Kudyidzana kweSodium Sulfide nemamwe maReagents muFlotation process

Mumunda we Mineral processing, flotation inzira inoshandiswa zvakanyanya yekuparadzanisa zvicherwa zvakakosha kubva kune gangue. Sodium sulfide inobata basa rakakosha mukuita uku, kunyanya kushandiswa kugadzirisa pH kukosha kwepulp, sulfidize, depress, uye kubvisa pamusoro pezvicherwa. Kudyidzana kwayo ne Vanounganidza, Madzibaba, uye Regulators zvakaoma uye zvakanyanya kukanganisa kushanda uye kusarudza kwe flotation.

Kudyidzana nevaunganidzi

Kupesvedzera paSulfide Mineral Collectors

Kune vaunganidzi vakajairika vezvicherwa zve sulfide senge xanthates uye dithiophosphates, kana dosi ye Sodium sulfide yakakodzera, inogona kukwidziridza hydrophobicity ye sulfide mineral surface, zvichiita kuti vateresi vashambadzire zviri nani pane mineral surface nekuvandudza kutenderera kwemaminerari. Nekudaro, kana sodium sulfide yakawandisa, inoumba hydrophilic firimu pamusoro pemaminerari e sulfide, ichitadzisa kushambadza kwevanotora uye nekudaro kutamba inhibitory basa. Semuenzaniso, mukutenderera kwemhangura-sarufa ore, yakaringana yesodium sulfide inogona kukurudzira kuunganidzwa kwechalcopyrite ne xanthate, nepo kuwanda kwakawanda kunotadzisa kutenderera kwechalcopyrite.

Kufurira paOxide Mineral Collectors

Mukutenderera kwemaminerari eoxide, sodium sulfide inogona sulfidize pamusoro peiyo oxide minerals, ichibvumira kuti iunganidzwe ne sulfide mineral collectors. Semuyenzaniso, kana uchishandisa mafuta asidhi vaunganidzi kuti kuyangarara cerussite, sodium sulfide kutanga sulfidize pamusoro cerussite uye ipapo anopindirana ane fatty asidhi muunganidzi, kunatsiridza flotation kuitika cerussite.

Kudyidzana neFrothers

Sodium sulfide pachayo haina furo pfuma, asi inogona kukanganisa zvimiro zvepulp uye nepamusoro pemamiriro emaminerari, nekudaro ichipesvedzera kupupuma kwefuro. Huwandu hwakakodzera hwesodium sulfide hunoita kuti iyo hydrophobicity yemaminerari ikwane, iyo inokodzera kusungirirwa kwemabhubhu kune zvicherwa, kuvandudza iyo aeration mhedzisiro uye furo kugadzikana kwemafrothers. Nekudaro, yakawandisa yesodium sulfide inoparadzira iyo yakanaka slime mu pulp, kuwedzera pulp viscosity, kuita kuti furo rinamate, uye kukanganisa kugadzikana uye kuyerera kwefuro, izvo zvisingakodzeri kukwenya kwefuro rekuyerera uye kupatsanurwa kweiyo concentrate.

Kudyidzana nevamwe Regulators

Synergistic Mhedzisiro ine pH Regulators

Sodium sulfide inonyungudika kuita alkaline uye inogona kushanda pamwe chete nedzimwe pH regulators dzakadai se lime ne sodium kabhoniKugadzirisa pH ye pulp pamwe chete. Semuenzaniso, mukuyerera kwe lead-zinc ore, sodium sulfide ne lime zvinowanzo shandiswa pamwe chete kuchengetedza pulp iri mu alkaline, kudzivirira kusvibiswa kwemaminerari akadai se pyrite, uye kuvandudza kusarudzwa kwe lead-zinc ore mu flotation.

Kudyidzana neDepressants

Sodium sulfide ine yakafanana inhibitory mhedzisiro kune mamwe anodzvinyirira akadai cyanide uye girazi remvura. Mune zvimwe zviitiko, vanogona kushandiswa pamwe chete kuwedzera inhibitory effect. Semuenzaniso, mukutenderera kwemhangura-lead-zinc polymetallic ore, kushandiswa kwakasanganiswa kwe sodium sulfide uye cyanide kunogona kusimbisa inhibition ye sphalerite uye pyrite, kuwana kuparadzaniswa kunobudirira kwemhangura-lead kubva zinc-sarufa. Nekudaro, kutarisisa kunofanirwa kubhadharwa pakudzora dosi uye kuwedzera kutevedzana; kana zvisina kudaro, inhibition yakawandisa inogona kuitika, inokanganisa chiyero chekudzorera.

Kudyidzana neActivators

Sodium sulfide ine activation mhedzisiro pane mamwe mamineral akavharirwa uye inogona kushandiswa pamwe chete nema activators. Semuenzaniso, mukupatsanurwa kwe flotation ye sulfide copper-lead ore, galena inhibited by cyanide inogona kushandiswa ne sodium sulfide uye zvino inounganidzwa ne ethyl thionocarbamate kuti iwane kuparadzaniswa kwemhangura uye mutungamiri. Panguva imwecheteyo, sodium sulfide inogonawo kukanganisa mhedzisiro yemamwe activator. Semuenzaniso, yakawandisa yesodium sulfide inogona kupedza iyo inoshanda ion mu pulp, ichideredza activation mhedzisiro yeanoshanda.

Mukupedzisa, kunzwisisa kupindirana kwesodium sulfide nemamwe mareagents muhurongwa hwekuyerera kwakakosha zvikuru pakugadzirisa flotation process, kuvandudza mwero wekudzoreredza uye giredhi remaminerari akakosha, uye kuderedza mutengo wekugadzirisa zvicherwa. Mainjiniya ekugadzira zvicherwa anofanirwa kunyatso gadzirisa dosage uye kuwedzera kutevedzana kweakasiyana reagents zvinoenderana nechaiyo zvimiro zveore kuti uwane yakanakisa flotation mhedzisiro.
