Iyo inowanzoshandiswa kurongedza nheyo maitiro ekugadzirisa maronda-zinc sulfide eres sulfide eres kusanganisa kuronga kwekutanga, yakasanganiswa blotation uye kuronga kwakaenzana.
Hazvina mhosva kuti ndeipi maitiro anoshandiswa, iwe unosangana nematambudziko ekutungamira-zinc kuparadzaniswa uye zinc-sulfur yekuparadzaniswa. Iyo kiyi yekuparadzanisa ndeye kusarudzwa zvine musoro uye kwakaderera kwevaridzi.
Sezvo kukwezva kwevakawanda galena kuri nani pane iyo yeSphelerite, nzira dzese dzekudzvinyirira zinc uye kutungamira kuyerera kunowanzoshandiswa. Mishonga yemishonga yekuvhiringidza zinc inosanganisira cyanide nzira uye Cyanide-yemahara nzira. MuCyanide nzira, zinc sulfate inowanzoshandiswa mukubatanidzwa neCyanide yekuwedzera iyo inhibitory. Semuenzaniso, imwe nzira yekugadzirisa inoshandisa sodium cyanide uye zinc sulfate musanganiswa kuti uderedze iyo cyanide dosage kusvika pamakumi maviri ~ 30G / uye vamwe vanotozvitora kusvika 3 ~ 5G / t. Dzidzira zvakaratidza kuti hachiwedzeredze iyo dosage, asi zvakare inowedzera huwandu hwekudzora.
Kuti udzivise kurasa cyanide kusvibiswa kune zvakatipoteredza, maCyanide-emahara-emahara kana nzira dzedhingi dziri kusimudzirwa pari pamba uye kunze kwenyika. Iyi inotevera nzira dzekutamba-dzisina kujairika dzinowanzoshandiswa mumutungamiri uye neZinc kupatsanura indasitiri:
1. Floating kutungamira inhibits zinc
(1) zinc sulfate + sodium carbonate (kana sodium sulfide kana lime);
Imwe inotungamira-zinc-sulfur yangu inogamuchira prefertial flotation maitiro. ZNSO4 + NA2C3 (1.4: 1) yaishandiswa kudzvinyirira Spalerite kana kuyerera. Kana tichienzanisa neyekutungamira nzira, giredhi rekutungamira rakawedzera kubva ku39.80%, uye chiyero chekupora chakasvika kubva kuZinc Rate yekudzoreredza yakawedzera kubva 88.54% kusvika 90.03%.
(2) zinc sulfate + Surifiti;
(3) zinc sulfate + siosulfate;
(4) Sodium hydroxide (pH = 9.5, inounganidzwa ne dema poda);
(5) Shandisa zinc sulfate ega kuti inhibit zinc;
(6) Shandisa So2 gasi kuti udzvinyirire zinc.
2. Flatating zinc kudzvinyirira kutungamira
(1) lime;
(2) girazi remvura;
(3) girazi remvura + sodium sulfide.
Nzira dziri pamusoro apa dzinoshandiswa apo Galena rikanyanyisa oxidized uye kuwanda kwayo kunova murombo.
Zvekutungamira kwekuyerera, mushonga mutema uye Xanthathe zvinowanzoshandiswa sevatambi, kana maEthyl Sulfide ega neKusarudza kwakanaka kunoshandiswa semuteresi. Zvimwe zvekuzvimiririra zvirimwa zvakare zvinosanganisa sulfosucccinic acid (a-22) ne xanthate.
Sezvo lime ine inhibitory mhedzisiro paGalena, kana paine plrite iri mu ore, inonyanya kubatsira kushandisa sodium carbonate sePH adjuster kutungamira. Kana iyo pyrite zvirimo mune iyo mbichana ore yakakwira, zviri nani kushandisa lime kunge ph adjuster. Nekuti lime inogona kudzivirira iyo pyrite yakabatana, inobatsira kuyerera.
Kumutsa kwakadzvanywa kwakadzvanywa sphalerite uchishandisa mhangura sulfate. Kuti udzivise mhangura sulfate uye xanthate zvakananga kuumba marara exanthate panguva yekusanganisa kwemumiririri
Kana paine zvikamu zviviri zviri nyore kuyerera uye izvo zvakaoma kuyerera muSphalerite, kuitira kuti uwedzere nzvimbo yetungamira uye zinc, maitiro akaomarara anogona kutorwa, ayo anonyanya kushandisa kutungamira uye kuyambutsa kutungamira uye zinc.
3.Method yeZinc uye Sulf Kuparadzanisa
(1) kuyerera zinc kudzvinyirira Sulfur
1. Lime lime
Izvi ndizvo zvinonyanya kushandiswa sulfu kudzvinyirira nzira. Iyi nzira inogona kushandiswa kugadzirisa rat ore uye inoparadzanisa zinc-sarufa yakasanganiswa. Paunenge uchishandisa nzira iyi, shandisa lime kugadzirisa iyo pH, kazhinji pamusoro pa 11, zvekuti puroite inonatswa. Iyi nzira iri nyore, uye yemakemikari inoshandiswa ndeye lime, iyo yakachipa uye nyore kuwana. Nekudaro, kushandiswa kwe lime kunogona kukonzera kupenya kwemidziyo yekurima, kunyanya pombi, uye sulfu inotarisa zvisiri nyore kune faira, zvichikonzera kuti unyoro hwepamusoro hwekutarisa.
2.Heating nzira
Kune mamwe maPyrites ane yakanyanya plishktonic chiitiko, kudzvinyirirwa neLime nzira kazhinji haiwanzo kushaya basa. Kana iyo slurry ichipiswa, iyo yemukati oxidation madhigirii eSphalerite uye pyrite akasiyana. Mushure mekunge zinc-sarufa yakavhenganiswa inotsemurwa, yakashambadzirwa uye yakakurudzirwa, iyo yekukwira kwePyrite inoderera, nepo kuyerera kweSphalerite kuchiramba.
Tsvagurudzo inoratidza kuti zinc uye sarufa inogona kupatsanurwa nekudziya kupisa kwekuparadzaniswa kweZinc-sarufa yakasanganiswa. Kupatsanurwa kwekupatsanurwa kweshiri makumi mana neshanu c, uye kupatsanurwa kwakanaka pasina kupisa kana kuwedzera chero makemikari anogona kuparadzanisa zinc nesarufa. Iyo indekisi yakawanikwa ndeye 6.2% yakakwirira kupfuura zinc inotarisa yakagadzirwa neye lime nzira, uye chiyero chekupora chiri 4.8% kumusoro.
3. Lime kuwedzera zvishoma huwandu hwe cyanide
Kana Lime yega isingakwanisi kudzora svutugadzike shuwa, wedzera huwandu hwechirume (semuenzaniso: NACN5G
(2) kuyerera Sulfur Suppresses Zinc
Sulfur Dioxide + Steam Heating Nzira iyi nzira yakaiswa muBrunswick Mineral yekugadzirisa chirimwa muCanada. Iyo zinc inotarisa yakawanikwa neiyo chirimwa ine yakawanda yePyrite. Kuti uvandudze mhando, iyo slurry inobatwa ne sarufa dioxide gasi uye ikapomerwa neSteam kuti udzivise zinc uye float sulfu.
Iyo nzira chaiyo ndeyekuburitsa Sulfur diexide gasi kubva kuzasi kweiyo yekutanga tangi uye kudzora iyo pH = 4.5 kusvika 4.8. Jekiseni inopinda mune yechipiri uye yechitatu inosimudzira matangi uye kupisa iyo kusvika pamakumi manomwe kusvika ku82 kusvika ku82 Paunenge uchicheka pyrite, iyo pH iri 5.0 ~ 5.3, uye Xanthate inoshandiswa seMukuru. Iyo flotation mireya ndiyo yekupedzisira zinc inotarisa. Kuwedzera kune pyrite, chigadzirwa chefomwe chinewo zinc. Mushure mekusarudzwa, inoshandiswa sepakati ore uye yakadzokera kune yepakati ore pamberi pechiitiko chekudzikisira. Kutonga kwakaringana kwePH uye tembiricha ndiyo kiyi yeichi maitiro. Mushure mekurapwa, chigadzirwa cheZinc chakatarisa chakawedzera kubva pa50% kusvika ku51% zinc kusvika ku57% kusvika ku58%.
