Lead nitrate yog cov tshuaj siv dav siv hauv ntau lub lag luam, suav nrog kev tsuas.Nws cov khoom siv ntau yam ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau daim ntawv thov hauv mining sector.Hauv tsab xov xwm no, peb yuav tshawb txog cov laj thawj vim li cas cov hlau lead nitrate nyiam hauv kev ua haujlwm tsuas thiab nws cov txiaj ntsig tseem ceeb.
Ib qho ntawm cov kev siv tseem ceeb ntawm cov hlau lead nitrate hauv kev tsuas yog nws lub luag haujlwm ua tus activator hauv cov txheej txheem flotation.Flotation yog txheej txheem siv los cais cov pob zeb muaj txiaj ntsig los ntawm cov pob zeb nyob ib puag ncig.Lead nitrate ua raws li ib tug catalyst, txhim khu kev ua tau zoo ntawm cov txheej txheem no los ntawm kev txhim kho cov nqi rov qab ntawm cov hlau zoo xws li nyiaj thiab kub.Ntxiv cov hmoov lead nitrate rau hauv lub flotation cell pab tsim kom muaj qhov ruaj khov froth, ua kom yooj yim rau kev xaiv kev sib cais ntawm cov zaub mov muaj txiaj ntsig los ntawm gangue hais.
Tsis tas li ntawd, txhuas nitrate tseem tiv thaiv kev cuam tshuam ntawm pyrite, lossis hu ua "fool's gold," hauv cov txheej txheem flotation.Pyrite tuaj yeem cuam tshuam tsis zoo rau kev rov qab los ntawm cov zaub mov muaj txiaj ntsig los ntawm kev noj cov pa ntau dhau thiab ua rau cov kua qaub.Los ntawm oxidizing pyrite, lead nitrate counteracts nws cov teeb meem cuam tshuam, ua rau kom zoo dua flotation kev ua tau zoo thiab ntxiv cov ntxhia rov qab.
Lead nitrate tsis yog tsuas yog ua haujlwm zoo hauv kev txhim kho cov txheej txheem flotation tab sis kuj tseem tiv thaiv kev tsim ntawm cyanide-resistant kub hais.Hauv kev rho tawm kub siv cyanide, qee cov ores yuav muaj cov kub refractory uas nyuaj rau rho tawm.Txawm li cas los xij, los ntawm kev ntxiv cov hmoov lead nitrate, kev tsim cov tshuaj insoluble uas cuam tshuam cov kub dissolution tuaj yeem tiv thaiv tau, yog li ua kom cov nyiaj rov qab tau zoo heev.
Cov khoom tawg ntawm cov hlau lead nitrate kuj muaj txiaj ntsig zoo hauv kev ua haujlwm mining.Nws yog ib qho tseem ceeb ntawm cov khoom tawg uas siv rau blasting pob zeb thiab ore.Lead nitrate ua raws li sensitizer, ua rau cov khoom tawg yooj yim dua thiab xa cov zog tsim nyog los rhuav tshem geological formations.Nws ruaj khov thiab kev sib raug zoo nrog lwm yam khoom ua rau nws muaj kev ntseeg siab thiab muaj kev nyab xeeb rau kev ua haujlwm blasting.
Tsis tas li ntawd, txhuas nitrate pom zoo solubility hauv dej, ua kom yooj yim rau ntau yam kev siv mining.Nws solubility tso cai rau kev tuav tau yooj yim thiab raug muab tshuaj hauv cov txheej txheem sib txawv.Kev txhim khu kev qha ntawm cov hmoov txhuas nitrate ua kom cov txiaj ntsig zoo ib yam thiab txo qhov kev hloov pauv hauv cov txheej txheem tsim khoom, ua rau kev ua haujlwm zoo tag nrho.
Qhov kev nyab xeeb ntawm cov hlau lead nitrate yog qhov tseem ceeb heev rau kev ua haujlwm mining.Thaum nws yog ib qho tseem ceeb los tswj tag nrho cov tshuaj nrog kev saib xyuas, txhuas nitrate yog qhov ruaj khov thaum khaws cia thiab kho kom raug.Nws tsis tshua muaj flammability thiab tsis-reactive xwm ntawm ntau yam tshuaj pab txhawb rau nws txoj kev nyab xeeb siv nyob rau hauv mining ib puag ncig.
Hauv kev xaus, txhuas nitrate muaj ntau yam zoo uas ua rau nws xaiv zoo rau ntau yam kev siv mining.Nws lub luag haujlwm ua tus flotation activator, nws lub peev xwm los tiv thaiv qhov cuam tshuam ntawm pyrite, thiab nws cov txiaj ntsig hauv kev tawm tsam kev tsim cov cyanide-resistant kub hais ua rau nws muaj txiaj ntsig zoo hauv cov txheej txheem ntxhia extraction.Tsis tas li ntawd, nws cov khoom tawg, solubility hauv dej, thiab kev nyab xeeb tag nrho ua rau nws siv dav hauv kev lag luam mining.Los ntawm kev xaiv cov hmoov lead nitrate, cov neeg ua haujlwm mining tuaj yeem txhim kho kev ua haujlwm zoo, txhim kho cov ntxhia rov qab, thiab ua kom muaj kev nyab xeeb ua haujlwm.
