Izilumkiso zokusetyenziswa kunye nokugcinwa kwe-xanthate

[inkcazo jikelele]I-Xanthate yi-flotation sulfide mineral, efana ne-galena, i-sphalerite, i-actinide, i-pyrite, i-mercury, i-malachite, isilivere yendalo kunye negolide yendalo, Yeyona nto isetyenziswa kakhulu ngumqokeleli.

Kwinkqubo ye-flotation kunye ne-beneficiation, ukwenzela ukwahlula ngokufanelekileyo iiminerali eziluncedo kwiminerali ye-ganggue, okanye ukwahlula iiminerali ezahlukeneyo eziluncedo, kuhlala kuyimfuneko ukongeza ezinye ii-reagents zokutshintsha iipropathi ezibonakalayo kunye neekhemikhali zomgangatho weminerali kunye neempawu ze-medium. .Ezi reagents ngokudibeneyo zibizwa ngokuba zii-flotation reagents.I-Xanthate yeyona nto isetyenziswa ngokuqhelekileyo ekuqokeleleni i-flotation ye-sulfide ores.

I-Xanthate ihlulwe kwi-ethyl xanthate, i-amyl xanthate kunye nokunye.I-Xanthate engaphantsi kwe-4 ye-athomu ye-carbon kwiqela le-hydrocarbon, ngokudibeneyo ebizwa ngokuba yi-low-grade xanthate, i-Xanthate ene-athomu ye-carbon engaphezu kwe-4 ngokudibeneyo ibizwa ngokuba yi-xanthate ephezulu. ukuze wenze i-xanthate isebenzise ngokupheleleyo ukusebenza kwayo, Ingqalelo kufuneka ihlawulwe kule miba ilandelayo xa usebenzisa kwaye uyigcina:

1. Yisebenzise kwi-alkaline pulp kangangoko kunokwenzeka.Ngenxa yokuba i-xanthate ilula ukuchithwa emanzini, iya kuvela i-hydrolysis kunye nokubola.Ukuba ezinye iimeko zifuna ukuba zisetyenziswe kwi-acid pulp, i-xanthate ephezulu kufuneka isetyenziswe.Ngenxa yokuba i-xanthate ephezulu idibanisa ngakumbi. kancinane kune-xanthate yomgangatho ophantsi kwi-asidi pulp.

2. Isisombululo se-xanthate kufuneka sisetyenziswe njengoko sifunekayo, musa ukuxubana kakhulu ngexesha elinye, kwaye ungaxubeki ngamanzi ashushu.Kwindawo yokuvelisa, i-xanthate ngokuqhelekileyo iqulunqwe kwi-1% yesisombululo samanzi sokusetyenziswa.Ngenxa yokuba i-xanthate kulula ukwenza i-hydrolyze, ukubola kunye nokusilela, ke sukuthelekisa kakhulu ngexesha.Ayinakulungiswa ngamanzi ashushu, kuba i-xanthate iya kubola ngokukhawuleza kwimeko yokushisa.

3. Ukuze uthintele i-xanthate ukubola kunye nokungaphumeleli, kufuneka igcinwe kwindawo evaliweyo, Ukuthintela ukudibanisa nomoya omanzi kunye namanzi, Gcina kwindawo epholileyo, eyomileyo kunye neyomoya, Musa ukufudumala, ubeke ingqalelo ekuthinteleni umlilo.
