Awọn reagents flotation ni ilana ṣiṣan omi-sinkii irin

Ohun elo ti irin-sinkiiki yẹ ki o jẹ anfani ṣaaju ki o to le lo daradara.Ọna anfani ti a lo nigbagbogbo jẹ flotation.Niwọn bi o ti jẹ flotation, awọn kemikali flotation jẹ aibikita nipa ti ara.Atẹle jẹ ifihan si awọn reagents flotation ti a lo ninu awọn irin-orin-sinkii:
1. Lead ati zinc flotation olutọsọna: Awọn olutọsọna le pin si awọn inhibitors, activators, alabọde pH regulators, slime dispersants, coagulants and re-coagulants gẹgẹ bi ipa wọn ninu ilana flotation.Awọn olutọsọna pẹlu Orisirisi awọn agbo ogun aibikita (gẹgẹbi awọn iyọ, awọn ipilẹ ati acids) ati awọn agbo ogun Organic.Aṣoju kanna nigbagbogbo n ṣe awọn ipa oriṣiriṣi labẹ awọn ipo flotation oriṣiriṣi.
2. Asiwaju ati sinkii flotation-odè.Awọn akojo ti o wọpọ pẹlu: xanthate ati oogun dudu.Kilasi Xanthate pẹlu xanthate, xanthate esters, ati bẹbẹ lọ Kilasi nitrogen nitrogen, gẹgẹbi ethyl sulfide, ni agbara gbigba agbara ju xanthate lọ.O ni agbara gbigba ti o lagbara ti galena ati chalcopyrite, ati pe agbara gbigba pyrite rẹ jẹ iwọn.Irẹwẹsi, yiyan ti o dara, iyara flotation yiyara, ko wulo ju xanthate, ati pe o ni ipin gbigba ti o lagbara fun awọn patikulu isokuso ti awọn irin sulfide.Nigbati a ba lo ninu iyapa ti epo-lead-sulfur ratio ores, o le gba dara julọ ju xanthate.Dara ayokuro ipa.Oogun dudu Oogun dudu jẹ gbigba ti o munadoko ti awọn irin sulfide.Agbara ikojọpọ rẹ jẹ alailagbara ju ti xanthate.Ọja solubility ti dihydrocarbyl dithiophosphate ti ion irin kanna tobi ju ti xanthate ti ion ti o baamu.Oogun dudu O ni awọn ohun-ini foaming.Awọn lulú dudu ti o wọpọ ni ile-iṣẹ pẹlu: No.Lara wọn, butylammonium dudu lulú (dibutyl ammonium dithiophosphate) jẹ lulú funfun kan ti o rọrun O jẹ tiotuka ninu omi, o di dudu lẹhin itọlẹ, o si ni awọn ohun-ini foomu kan.O dara fun flotation ti sulfide ores bi Ejò, asiwaju, sinkii, ati nickel.
Ni afikun, cyanide le ṣe idiwọ sphalerite ni agbara, ati zinc sulfate, thiosulfate, bbl le ṣe idiwọ flotation ti sphalerite.
