Acid otsuka mchenga wa quartz

Mchenga wa Quartz pickling ndi pickling mwatsatanetsatane

Posankha oyeretsedwa khwatsi mchenga ndi mkulu chiyero khwatsi mchenga, n'zovuta kukwaniritsa zofunika njira ochiritsira beneficiation, makamaka chitsulo okusayidi filimu padziko mchenga wa quartz ndi chitsulo zosafunika ming'alu.Pofuna kupititsa patsogolo ubwino ndi zokolola za kuyeretsedwa kwa mchenga wa quartz, kuphatikizapo mawonekedwe a mchenga wa quartz osasungunuka mu asidi ndi kusungunuka pang'ono mu yankho la KOH, njira ya asidi leaching yakhala njira yofunikira yochitira mchenga wa quartz.

Kuchiza mchenga wa quartz ndikuthira mchenga wa quartz ndi hydrochloric acid, sulfuric acid, oxalic acid kapena hydrofluoric acid kuti asungunuke chitsulo.

Basic ndondomeko ya quartz mchenga pickling

Ndimagawaniza mafuta odzola a asidi

Matani a mchenga ayenera kupangidwa ndi 7-9% oxalic acid, 1-3% hydrofluoric acid ndi 90% osakaniza madzi;Pamafunika matani 2-3.5 a madzi, ngati madzi agwiritsidwanso ntchito, ndiye kuti matani 0,1 okha amadzi amafunikira kuyeretsa tani ya mchenga, poyeretsa mchenga, mosakayikira adzabweretsa mchenga wambiri;Kuchiza mchenga wa quartz ndikuthira mchenga wa quartz ndi hydrochloric acid, sulfuric acid, oxalic acid kapena hydrofluoric acid kuti asungunuke chitsulo.

Ⅱ Kusakaniza kwa pickling

The pickling solution amabayidwa mu tanki yowotchera ndikuwonjezedwa molingana ndi kuchuluka kwa hydrochloric acid zomwe zili pafupifupi 5% ya kulemera kwa mchenga kuonetsetsa kuti mchenga wa quartz umizidwa mumtsuko wa pickling ndipo hydrochloric acid imakhala pafupifupi 5% ya kulemera kwa mchenga.

Ⅲ mchenga wa quartz wotsuka ndi asidi
① Nthawi yothira mchenga wa quartz kuti unyowetse yankho la pickling nthawi zambiri ndi maola 3-5, kufunikira kowonjezera kapena kuchepetsa nthawi yonyowa molingana ndi khungu lachikasu la mchenga wa quartz, kapena yankho la pickling ndi mchenga wa quartz ukhoza kugwedezeka kwa kanthawi. nthawi, kutsatiridwa ndi ntchito Kutentha zida kutenthetsa njira kutentha zina, akhoza kuchepetsa pickling nthawi.

② Kugwiritsa ntchito asidi oxalic ndi alum wobiriwira monga kuchepetsa wothandizila pickling mankhwala akhoza kusintha kusungunuka kwa chitsulo, nawonso madzi, asidi oxalic, wobiriwira alum malinga ndi gawo la yankho pa kutentha kwina, quartz mchenga ndi njira mogwirizana. ndi gawo lina la kusakaniza, kuyambitsa, chithandizo kwa mphindi zingapo, yankho limasefedwa ndikuchiritsidwa pambuyo pochira.

③ Chithandizo cha Hydrofluoric acid: Zotsatira zake zimakhala zabwino ngati chithandizo cha hydrofluoric acid chikugwiritsidwa ntchito chokha, koma ndende yake ndi yayikulu.Mukagawidwa ndi sodium dithionite, madontho ochepa a hydrofluoric acid angagwiritsidwe ntchito.

Kuchuluka kwa hydrochloric acid ndi hydrofluoric acid solution adasakanizidwa mu slurry ya mchenga wa quartz nthawi yomweyo molingana ndi gawo;Itha kuthandizidwanso ndi yankho la hydrochloric acid poyamba, kutsukidwa ndikuthandizidwa ndi hydrofluoric acid, kuchitiridwa pa kutentha kwakukulu kwa maola 2-3, ndikusefedwa ndikutsukidwa.

Zindikirani:

Ngati asidi hydrofluoric ntchito asidi zilowerere quartz mchenga, zimene ndi zovuta.Kuphatikiza pa kusungunuka kwachitsulo muzofalitsa za acidic, HF imathanso kuchitapo kanthu ndi quartz yokha kuti isungunuke SiO2 ndi ma silicates a makulidwe ena pamwamba.

Komabe, izi ndizothandiza kwambiri pakuyeretsa pamwamba pa mchenga wa quartz ndikuchotsa chitsulo ndi zonyansa zina, motero hydrofluoric acid ndi yabwino pakutulutsa kwa quartz.Komabe, HF ndi yapoizoni komanso ikuwononga kwambiri, kotero kuti madzi otayira a acid amafunikira chisamaliro chapadera.

iv Acid kuchira ndi deacidification

Muzimutsuka ndi asidi otsuka quartz mchenga ndi madzi 2-3, ndiyeno neutralize ndi 0.05% -0.5% ya sodium hydroxide (caustic koloko) zamchere njira, ndi neutralization nthawi ndi za 30-60 Mphindi, ndi kuonetsetsa kuti quartz onse. mchenga ndi neutralized m'malo.pH ikafika pa alkaline, mutha kumasula sopo ndikutsuka nthawi 1-2 mpaka pH ilibe ndale.

Ⅴ Mchenga wouma wa quartz

Mchenga wa quartz uyenera kutsanulidwa ndi madzi pambuyo pochotsa asidi, ndiyeno mchenga wa quartz uyenera kuumitsidwa muzowumitsira.

Ⅵ kuwunika, kusankha mitundu ndi kuyika, ndi zina.

Zomwe zili pamwambazi ndizomwe zimapangidwira mchenga wa quartz pickling ndi leaching treatment, quartz ore mchenga uli ndi magawo ambiri m'dziko lathu, choncho pali kusiyana kwa mchenga wa quartz, kuyeretsa mchenga wa quartz kumafunikanso mavuto enieni. kusanthula, kupanga njira yoyenera yoyeretsera mchenga wa quartz.
