Izinyathelo zokuqapha zokusetshenziswa nokugcinwa kwe-xanthate

[incazelo evamile]I-Xanthate iyi-flotation sulfide mineral, efana ne-galena, i-sphalerite, i-actinide, i-pyrite, i-mercury, i-malachite, isiliva yemvelo kanye negolide lemvelo, Ingumqoqi osetshenziswa kakhulu.

Enqubweni ye-flotation kanye ne-beneficiation, ukuze kuhlukaniswe ngokuphumelelayo amaminerali awusizo kumaminerali e-ganggue, noma ukuhlukanisa amaminerali ahlukahlukene awusizo, ngokuvamile kuyadingeka ukwengeza ama-reagents ukuze kuguqulwe izakhiwo ezingokwenyama namakhemikhali zendawo yamaminerali kanye nezakhiwo ze-medium. .Lawa ma-reagents ngokuhlangene abizwa ngokuthi ama-flotation reagents.I-Xanthate ingumqoqi osetshenziswa kakhulu ukuntanta kwe-sulfide ores.

I-Xanthate ihlukaniswe nge-ethyl xanthate, i-amyl xanthate nokunye.I-Xanthate enama-athomu e-carbon angaphansi kwezi-4 eqenjini le-hydrocarbon, iqoqo elibizwa ngokuthi i-xanthate yezinga eliphansi, i-Xanthate enama-athomu e-carbon angaphezu kuka-4 ngokuhlangene kubizwa ngokuthi i-xanthate ethuthukisiwe. ukuze wenze i-xanthate isebenzise ukusebenza kahle kwayo ngokugcwele, Kufanele kuqashelwe lezi zici ezilandelayo lapho usebenzisa futhi ugcinwa:

1. Yisebenzise ku-alkaline pulp ngangokunokwenzeka.Ngenxa yokuthi i-xanthate kulula ukuhlukana emanzini, izovela i-hydrolysis kanye nokubola.Uma izimo ezithile zidinga ukuthi isetshenziswe ku-acid pulp, i-xanthate ethuthukisiwe kufanele isetshenziswe.Ngoba i-xanthate ethuthukisiwe ihlakazeka kakhulu. kancane kune-xanthate yezinga eliphansi ku-acid pulp.

2. Isixazululo se-xanthate kufanele sisetshenziswe njengoba kudingekile, ungaxubanisi kakhulu ngesikhathi esisodwa, futhi ungaxubi namanzi ashisayo.Endaweni yokukhiqiza, i-xanthate ivame ukwakhiwa ibe yisisombululo se-aqueous esingu-1% ukuze sisetshenziswe.Ngoba i-xanthate kulula ukwenza i-hydrolyze, ukubola nokwehluleka, Ngakho-ke ungahambelani kakhulu ngesikhathi.Ayikwazi ukulungiswa ngamanzi ashisayo, ngoba i-xanthate izobola ngokushesha uma kushisa.

3. Ukuze uvimbele i-xanthate ekuboleni nasekuhlulekeni, kufanele igcinwe endaweni evaliwe, Vimbela ukuthintana nomoya omanzi namanzi, Gcina endaweni epholile, eyomile futhi enomoya omuhle, Ungashisi, unake ukuvimbela umlilo.
