[tsananguro huru]Xanthate ndeye flotation sulfide mineral, yakadai se galena, sphalerite, actinide, pyrite, mercury, malachite, sirivha chaiyo uye goridhe rechisikigo, Ndiyo inonyanya kushandiswa muunganidzi.
Mukuita flotation uye beneficiation, kuitira kunyatsoparadzanisa anobatsira zvicherwa kubva gangue zvicherwa, kana kupatsanura akasiyana siyana anobatsira zvicherwa, zvinowanzodiwa kuwedzera mamwe mareagents kushandura iyo yemuviri uye kemikari zvimiro zveiyo mineral surface uye zvimiro zvepakati. .Aya ma reagents akaungana anonzi flotation reagents.Xanthate ndiyo inonyanya kushandiswa muunganidzi we flotation ye sulfide ores.
Xanthate yakakamurwa kuita ethyl xanthate, amyl xanthate zvichingodaro.Xanthate ine isingasviki 4 carbon atomu muboka re hydrocarbon, pamwe chete inonzi yakaderera-giredhi xanthate, Xanthate ine anopfuura 4 carbon maatomu ari pamwe chete anonzi advanced xanthate.In kuti uite xanthate ichiita zvizere kushanda kwayo, Kuchenjerera kunofanirwa kubhadharwa kune zvinotevera zvinhu paunenge uchishandisa nekuchengetedza:
1. Ishandise mu alkaline pulp sezvinobvira.Nekuti xanthate iri nyore kuparadzanisa mumvura, ichamuka hydrolysis uye kuora.Kana mamwe mamiriro ezvinhu achida kuti ashandiswe mu acid pulp, xanthate yepamusoro inofanira kushandiswa.Nekuti xanthate yakanyanyisa inoparadzana zvakanyanya. zvishoma nezvishoma pane yakaderera-giredhi xanthate mune acid pulp.
2. Mushonga we xanthate unofanirwa kushandiswa sezvinodiwa, usasanganise zvakanyanya panguva imwe chete, uye usasanganise nemvura inopisa.Panzvimbo yekugadzira, xanthate inowanzogadzirwa mu 1% aqueous solution yekushandiswa.Nekuti xanthate is nyore kuita hydrolyze, kuora uye kutadza, Saka usaenderane zvakanyanya panguva.Haikwanisi kugadzirirwa nemvura inopisa, nokuti xanthate ichaora nokukurumidza kana inopisa.
3. Kuti udzivise xanthate kubva pakuora uye kukundikana, inofanira kuchengetwa munzvimbo yakavharwa, Kudzivirira kusangana nemhepo yakanyorova nemvura, Chengetedza munzvimbo inotonhorera, yakaoma uye yakanyatsoputika, Usapisa, teerera kudzivirira moto.
