Iindima kunye nezicelo zeSodium Cyanide Solution

Sodium i-cyanide isisombululo, kunye nefomula yeekhemikhali i-NaCN kwindawo enamanzi, yinto ebaluleke kakhulu kwimizi-mveliso kunye nekhemikhali, nangona ityhefu kakhulu. Eli nqaku lingena kwiindima ezahlukeneyo kunye nokusetyenziswa kwe Isodium cyanide isisombululo.

1. Igolide kunye neNgxowa yeNsimbi exabisekileyo kwiMigodi

1.1 Ingcaciso ngeNkqubo

Enye yezona zicelo ezaziwa kakhulu ze isisombululo se-sodium cyanide ikwishishini lemigodi, ingakumbi ukumba igolide nezinye iintsimbi ezixabisekileyo. Nini Isodium cyanide isisombululo sixutywe negolide - i-ores ethwele, igolide kwi-ore isabela kunye ne-cyanide ions phambi kwe-oksijini evela emoyeni nasemanzini. Le mpendulo yenza igolide enyibilikayo - icyanide complex. Nje ukuba igolide ikule fomu enyibilikayo, inokwahlulwa kwizinto eziseleyo ze-ore.

1.2 Iindlela zokutsalwa

Kukho iindlela ezimbini eziqhelekileyo ezisetyenziswayo kule nkqubo yokukhutshwa:

• UkuLeaching kweTanki: Intsimbi yegolide ifakwe kwiitanki ezinkulu kwaye ixutywe kunye sodium cyanide isisombululo. Emva kwexesha elithile, xa igolide inyibilika kwisisombululo, isisombululo se-cyanide esisetyenzisiweyo kunye ne-ore eseleyo idluliselwa kwiindawo zokugcina ii-tailings.

• Haap Leaching: Igolide ekrwada ekrwada ifunjwa ibe ziimfumba, kwaye umxube wesodium cyanide ugalelwa phezu kwemfumba. Njengoko isisombululo sigqobhoza kwintsimbi ekrwada, sinyibilikisa igolide. Isisombululo esiqulathe igolide enyityilisiweyo siqokelelana ezantsi kwemfumba ze emva koko siqokelelwe ukuze kuqhutyekwe nokulungiswa kwakhona igolide.

2. Ukuchongwa kombane

2.1 Umsebenzi kwiiBhafu zoMbane

Isisombululo sesodium cyanide sisetyenziswa kwiibhafu ze-electroplating kwiintsimbi ezifana nobhedu, isilivere, i-cadmium, kunye ne-zinc. Kwi-electroplating, injongo kukubeka umaleko omncinci wentsimbi efunwayo kwi-substrate. I-Cyanide ion kwisisombululo se-sodium cyanide idlala indima ebalulekileyo. Banciphisa i-anode polarization, ukuqinisekisa ukuba i-anode, umthombo wesinyithi oza kuhlanjululwa, inyibilika ngokulinganayo, okubalulekileyo ekuboneleleni okuhambelanayo kwee-ion zetsimbi kwisisombululo se-plating. Ukongezelela, ubukho bee-ion ze-cyanide kunceda ekuzinziseni isisombululo se-electroplating, ukuthintela imvula yeekhompawundi zetsimbi ezinokuphazamisa inkqubo yokucwenga. Zikwaphucula i-cathode polarization, ekhokelela ekubekweni okufanayo ngakumbi kwesinyithi kwi-cathode, i-substrate iyacakwa, ikhokelela kwityabeka yesinyithi egudileyo kwaye ibambelela ngakumbi.

3. Ukwenziwa kweekhemikhali

3.1 Ukuveliswa kwee-Inorganic Cyanides

Isisombululo se-sodium cyanide sisixhobo esiphambili sokuqalisa ukuveliswa kweentlobo ezahlukeneyo ze-inorganic iicyanides. Ngokomzekelo, enye i-cyanide ye-inorganic eveliswa kuyo isetyenziswa kwishishini lokutya njenge-anticaking agent kunye nokuveliswa kwemibala eluhlaza. Enye, xa ifunyenwe ngokusabela ngeetyuwa ezithile, isetyenziswa kwizicelo ezifanayo njenge-sodium cyanide, njengakwizinto ezithile. ukutsalwa kwegolide iinkqubo kunye nezinye organic syntheses.

3.2 Ukudityaniswa kweeNdibaniselwano zezinto eziphilayo

Kwimichiza yezinto eziphilayo, isisombululo se-sodium cyanide sisetyenziselwa ukwazisa iqela le-cyano kwiimolekyuli zezinto eziphilayo, okuyinyathelo elibalulekileyo ekuhlanganiseni izinto ezininzi eziphilayo. Xa i-alkyl halide isabela ngesisombululo se-sodium cyanide, i-compound yenziwa. Le khompawundi inokuphinda iguqulwe ibe ngamanye amaqela asebenzayo afana ne-carboxylic acid kunye ne-amines ngokusabela kwamachiza okulandela, okwenza isisombululo se-sodium cyanide sibe yi-reagent exabisekileyo ekudityanisweni kwamayeza, ii-agrochemicals, kunye nezinto ezahlukeneyo eziphilayo.

4. Ukucocwa kwesinyithi kunye noNyango loMphezulu

4.1 Ukunyibilikisa ii-Oxides zeMetal kunye noBumdaka

Isisombululo se-sodium cyanide singasetyenziselwa ukucoca isinyithi. Ezinye iioksidi zetsimbi kunye nokungcola kumphezulu wesinyithi kunokusabela kunye neeoni ze-cyanide. Ngokomzekelo, i-oxide yobhedu phezu kobhedu inokusabela ngesisombululo se-sodium cyanide phantsi kweemeko ezithile. Iiyoni ze-cyanide zenza ii-complexes kunye nee-ion zetsimbi ezivela kwi-oxides, zisuse ngokufanelekileyo i-oxide layer kwaye zishiye isinyithi esicocekileyo. Oku kuluncedo ekulungiseleleni imiphezulu yentsimbi ukuqhubekeka phambili njengokupeyinta, i-soldering, okanye i-electroplating.

5. ULawulo lweZitshabalalisi (Lunomlinganiselo kwaye luLawulwe kakhulu)

5.1 Sebenzisa njenge-Rodennticide

Ngaphambili, isisombululo se-sodium cyanide sisetyenziswe njenge-rodenticide. Ubume bayo obuyityhefu kakhulu buyenza ibulale iimpuku. Nangona kunjalo, ngenxa yetyhefu egqithisileyo kungekuphela nje kwizitshabalalisi ekujoliswe kuzo kodwa nakwizinto ezingajoliswanga, kuqukwa nabantu, ukusetyenziswa kwayo njengeyeza lokubulala iinkuni kuthintelwe kakhulu kumazwe amaninzi. Umngcipheko wokuvezwa ngengozi kunye nokubanakho ukungcoliseka kwendalo yinkxalabo enkulu ehambelana nokusetyenziswa kwayo kulawulo lwezinambuzane.

Iingqwalaselo zoKhuseleko

Kubaluleke kakhulu ukuqaphela ukuba isisombululo se-sodium cyanide sinetyhefu kakhulu. Kwanentwana encinci inokubulala ukuba ityiwe, irhoxiwe, okanye ifunxeka eluswini. Xa idibana neeasidi okanye umoya ofumileyo, inokukhupha igesi eyityhefu yehydrogen cyanide. Ngoko ke, iiprothokholi eziqinileyo zokhuseleko kufuneka zilandelwe xa kusingathwa isisombululo se-sodium cyanide. Abasebenzi ababandakanyekileyo ekusetyenzisweni kwayo bafanele baqeqeshwe ngokufanelekileyo, banxibe izixhobo ezifanelekileyo zokuzikhusela baze basebenze kwiindawo ezinomoya owaneleyo. Kwimeko yokuchitheka ngengozi okanye ukuvezwa, iinkqubo zokusabela ngokukhawuleza ngokukhawuleza kufuneka ziphunyezwe ukuthintela ingozi enkulu kwimpilo yabantu kunye nokusingqongileyo.

Ekugqibeleni, isisombululo se-sodium cyanide, nangona inobungozi bayo, idlala indima ebalulekileyo kumashishini amaninzi. Izicelo zayo zivela kwi-extraction yentsimbi exabisekileyo kwi-chemical synthesis kunye nonyango lwetsimbi. Nangona kunjalo, iingozi ezinxulumene nazo zifuna ukuba ukusetyenziswa kwayo kulawulwe ngononophelo kwaye kulawulwe ukuqinisekisa ukhuseleko.
