Chidule cha Chitsogozo ndi Zizindikiro Za Minecral

1. Zotsogolera ndi zinc flootation

Osonkhanitsa omwe amagwiritsidwa ntchito kwambiri kwa otsogola-zinc amaphatikiza:

1. Xanthate. Mtundu wa nthumwi umaphatikizapo xanthate ester, xinthate ester, etc.

2. Nitrogen nayitrogeni, monga ethyl sulfure nayitrogeni, ali ndi mphamvu zowongolera kuposa xanthate. Imakhala ndi luso lopereka la Galena ndi Chalcopyyrrite, koma kulephera kutolera zolemba zabwino, kuthamanga mwachangu, komanso kugwiritsa ntchito ochepa kuposa xanthate. Ili ndi chiwerengero cholimba cha malo osungirako zamiyala ya sulfa. Ikagwiritsidwa ntchito posankha ma ores-ad-sulfure, imatha kupeza zovuta zina kuposa xanthate.

3.black mankhwala

Ufa wakuda ndi wotolera wa sulfide ores, ndipo luso lake lotolera limakhala lofooka kuposa la xanthate. Katundu wa dithiculocarbyl dithiososphate wa ion yomweyo ion ndi yayikulu kuposa ya xanthate ya ion. Mankhwala akuda ali ndi malo omenyera.

Zofananira ndi ufa wakuda m'mafakitale zimaphatikizapo: No. 25 ufa wakuda, koma ufa wakuda, amine wakuda ufa, ndi ufa wakuda. Pakati pawo, atylamomoni akuda (Dibutyl Amonium Dithiososphate) ndi ufa woyera, umatembenuka wakuda pambuyo pofufuza, ndipo ali ndi malo ena owonda. Ndioyenera kubwereka kwa sulfation ya ma ores monga mkuwa, kutsogolera, zinc, ndi nickel. . Pofooka alkaline slurry, kuthekera kwa PRYRITE ndi PRYHthot ndi ofooka, koma kuthekera kwa Galena ndi wamphamvu.

2. Kutsogolera ndi zinc flootation Wothandizira

Malinga ndi gawo lawo pakuchita bwino, adjusts amatha kugawidwa: zoletsa, oyendetsa mafa, osamwa kwambiri, ophatikizika ndikupanganso kukonzanso.

Maulendo akuphatikizira mitundu ingapo yopangira (monga mchere, zokumba ndi asidi) ndi zopangira zachilengedwe. Wothandizira yemweyo nthawi zambiri amasewera maudindo osiyanasiyana mosiyanasiyana.

Zoletsa:

1. Laimu laimu (CAO) imakhala ndi madzi othamanga komanso madzi ndi madzi kuti apange Liimu ya hydratigh a ca (o) 2. Ndikosavuta kusungunuka m'madzi ndipo ndi alkali wamphamvu. Zomwe zimawonjezera pamene kuwonjezeredwa ku Flotation Slotry ndi motere:

CAO + h2o = ca (o) 2

Ca (oh) 2 = caoh ++-

Caoh + = Ca2 ++ 0H-

Lime nthawi zambiri imagwiritsidwa ntchito kuwonjezera mtengo wa slurry ndikuletsa mchere wa sulfisi. Mkuwa sulfide, mtovu, ndi zinc, nthawi zambiri amapita limodzi ndi rofide wa sulfide wa salfide wa ma ures (alyrite, a Marrnorsnite (monga arropnite)). Kuti muwongolere bwino mkuwa, kutsogolera, ndi mineral, laimu nthawi zambiri imawonjezeredwa kuti ilepheretse mchere wa sulfisi.

2. Cyanside (Nacn, KCN)

Cyanside ndi chovomerezeka choletsa pakutsogolera ndi kusanja. CYanide amakhala makamaka sodium cyanja ndi potaziyamu cyanjalide, ndipo calcium cyanside amagwiritsidwanso ntchito.

Cyanjade ndi mchere wopangidwa ndi maziko olimba komanso ofooka acid. Amakhala ndi ma hydrolyzied mu slurry kuti mupange HCN ndi CN-

KCN = K ++ CN-

Cn + h2o = hcn ++

Itha kuwoneka kuchokera kuzofanana pamwambapa zomwe mu alkalinine slorry, kuchuluka kwa mapende, omwe ndi opindulitsa. Ngati PH imatsitsidwa, hcn (hydrocyonic acid) imapangidwa ndipo zotsatira za choletsa zimachepetsedwa. Chifukwa chake, mukamagwiritsa ntchito cyanide, mtundu wa kusalala uyenera kusungidwa.

3.Zinc sulfate

Chopangidwa ndi choyera cha zinc sulfate ndi choyera choyera, kusungunuka mosavuta m'madzi, ndipo ndi choletsa cha stabilerate. Nthawi zambiri zimakhala ndi mphamvu zokha mu alkaline slorry. Zowonjezera Ph wa slurry, zowonekeratu zowonjezera. Zirc sulfate imatulutsa zotsatirazi m'madzi:

ZNO4 = ZN2 ++

Zn2 ++ 2H220 = ZN) 2 + 2H +

ZN (O) 2 ndi mafuta ophatikizika omwe amasungunuka mu acid kuti apange mchere.

ZN (O) 2 + H2S04 = ZNSO4 + 2H2O

Mu alkaline sing'anga, Hzno2- ndi Zno22 - amapezeka. Adsorption yawo ku michere imawonjezera hydrophilicity ya michere ya mchere.

Zn (O) 2 + Naoh = nahzno2 + h2o

Zn (O) 2 + 2naoh = Na2zno2 + 2H2o

Pamene zinc sulfate imagwiritsidwa ntchito yokha, zotsatira za choletsa sizabwino. Nthawi zambiri zimagwiritsidwa ntchito limodzi ndi cyanide, sodium sulfide, sulfite kapena thisulfate, sodium carbonate, etc.

Kugwiritsa ntchito kosakanikirana kwa zinc sulfate ndi cyanside kumatha kukulitsa zotsatira za stabileite. Chigawo chomwe chimagwiritsidwa ntchito ndi: cyanside: zinc sulfate = 1: 2-5. Pakadali pano, CN- ndi ZN2 + yankhani colloidal zn (CN) 2.
