I-Sodium hydrosulfide (NaHS)iyaqhubeka nokugcina isidingo esiqhubekayo ezimakethe zezimboni zomhlaba wonke, ikakhulukazi ezinqubweni zokuntanta kwezimayini, ekucutshungulweni kwesikhumba, ekuhlanganisweni kwamakhemikhali, kanye nasekusetshenzisweni kwe-pulp nephepha. Njengenhlanganisela ebalulekile ye-inorganic equkethe isibabule, idlala indima esebenzayo ezinhlelweni zokuhlukanisa nokucubungula ezikhethiwe ezimbonini eziningi.

Imboni Yezimayini Isalokhu Iyindawo Eyinhloko Yokusetshenziswa

Ukusetshenziswa okukhulu kwe-sodium hydrosulfide kuvela emkhakheni wezimayini, lapho isetshenziswa kabanzi njenge-flotation agent ekuzuzeni izinsimbi ezingezona i-ferrous njengethusi, i-lead, ne-zinc ores. Indima yayo ekusebenzeni kwamaminerali e-sulfide kanye nokusebenza kahle kokuhlukanisa yenza kube yi-reagent ebalulekile emisebenzini yokucubungula amaminerali.

Amaqembu okuthenga embonini yezimayini avame ukugxila ku:

• Okuqukethwe kwesulfure okusebenzayo okuhlala njalo
• Ukusebenza okuzinzile ezinhlelweni ze-flotation
• Amazinga okungcola alawulwayo athinta ukukhetha kwamaminerali
• Ukuncibilika okuthembekile kanye nokuziphatha kokusabela ezinhlelweni zamanzi zokucubungula

Lezi zici zithonya ngqo amazinga okubuyiselwa kwe-ore kanye nokusebenza kahle kokucubungula.

Izicelo Zemboni Yesikhumba Zigcina Ukusetshenziswa Okuzinzile

I-Sodium hydrosulfide isetshenziswa nasembonini yesikhumba njenge-ejenti esekelayo yokususa uboya nokufaka i-lime. Iyasiza ekususweni kwezinwele kanye namaprotheni angewona ahlanganisiwe ezigabeni zokuqala zokucubungula isikhumba.

Abathengi kulo mkhakha bavame ukugcizelela:

• Ukusabela kwamakhemikhali okuzinzile kwemiphumela yokususa izinwele njalo
• Ukulawulwa kwephunga elilawulwayo ngesikhathi sokucubungula
• Ukuhambisana nezinhlelo zokushiswa kwesikhumba ezisekelwe ku-lime

Nakuba imithethonqubo yezemvelo kwezinye izifunda iba lukhuni, isidingo sisazinzile emazweni amakhulu akhiqiza isikhumba.

Ukucubungula Amakhemikhali kanye Nezicelo Eziphakathi

Ekukhiqizweni kwamakhemikhali, i-sodium hydrosulfide isetshenziswa njengendlela ephakathi kokwenziwa kwamakhemikhali asekelwe esibabuleni kanye nasezinqubweni ezithile zamakhemikhali ezikhethekile. Izakhiwo zayo zokunciphisa kanye nokunikeza isibabule ziyenza ifaneleke ezinhlelweni zokuphendula ezilawulwayo.

Abasebenzisi bezimboni bavame ukudinga:

• Ukulawula ukuhlushwa okunembile (ngokuvamile izixazululo ezingama-60% noma ezingama-70% kwezohwebo)
• Izimo zokugcina ezizinzile ngenxa yokuzwela kwe-oxidation
• Ukupakisha okuthembekile ukuvimbela ukuvuza nokuwohloka

Izidingo Zokuthutha Nokuphepha Ziba Zibaluleke Kakhulu

Ngenxa yokuthi iyingozi futhi iyazwela ephunga, i-sodium hydrosulfide idinga ukuphathwa okuqinile kanye nezindinganiso zokuthutha. Abathengi bamazwe ngamazwe bagxila kakhulu ku:

• Ukupakisha okuvalwe uphawu nokumelana nokugqwala
• Ukufakwa kwelebula elifanele lezingozi kanye nokuhambisana ne-SDS
• Ukushisa okulawulwayo kanye nomoya ophumayo ngesikhathi sokuthutha
• Ukuhlinzekwa okuzinzile okuvela kubahlinzeki bamakhemikhali abafanelekayo

Lezi zidingo zokusebenza seziba yizici ezibalulekile ekuhlolweni kwabaphakeli, ikakhulukazi ezimakethe zokuthumela kwamanye amazwe e-Afrika, eMpumalanga Ephakathi, nase-Asia Ephakathi.

Umbono Wemakethe

Imakethe yomhlaba wonke ye-sodium hydrosulfide kulindeleke ukuthi ihlale izinzile, isekelwa yisidingo esiqhubekayo esivela emikhakheni yezimayini kanye neyokucubungula izimboni. Ngenkathi imithethonqubo yezemvelo ingathonya amaphethini okusetshenziswa ezindaweni ezithile, indima yayo ebalulekile ekuzuzeni amaminerali iqinisekisa isidingo sesikhathi eside.

Mayelana neShandong Pulisi Chemical Co., Ltd.
