Isesengura rigufi ry'uruhare rwa sulfate y'umuringa mu nyungu z'amabuye y'agaciro no guhindagurika

Sulfate y'umuringa, igaragara nk'ubururu cyangwa ubururu-icyatsi kibisi, ni igikoresho gikoreshwa cyane mu gucukura amabuye ya sulfide.Ikoreshwa cyane cyane nka activateur, igenzura na inhibitor kugirango ihindure pH agaciro ka slurry, igenzure kubyara ifuro kandi itezimbere Ubushobozi bwubutaka bwamabuye y'agaciro bugira ingaruka yibikorwa kuri sphalerite, stibnite, pyrite na pyrrotite, cyane cyane sphalerite ihagarikwa na lime. cyangwa cyanide.

Uruhare rwa sulfate y'umuringa mu guhinduranya amabuye y'agaciro:

1. Ikoreshwa nka activate

Irashobora guhindura imiterere yumuriro wubutaka kandi igakora minerval hydrophilique.Iyi hydrophilicity irashobora kongera aho ihurira hagati yubutare n’amazi, bigatuma byoroha minerval kureremba.Sulfate y'umuringa irashobora kandi gukora cations mu myunyu ngugu, ibyo bikaba byongewe hejuru hejuru y’amabuye y'agaciro, bikongera hydrophilique na buoyancy.

Uburyo bwo gukora bukubiyemo ibintu bibiri bikurikira:

①.Metathesis reaction ibaho hejuru yubutare bukora kugirango ikore firime.Kurugero, sulfate y'umuringa ikoreshwa mugukora sphalerite.Iradiyo ya ion y'umuringa ihwanye isa na radiyo ya zinc ion, kandi gukomera kwa sulfide y'umuringa ni bito cyane ugereranije na zinc sulfide.Kubwibyo, firime ya sulfide y'umuringa irashobora gukorwa hejuru ya sphalerite.Nyuma yo gukora firime ya sulfide y'umuringa, irashobora gukorana byoroshye nuwakusanyije xanthate, kugirango sphalerite ikore.

②.Kuraho inhibitor banza, hanyuma ukore firime ya activation.Iyo sodium cyanide ibuza sphalerite, ion zinc cyanide ion zikora hejuru ya sphalerite, kandi ion cyanide y'umuringa iba ihagaze neza kuruta ion zanide.Niba sulfate y'umuringa yongewemo muri sphalerite slurry ihagarikwa na cyanide, radicals ya cyanide hejuru ya sphalerite izagwa, kandi ion z'umuringa wubusa zizakorana na sphalerite kugirango zikore firime ikora ya sulfide y'umuringa, bityo ikore. sphalerite.

2. Ikoreshwa nkumuyobozi

PH agaciro ka slurry irashobora guhinduka.Ku giciro gikwiye cya pH, sulfate y'umuringa irashobora kwitwara hamwe na ion ion ya hydrogène hejuru yubutaka kugirango habeho ibintu bya chimique bihuza nubutaka bwamabuye y'agaciro, byongera hydrophilicity na buoyancy ya minerval, bityo bigatera ingaruka za flotation yibirombe bya zahabu.

3. Ikoreshwa nka inhibitor

Intungamubiri zirashobora gushingwa muburyo bworoshye kandi zigashyirwa hejuru yandi mabuye y'agaciro adakenera flotation, bikagabanya hydrophilique na buoyancy, bityo bikabuza ayo mabuye y'agaciro kureremba hamwe namabuye ya zahabu.Inzitizi z'umuringa wa sulfate zongerwaho kenshi kugirango zibike amabuye y'agaciro adakenera flotation hepfo.

4. Ikoreshwa nka minisiteri yubutaka

Hindura imiterere yumubiri nu mubiri wubutaka.Mu gucukura amabuye ya zahabu, ibintu byamashanyarazi hamwe na hydrophilique yubutaka bwa minerval nibintu byingenzi bihindagurika.Sulfate y'umuringa irashobora gukora ion ya oxyde y'umuringa mu myunyu ngugu, igakora hamwe na ion z'icyuma hejuru y’ubutare, kandi igahindura imiterere y’imiti.Sulfate y'umuringa irashobora kandi guhindura hydrophilique yubutaka bwamabuye y'agaciro kandi ikongerera aho uhurira hagati yamabuye y’amazi n’amazi, bityo bigatuma ingaruka za flotation ziva mu birombe bya zahabu.
