Itọsọna okeerẹ si Awọn olutọpa Flotation ni Flotation Ejò

Awọn reagents flotation jẹ pataki ni yiya sọtọ awọn ohun alumọni bàbà ti o niyelori lati apata egbin lakoko ilana fifa omi. Ibi-afẹde akọkọ ti flotation bàbà ni lati ṣe agbejade ifọkansi Ejò ti o ni ọja. Lati ṣaṣeyọri eyi, ọpọlọpọ awọn reagents ni a lo, ni igbagbogbo pin si awọn ẹka akọkọ mẹrin: awọn agbowọ, àwọn ará, pH modifiers, ati dispersants.

1. Ejò Flotation-odè

Awọn olugba ṣe ipa to ṣe pataki ni fifẹ bàbà nipa sisopọ si oju awọn ohun alumọni bàbà, ṣiṣe wọn ni hydrophobic. Eyi ngbanilaaye awọn ohun alumọni bàbà lati faramọ awọn nyoju afẹfẹ ati dide si oke ti sẹẹli flotation. Awọn agbasọpọ ti o wọpọ fun fifo bàbà pẹlu xanthates ati dithiophosphates (awọn reagents dudu).

• Xanthates
  Xanthates gẹgẹbi ethyl xanthate ati pentyl xanthate jẹ lilo pupọ Ejò flotation-odè. Wọn fe ni adsorb pẹlẹpẹlẹ awọn dada ti Ejò awọn ohun alumọni, ṣiṣe awọn wọn hydrophobic ati bayi rọrun lati so si air nyoju ninu awọn flotation cell.

• Dithiophosphates (Awọn ohun elo dudu)
  Dithiophosphate reagents bi sodium diisobutyl dithiophosphate (dudu sodium reagent) ati ammonium diisobutyl dithiophosphate (dudu ammonium reagent) ni a tun lo nigbagbogbo. Wọn ṣiṣẹ bakannaa nipa imudara hydrophobicity ti awọn ohun alumọni bàbà, ni irọrun flotation daradara.

2. Frothers fun Ejò Flotation

Wọ́n máa ń fi àwọn ẹ̀gbọ́n sínú àwọn sẹ́ẹ̀lì tí ń fò kiri láti mú kí àwọn ìṣùpọ̀ tí ó dúró ṣánṣán tí ń gbé àwọn ohun alumọni bàbà hydrophobic lọ sí ojú sẹ́ẹ̀lì náà, níbi tí wọ́n ti lè ṣí wọn kúrò.

• Epo Pine
  Epo Pine jẹ ọkan ninu awọn frothers ti o wọpọ julọ ti a lo. O fọọmu kan idurosinsin froth Layer ti o mu awọn ohun alumọni Ejò si awọn dada fun gbigba.

• Methyl Isobutyl Carbinol (MIBC)
  MIBC jẹ frother olokiki miiran, ti a mọ fun awọn ohun-ini frothing ti o dara julọ ati iduroṣinṣin, eyiti o mu ṣiṣe ṣiṣe flotation dara si.

• Polyether Frothers
  Polyether agbo bi polyethylene glycol ati polypropylene glycol ti wa ni tun lo ninu Ejò flotation. Awọn frothers wọnyi pese awọn nyoju iduroṣinṣin ati atilẹyin iṣẹ ṣiṣe flotation to dara julọ.

3. pH Modifiers fun Ejò Flotation

Awọn oluyipada pH ṣe ilana awọn ipo kemikali ti flotation slurry lati mu iwọn Ejò imularada. Awọn iyipada pH ti o wọpọ pẹlu orombo wewe, sodium hydroxide, ati sulfuric acid.

• Orombo wewe ati iṣuu soda Hydroxide
  Orombo wewe ati iṣuu soda hydroxide ni a lo lati ṣatunṣe pH slurry, mimu iṣẹ ṣiṣe fifẹ bàbà ṣiṣẹ. Iṣakoso pH ti o tọ jẹ pataki fun yiyan flotation ti bàbà lati awọn ohun alumọni miiran.

• Inhibitors ati Activators
  Awọn inhibitors bi Iṣuu soda Cyanide ati imi-ọjọ ferrous ni a lo lati ṣe idiwọ awọn ohun alumọni ti aifẹ lati lilefoofo, imudarasi yiyan ti flotation bàbà. Awọn aṣiṣẹ, gẹgẹbi imi-ọjọ imi-ọjọ, ni a lo lati jẹki iṣipopada ti awọn ohun alumọni sulfide Ejò.

4. Dispersants fun Ejò Flotation

Dispersants mu awọn pinpin ti reagents ati ri to patikulu ninu awọn flotation slurry, aridaju olubasọrọ ti o dara laarin awọn Ejò ohun alumọni ati flotation reagents.

• polyacrylamides
  Polyacrylamide jẹ dispersant ti a lo lọpọlọpọ ti o ṣe iranlọwọ lati yago fun ikojọpọ patiku, aridaju ibaraenisepo reagent daradara ati fifẹ bàbà.

• Awọn Resini Ipopo
  Awọn resini iposii tun jẹ lilo nitori pipinka wọn ti o dara julọ ati awọn ohun-ini alemora, imudara ilana ilana flotation gbogbogbo.
