Kudyidzana kweSodium Sulfide nemamwe maReagents muFlotation process

Mubasa rekugadzirisa zvicherwa , kuyerera kwemvura (flotation) inzira inoshandiswa zvakanyanya pakuparadzanisa zvicherwa zvinokosha kubva kugangue. Sodium sulfide inoita basa guru mukuita uku, ichinyanya kushandiswa kugadzirisa pH ye pulp, sulfidize, depress, uye kubvisa pamusoro pezvicherwa. Kudyidzana kwayo neCollectors , Frothers , uye Regulators kwakaoma uye kunokanganisa zvakanyanya kushanda uye kusarudzwa kwekufamba kwemvura (flotation).

Kupesvedzera paSulfide Mineral Collectors

Kune vanounganidza zvicherwa zvesulfide zvakaita sexanthates nedithiophosphates, kana chiyero cheSodium sulfide chakakodzera, chinogona kuwedzera hydrophobicity yenzvimbo ine sulfide, zvichiita kuti vanounganidza vakwanise kunyudza zviri nani pamusoro penzvimbo ine mineral uye kuvandudza kunyorova kwezvicherwa. Zvisinei, kana sodium sulfide yakawandisa, inoumba firimu rinonyudza pamusoro penzvimbo ine sulfide, zvichitadzisa kunyudzwa kwevanobatanidza uye nokudaro zvichiita basa rekudzivirira. Semuenzaniso, mukunyorova kwemhangura-sulfur ore, huwandu hwakakodzera hwesodium sulfide hunogona kukurudzira kuunganidzwa kwechalcopyrite nexanthate, nepo huwandu hwakawanda huchidzivirira kunyorova 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 Carbon ate kuti igadzirise pH ye pulp pamwe chete. Semuenzaniso, mukuyerera kwe lead-zinc ore, sodium sulfide ne lime zvinowanzo shandiswa pamwe chete kuchengetedza pulp alkaline, kudzivirira kusvibiswa kwemaminerari akadai se pyrite, uye kuvandudza kusarudzwa kwe flotation kwe lead-zinc ore.

Kudyidzana neDepressants

Sodium sulfide ine mhedzisiro yakafanana yekudzivirira kune zvimwe zvinoderedza kuora mwoyo zvakaita secyanide negirazi remvura. Mune zvimwe zviitiko, zvinogona kushandiswa pamwe chete kuti zviwedzere mhedzisiro yekudzivirira. Semuenzaniso, mukuyerera kwecopper-lead-zinc polymetallic ore, kushandiswa pamwe chete kwesodium sulfide necyanide kunogona kusimbisa kudziviswa kwesphalerite nepyrite, zvichiita kuti copper-lead iparadzwe zvakanaka kubva ku zinc-sulfur. Zvisinei, kutarisirwa kunofanira kupihwa pakudzora dosage uye kuwedzera kwehuwandu; zvikasadaro, kudziviswa kwakanyanya kunogona kuitika, zvichikanganisa mwero wekupora.

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.
