amfani da maganin cyanide na iya kara tsananta wannan matsala. Sabili da haka, ya zama dole a gudanar da bincike mai zurfi da bincike don gano ingantattun matakai don rage yawan amfani da sodium cyanide.

Don rage mummunan tasiri na ƙazanta a cikin ma'adinai akan amfani da sodium cyanide, an binciko hanyoyin da aka rigaya. An gwada manyan hanyoyin magancewa guda biyu, wato tuwo da gasassu. Hanyar flotation da nufin raba ma'adanai masu mahimmanci da ƙazanta, yayin da aka yi amfani da hanyar gasa don oxidize ma'adinan sulfide da kuma cire wasu ƙazantattun da za su iya cinye cyanide.

3.4 Inganta Tsarin Sake Amfani da Cyanide

Ingancin tsarin sake amfani da cyanide yana shafar amfani da sodium cyanide kai tsaye. A cikin wannan binciken, an inganta tsarin sake amfani da cyanide. An gabatar da sabbin fasahohi da kayan aiki don haɓaka ƙimar dawowar cyanide daga wutsiya da maganin leaching. Bugu da ƙari, an kula da ingancin maganin cyanide da aka sake yin fa'ida a hankali kuma an daidaita shi don tabbatar da ingantaccen amfani da shi.

4. Sakamako da Tattaunawa

4.1 Tasirin Inganta Yanayin Leaching

Haɓaka yanayin leaching ya sami sakamako na ban mamaki. Ta hanyar daidaita ƙimar pH zuwa kewayon da ya dace (kusan 10 - 11), ƙara yawan zafin jiki zuwa 30 - 35 ° C, da sarrafa yawan iska a 0.5 - 1.0 L / min, yawan amfani da sodium cyanide ya ragu sosai. A lokaci guda, adadin hakar zinare ya kasance karko ko ma ya karu kadan. Wadannan sakamakon sun nuna cewa kulawar da ta dace na yanayin leaching zai iya inganta yadda ya dace tsakanin zinari da cyanide yayin da rage yawan amfani da sodium cyanide mara amfani.

4.2 Sakamako na Maganin Tama

Hanyoyin pretreatment na tama kuma sun nuna tasiri mai kyau. Tsarin flotation pretreatment yadda ya kamata ya raba wasu daga cikin ƙazanta, kamar tagulla da zinc ma'adanai, daga ma'adanin. A sakamakon haka, yawan amfani da sodium cyanide yayin aikin leaching na gaba ya ragu da kusan 20%. Maganin gasasshen, kodayake ƙarin kuzari - yana da ƙarfi, shima yana da tasiri sosai. Bayan gasa, ma'adinan sulfide da ke cikin ma'adinan sun kasance oxidized, kuma yawan amfani da sodium cyanide ya ragu da kusan 30%. Duk da haka, zaɓin hanyar da za a bi da shi ya kamata ya dogara ne akan takamaiman halaye na ma'adinai da kuma la'akari da tattalin arziki da muhalli na shuka.

4.3 Inganta Tsarin Sake Amfani da Cyanide

Inganta tsarin sake yin amfani da cyanide ya ƙara haɓaka ƙimar cyanide. Sabbin fasahohi da kayan aiki sun ba da damar dawo da adadin cyanide daga wutsiya don haɓaka daga ainihin 60% zuwa sama da 80%, kuma an inganta ingancin maganin cyanide da aka sake yin fa'ida. Wannan haɓakawa ba kawai ya rage adadin sabobin sodium cyanide da ake buƙata don samarwa ba amma kuma ya rage tasirin muhalli na fitar da cyanide.

5. Ƙarshe

Ta hanyar wannan gwajin samarwa, an samo matakai masu tasiri da yawa don rage yawan amfani da sodium cyanide a cikin shukar cyanide carbon-in-pulp shuka. Inganta yanayin leaching, pretreating tama, da kuma inganta tsarin sake amfani da cyanide duk na iya taimakawa wajen rage yawan amfani da sodium cyanide. Waɗannan matakan ba za su iya rage farashin samarwa kawai ba amma kuma suna haɓaka aikin muhalli na shuka. Duk da haka, ya kamata a lura cewa aiwatar da waɗannan matakan yana buƙatar yin la'akari da hankali bisa ga ainihin halin da kowace shuka take ciki, la'akari da abubuwa kamar kaddarorin ma'adinai, sikelin samarwa, da yiwuwar tattalin arziki. Bincike na gaba zai iya mayar da hankali kan ci gaba da inganta ingantaccen waɗannan hanyoyin da kuma binciko sababbin fasaha don samun ƙarin raguwa a cikin amfani da sodium cyanide a cikin tsarin cyanide carbon-in-pulp.
