Ukusetshenziswa kwe-CMC Embonini Yezimayini

I-Carboxymethylcellulose (CMC) ithola ukusetshenziswa embonini yezimayini ngenxa yezakhiwo zayo ezihlukile njenge-polymer encibilikayo emanzini. Ukuguquguquka kwe-CMC kuyenza ibe usizo ezinqubweni ezahlukahlukene ngaphakathi komkhakha wezimayini. Nazi izindlela eziningana zokusebenzisa i-CMC embonini yezimayini:

1. Ukufakwa Kwensimbi Eyigugu:

• I-CMC isetshenziswa ezinqubweni zokufaka i-ore pelletization. Isebenza njengesihlanganisi, inegalelo ekuhlanganisweni kwezinhlayiya ezincane ze-ore zibe ama-pellet. Le nqubo ibalulekile ekukhiqizweni kwama-pellet e-iron ore asetshenziswa ezithandweni zokuqhuma.

2. Ukulawula Uthuli:

• I-CMC isetshenziswa njengesivimbeli sothuli emisebenzini yezimayini. Uma isetshenziswa ezindaweni zamaminerali, isiza ukulawula ukukhiqizwa kothuli, idale indawo yokusebenza ephephile futhi inciphise umthelela wemisebenzi yezimayini endaweni ezungezile.

3. Ukwelashwa Kwemisila Nokudakwa:

• Ekwelapheni ama-tailings nama-slurry, i-CMC isetshenziswa njenge-flocculant. Isiza ekuhlukaniseni izinhlayiya eziqinile koketshezi, okwenza kube lula inqubo yokukhipha amanzi. Lokhu kubalulekile ekulahleni ama-tailings ngempumelelo kanye nokubuyisa amanzi.

4. Ukuvuselelwa Kwamafutha Okuthuthukisiwe (i-EOR):

• I-CMC isetshenziswa kwezinye izindlela zokubuyisa uwoyela ezithuthukisiwe embonini yezimayini. Ingaba yingxenye yoketshezi olufakwa ezinqolobaneni zikawoyela ukuze kuthuthukiswe ukufuduka kukawoyela, okunegalelo ekwandiseni ukubuyisa uwoyela.

5. Ukubhoboza Umhubhe:

• I-CMC ingasetshenziswa njengengxenye yoketshezi lokubhoboza imisele. Isiza ekuqiniseni uketshezi lokubhoboza, ilawule ukujiya, futhi isize ekususweni kwezicucu ngesikhathi senqubo yokubhoboza.

6. Ukuntanta Kwamaminerali:

• Enqubweni yokuntanta kwamaminerali, esetshenziselwa ukuhlukanisa amaminerali abalulekile ku-ore, i-CMC isetshenziswa njengesidambisi-zinhlungu. Ivimbela ngokukhetha ukuntanta kwamaminerali athile, isiza ekuhlukaniseni amaminerali abalulekile ku-gangue.

7. Ukucaciswa Kwamanzi:

• I-CMC isetshenziswa ezinqubweni zokucacisa amanzi ezihambisana nemisebenzi yezimayini. Njenge-flocculant, ikhuthaza ukuhlangana kwezinhlayiya ezilenga emanzini, okwenza kube lula ukuzinza nokuhlukana kwazo.

8. Ukulawulwa Kokuguguleka Komhlabathi:

• I-CMC ingasetshenziswa ekulawulweni kokuguguleka kwenhlabathi okuhlobene nezindawo zokumba. Ngokwakha isithiyo esivikelayo ebusweni benhlabathi, kusiza ekuvimbeleni ukuguguleka kanye nokugeleza kwendle, kugcina ubuqotho bezinto eziphilayo ezizungezile.

9. Ukuqina Kwemigodi:

• Emisebenzini yokubhoboza, i-CMC isetshenziselwa ukuqinisa imigodi yamanzi. Isiza ukulawula ukwakheka kwamanzi okugcoba, ivimbele ukubhidlika kwemigodi yamanzi kanye nokuqinisekisa ukuqina kwemigodi ebhoboziwe.

10. Ukususa Ubuthi Nge-Cyanide: – Ekumbiweni kwegolide, i-CMC ngezinye izikhathi isetshenziswa ekususeni ubuthi emfucumfucwini equkethe i-cyanide. Ingasiza enkambisweni yokwelapha ngokwenza kube lula ukuhlukaniswa nokususwa kwe-cyanide esele.

11. Ukugcwalisa Imigodi Emayini: – I-CMC ingasetshenziswa enqubweni yokugcwalisa imigodi ezimayini. Isiza ekuzinzeni nasekuhlanganeni kwezinto zokugcwalisa imigodi, iqinisekisa ukugcwaliswa okuphephile nokulawulwayo kwezindawo ezichithwe emayini.

12. Ukusetshenziswa kwe-Shotcrete: – Ekuvulweni kwemihubhe kanye nasekumbiweni komhlaba, i-CMC isetshenziswa ekusetshenzisweni kwe-shotcrete. Ithuthukisa ukuhlangana kanye nokunamathela kwe-shotcrete, okufaka isandla ekuzinzeni kwezindonga zemihubhe kanye nezindawo ezimbiwe.

Ngamafuphi, i-carboxymethylcellulose (CMC) idlala indima ehlukahlukene embonini yezimayini, ifaka isandla ezinqubweni ezifana nokufakwa kwe-ore pelletization, ukulawulwa kothuli, ukwelashwa kwe-tailings, nokuningi. Izakhiwo zayo ezincibilika emanzini kanye ne-rheological ziyenza ibe yisithako esibalulekile ekusetshenzisweni okuhlobene nokumba, ibhekane nezinselele futhi ithuthukise ukusebenza kahle kanye nokusimama kwemisebenzi yokumba.
