Taw qhia rau Antimony Ore Processing
Antimony (Sb) yog ib qho xim grey metalloid, feem ntau yog siv los ua cov khoom tawv tawv rau cov hlau lead, tshwj xeeb tshaj yog nyob rau hauv cov hlau lead -acid roj teeb. Nws cov trioxide yog ib qho tseem ceeb ntawm cov nplaim hluav taws kub nyhiab hauv plastics thiab textiles. Antimony ore beneficiation thiab extraction yog complex vim lub ntxhia lub brittleness thiab qhov tseeb hais tias nws feem ntau tshwm sim nyob rau hauv complex ores nrog rau lwm yam hlau xws li txhuas, tooj liab, thiab nyiaj.
Cov txheej txheem tshwj xeeb thiab cov tshuab siv yog nyob ntawm qhov hnyav ntawm cov ore muaj pes tsawg leeg (xws li, stibnite, antimonial kub) thiab qib.
Core Processing Stages & Machinery
Ib hom antimony ore ua cov nroj tsuag ua raws li cov theem tseem ceeb no:
Kauj Ruam 1: Sib tsoo thiab sib tsoo (kev sib txuas lus)
Lub hom phiaj yog los tso cov antimony -cov khoom muaj nqis los ntawm gangue (pob zeb pov tseg).
Primary Puab Crusher:Cov khiav- ntawm- kuv (ROM) ore yog pub rau hauv lub puab tsaig hnyav - lub puab tsaig crusher. Lub tshuab no txo cov pob zeb loj (txog 1 meter) mus rau qhov loj me me ntawm 100-200 hli.
Tshuab Hom:Blake Puab Tsaig Crusher, Overhead Eccentric Puab Tsaig Crusher.
Secondary Cone Crusher:Cov zis los ntawm lub puab tsaig crusher yog ntxiv txo los ntawm lub khob hliav qab crusher mus rau qhov loj ntawm ib ncig ntawm 10-50 mm.
Tshuab Hom:Caij nplooj ntoos hlav Cone Crusher, Hydraulic Cone Crusher.
Sib tsoo zeb:Tom qab ntawd cov crushed ore yog muab tso rau hauv ib lub zeb sib tsoo nrog dej los tsim ib tug slurry. Lub zeb siv cov pob steel lossis cov ore nws tus kheej ua cov xov xwm sib tsoo kom txo cov particle loj rau cov hmoov zoo (feem ntau tsawg dua 0.1 hli), zoo liberating antimony minerals.
Tshuab Hom:
Pob Zeb:Feem ntau.
Qws Mill:Qee zaum siv rau coarser pib sib tsoo.
Theem 2: Kev Pabcuam (Lub ntiajteb txawj nqus sib cais & Flotation)
Qhov no yog theem tseem ceeb tshaj plaws rau kev tsom mus rau antimony.
Rau Yooj Yim, Coarse-Grained Ores:
Kev sib cais ntawm lub ntiajteb txawj nqus:Txoj kev no exploits lub siab lub ntiajteb txawj nqus ntawm stibnite (lub ntsiab antimony ntxhia).
Jig tshuab:Lub tshuab siv tau zoo. Lub slurry yog pulsed vertically ntawm ib qho screen, ua rau denser antimony hais nyob rau hauv qab thiab sib dua gangue yuav tsum tau ntxuav tawm.
Jig Tshuab
Shaking Table:Ib me ntsis inclined rooj nrog riffles. Raws li lub rooj shakes, lub denser antimony concentrate txav raws cov riffles thaum lub teeb tailings raug ntxuav tawm ntawm sab.
Rau Complex, Fine-Grained Ores (Feem ntau):
Froth Flotation:Qhov no yog txoj hauv kev zoo tshaj plaws rau kev rov qab los ntawm antimony. Nws cais cov zaub mov raws li lawv qhov chaw chemistry.
Conditioning Tank:Cov av ore slurry yog tov nrog cov reagents tshwj xeeb.
Cov neeg sau khoom (piv txwv li, Xanthates):Ua kom cov pob zeb hauv av antimony hydrophobic (dej{0}}repelling).
Frothers (eg, Pine Oil):Tsim cov npuas ruaj khov hauv cov flotation cell.
Activators / Depressants:Siv los xaiv cais antimony los ntawm lwm cov zaub mov sulfide (xws li txhuas lossis tooj liab).
Flotation Cell / Mechanism:Cua yog cua tshuab rau hauv lub tank, tsim npuas. Cov hydrophobic antimony particles txuas rau cov npuas thiab nce mus rau saum npoo los ua ib qho froth. Qhov no froth yog skimmed tawm limloog zoo. Cov dej hydrophilic (dej-) attracting) gangue particles sink thiab raug tso tawm raws litailings.
Tshuab Hom:Mechanical Agitation Flotation Cell, Pneumatic Flotation Cell, Kem Flotation Cell.
Feem ntau, kev sib xyaw ua ke ntawm lub ntiajteb txawj nqus ua ntej- kev sib xyaw ua raws los ntawm flotation yog siv los kho kom zoo thiab qib.
Theem 3: Dewatering
Cov concentration ntawm flotation los yog gravity Circuit Court yog slurry nrog cov ntsiab lus dej siab. Cov dej no yuav tsum tau muab tshem tawm rau kev thauj mus los thiab ua haujlwm ntxiv.
Thickener:Ib lub tank loj loj uas cov slurry yog pub rau hauv qhov chaw. Flocculants tau ntxiv los ua kom cov khoom zoo sib xyaw ua ke thiab khom rau hauv qab raws li cov sludge tuab (underflow). Cov dej ntshiab ntws mus rau saum toj thiab feem ntau siv rov qab rau hauv cov nroj tsuag.
Filter Press lossis Vacuum Disk Filter:Lub thickened sludge yog pumped mus rau lub lim.
Lim Xovxwm:Siv lub zog siab los nyem dej tawm los ntawm cov ntaub lim dej, ua kom qhuav, khoom lim ncuav mog qab zib (cov ntsiab lus noo noo ~ 10-20%).
Nqus Disk Filter:Lub tshuab txuas ntxiv uas siv lub tshuab nqus tsev los kos cov dej los ntawm kev sib hloov cov disks npog hauv cov ntaub lim dej, tsim cov ncuav mog qab zib me ntsis ntub dej.
Theem 4: Pyrometallurgical Processing (Smelting)
Lub ncuav mog qab zib lim (antimony concentrate) raug xa mus rau lub smelter rau hlau ntau lawm. Qhov no feem ntau yog ib qho chaw sib cais.
Ci rauv:Cov concentrate tuaj yeem ua ntej ci kom tshem tawm cov sulfur thiab hloov mus rau antimony oxide (Sb₂O₃).
Reverberatory Rauv los yog Blast Furnace:Cov oxide los yog raw cov ntsiab lus yog smelted nrog ib tug txo tus neeg sawv cev (xws li coke / thee) thiab fluxes (xws li dej qab zib tshauv los yog sodium sulfate) los tsim crude antimony hlau (feem ntau hu ua "Crude antimony" los yog "liquated" antimony).
Refining Kettle / Ladle:Cov hlau tsis huv yog ua kom zoo dua los ntawm kev ntxiv cov fluxes tshwj xeeb kom tshem tawm cov impurities xws li hlau, arsenic, thiab sulfur, ua rau kev lag luam - qib antimony hlau.

Cov ntsiab lus tseem ceeb rau kev cog qoob loo
Ore Variability:Cov nroj tsuag tsim yuav tsum yoog raws li kev hloov pauv hauv qib ore thiab mineralogy.
Environmental Controls:Stibnite (Sb₂S₃) muaj sulfur, uas tsim cov sulfur dioxide (SO₂) thaum smelting. Cov nroj tsuag niaj hnub xav tau kev ua haujlwm zoogas tu tshuabzoo li cov nroj tsuag kua qaub los yog cov tshuaj txhuam hniav kom tsis txhob muaj pa phem.
Kev Tswj Dej:Dej yog siv dav thiab yuav tsum tau siv dua.Tailings damsyuav tsum tau ua tib zoo tsim kom tsis txhob muaj kab mob hauv av.
Reagent Optimization:Hom thiab ntau npaum li cas ntawm cov flotation reagents yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo thiab cov qib siab. Qhov no yuav tsum muaj ib qho chaw zoo -nrog rau kev sim mus tas li.
Nyob rau hauv cov ntsiab lus, antimony ore ua cov nroj tsuag yog ib tug complex system ntawm hnyav -lub luag hauj lwm crushers, precision sib tsoo mills, sophisticated flotation hlwb, thiab robust dewatering cov cuab yeej, tag nrho cov tswj kom zoo sib cais thiab mloog zoo ib tug tseem ceeb tab sis feem ntau dag hlau los ntawm nws cov ore.
