Uhlalutyo olufutshane lwendima ye-copper sulfate kwi-ore beneficiation kunye ne-flotation

I-Copper sulfate, ebonakala njengeekristale ezibhlowu okanye eziluhlaza-luhlaza, sisixhobo esisetyenziswa ngokubanzi kwi-ore flotation ye-sulfide.Isetyenziswa kakhulu njenge-activator, i-regulator kunye ne-inhibitor ukulungelelanisa ixabiso le-pH ye-slurry, ukulawula ukuveliswa kwe-foam kunye nokuphucula I-surface potential of minerals ine-activation effect kwi-sphalerite, i-stibnite, i-pyrite kunye ne-pyrrhotite, ngakumbi i-sphalerite evinjelwa yi-lime. okanye icyanide.

Indima yesulfate yobhedu kwi-mineral flotation:

1. Isetyenziswa njenge activator

Unokutshintsha iimpawu zombane zemiphezulu yezimbiwa kwaye wenze imiphezulu yeminerali ibe yihydrophilic.Le hydrophilicity inokunyusa indawo yoqhagamshelwano phakathi kweminerali kunye namanzi, okwenza kube lula ukuba iminerali idada.I-Copper sulfate inokwenza i-cations kwi-slurry yamaminerali, ethe yabhengezwa ngakumbi kumphezulu weminerali, inyusa i-hydrophilicity yayo kunye ne-buoyancy.

Indlela yokuvula ibandakanya le miba mibini ilandelayo:

①.Ukusabela kwemetathesis kwenzeka kumphezulu weminerali esebenzayo ukwenza ifilimu yokuvula.Ngokomzekelo, i-sulfate yethusi isetyenziselwa ukwenza i-sphalerite isebenze.I-radius ye-ion ye-copper ye-divalent ifana ne-radius ye-zinc ion, kunye ne-solubility ye-sulfide yobhedu incinci kakhulu kune-zinc sulfide.Ngoko ke, ifilimu ye-sulfide yethusi inokuqulunqwa kumphezulu we-sphalerite.Emva kokuba ifilimu ye-sulfide yobhedu yenziwe, iyakwazi ukusebenzisana ngokulula nomqokeleli we-xanthate, ukwenzela ukuba i-sphalerite isebenze.

②.Susa inhibitor kuqala, kwaye wenze ifilimu yokuvula.Xa i-sodium cyanide inqanda i-sphalerite, i-zinc cyanide ion ezizinzile zenziwe phezu kwe-sphalerite, kunye ne-copper cyanide ions zizinzile ngakumbi kune-zinc cyanide ions.Ukuba i-sulfate yethusi yongezwa kwi-sphalerite slurry enqatshelwe yi-cyanide, i-cyanide radicals ebusweni be-sphalerite iya kuwa, kwaye i-ion yobhedu yamahhala iya kusabela kunye ne-sphalerite ukwenza ifilimu yokuvula i-copper sulfide, ngaloo ndlela isebenze. sphalerite.

2. Isetyenziswe njengomlawuli

Ixabiso le-pH le-slurry lingalungiswa.Ngexabiso elifanelekileyo le-pH, i-copper sulfate inokusabela ngee-ion ze-hydrogen kumphezulu wezimbiwa ukuze zenze izinto zekhemikhali ezidityaniswa nomphezulu weminerali, zinyusa i-hydrophilicity kunye ne-buoyancy yezimbiwa, ngaloo ndlela ikhuthaza isiphumo sokudada kwimigodi yegolide.

3. Isetyenziswe njenge-inhibitor

I-Anions inokwakheka kwi-slurry kunye ne-adsorbed kumphezulu wezinye izimbiwa ezingadingi ukudada, ukunciphisa i-hydrophilicity kunye ne-buoyancy, ngaloo ndlela ithintela ezi zimbiwa ukuba zidada kunye neeminerali zegolide.I-Copper sulfate inhibitors zihlala zongezwa kwi-slurry ukugcina iiminerali ezingadingi ukujikeleza ezantsi.

4. Isetyenziswa njengesilungisi somgangatho weminerali

Guqula iipropathi zekhemikhali kunye nezomzimba kwimiphezulu yezimbiwa.Kwiflotation yegolide, iipropathi zombane kunye ne-hydrophilicity yendawo yezimbiwa zizinto eziphambili zokudada.I-sulfate ye-Copper inokwenza i-ion ye-copper oxide kwi-slurry yamaminerali, iphendule ngee-ion zetsimbi kumphezulu we-mineral, kwaye iguqule iipropati zayo zemichiza.I-Copper sulfate inokutshintsha kwakhona i-hydrophilicity ye-mineral surfaces kwaye yandise indawo yoqhagamshelwano phakathi kweeminerali kunye namanzi, ngaloo ndlela ikhuthaza umphumo wokujikeleza kwemigodi yegolide.
