Indlela ehlanganisiwe ye-Assay kumele inqunywe ngokuya ngohlobo lwesampula, futhi inani le-reagents ehlukahlukene elingeziwe kufanele libalwe ngokuya ngobubanzi obudingekayo be-acidionity. Futhi amasampula nawo awabeka encafeni futhi avuse ama-reagents namasampula ngesipuni esishukumisayo, futhi anikine ngobumnene ukwenza izinhlayiya ezincane zinamathiselwe odongeni olungaphakathi lwe-Earnible.

Uma iqukethe isibabule, faka izinzipho zensimbi ezidingekayo bese ufaka ungqimba we-ejenti ye-alend. Lapho amazinga okushisa esithandweni sikagesi akhuphukela ku-800 ° C, okubaleka ngezinto zokwakha kufakwa esithandweni somlilo, futhi izinga lokushisa lomlilo lenyuke laya ku-1150 ° C kungakapheli imizuzu eyi-1.

Ngenxa yezinhlobo ezahlukene ze-ore, indlela yokuthola izithako zegolide ezihlangene futhi. Ngokusho kohlobo lwe-ore kanye nezithako, kunezindlela ezintathu zezithako ngendlela enokwehla kwe-ebertible: indlela yefulawa, indlela ye-sodium nitrate-coke noma indlela yensimbi, indlela yensimbi.


1. Indlela yefulawa yindlela esetshenziswa kakhulu yokuthathwa. Lapho isampula ngokwalo alinamandla noma anciphise kakhulu, ufulawa udinga ukungezwa njengomenzeli oncishisiwe. Le ndlela inezinzuzo eziningi. Ingalawula usayizi wenkinobho yokuhola. Inobubanzi obuhlukahlukene bamaminerali nezinto zokwakha, futhi ilungele i-are are, carbonate ore ne-ore ore. I-ore ebilisiwe ngemuva kokutholwa kwe-sulfide ore ukususa i-sulfur nakho kungasetshenziswa kule ndlela.

Izidingo zokuvalwa kwamasampula asuselwe ore are-based yile:

(1) I-acidity ye-silicic of the slag ingu-1.5-20;

(2) isisindo esingu-30-50g sesampula;

(3) Faka i-sodium carbonate njengenani lesampula;

(4) Inani le-borax elingeziwe lingu-0.2 kuya ku-0.3 izikhathi zesampula;

(5) Inani le-Exhol Oxide akufanele libe ngaphansi kwesisindo senkinobho yokuhola.

(6) Inani likafulawa kufanele lilingane no-30- (usayizi wesampula × isampula ukunciphisa amandla amandla) / 12.

I-okili ore ne-carbonate yiminerali ye-alkaline, futhi indlela yabo yokuhlanganisa ngokuyisisekelo iyafana naleyo yamasampula athulayo. Umehluko ukuthi imikhiqizo ngemuva kokubhema kakhulu izinto ze-alkaline ezifana ne-CAO, MGO, Feo, ngakho-ke inani elikhulu le-SIO2 kufanele lingezelwe noma kunjalo, i-CASTIOM2, kanye neCasio2 ephezulu. Inani le-PBO kufanele lenyuswe kwizithako ukuze likhulise ukwakheka kwe-PBSO2 ku-SLAG futhi kunciphise izinga lokuncibilika.


2. Indlela Yezipikili Yensimbi (i-sodium nitrate-coke indlela) Indlela yezipikili zensimbi ayilungele ithusi le-sulfide are liqukethe ithusi elithe xaxa, i-nickel, i-arsenic kanye ne-antimony, kepha isetshenziselwa umgomo oyisisekelo wamasampula we (ZNS) kanye ne-pyrite (i-Fes2) ukusebenzisa insimbi yensimbi njenge-ejenti yokuhlaselwa ukubola i-sulfide kusampula, futhi kwakha ama-sulfide, bese usebenzisa i-FES noma i-FE (ⅱ) -Indlela yokufaka i-slag, kanye I-Iron Nail futhi isebenza njengomenzeli oncishisiwe, ukunciphisa ukuhola ookide kuya ekuholeni kwensimbi, kanye nokushaya izinsimbi eziyigugu. Uma isampula liqukethe ithusi, i-nickel, i-arsenic, i-antimony, i-bismuth nezinye izinsimbi ku-oda lokunciphisa ngaphambi kwensimbi, faka inkinobho yensimbi, faka i-alloy eholayo. Ngakho-ke le ndlela ayilungele amasampula anjalo.

Izithako zenqubomgomo yendlela yezipikili:

(1) I-acidity silicic ye-molten slag ingu-0,5;

(2) Inani le-sodium carbonate lihlabe izikhathi ezi-2 kuya kwezi-3;

(3) Inani le-Exhol Oxide lingu-30 kuye ku-35 g;

(4) ) Inani le-borax elingeziwe liyi-1/2 kuya ku-1/3 yesampula yesampula;

(5) Inani lesampula lingama-20 kuye ku-30g.


I-3.SaltypePepere iyindlela yokuvalwa kokufaka amasampula ngamandla aqine anciphisa. I-oxidation of potassium nitrate isetshenziselwa ukwenza buthaka amandla okunciphisa kusampula, ukuze uthole inkinobho yokuhola ngesisindo esifanele, ukuze umphumela wokuthumba izinsimbi eziyigugu muhle

Izithako zenqubo ye-Saltpeter:

(1) Amandla okunciphisa kwesampula kumele alinganiswe ngaphambi kwezithako ukuthola inani le-potassium nitrate engezwe. I-Saltpeter akufanele idlule i-25G.

.

.

(4) Inani le-Move Oxide elengeziwe lihlale izikhathi eziyi-12 kuye kwezingu-14 ukunciphisa inani lesampula. Amandla anciphisa ngaphezulu kwama-30 angamahlandla ayi-12, kanye namandla ancishisiwe ngaphansi kwama-30 amahlandla ayi-14.

(5) Umthamo weBorax akaphansi kwe-5G.

.

Kuyadingeka ukusebenzisa indlela yokubala yokwenza izithako emsebenzini we-assy, ​​kepha emsebenzini wangempela, kuvame ukuba nzima ukwazi okuqukethwe kwesampula okuthunyelwe kwamehlo nangokuhlangenwe nakho. Okokuqala bheka umbala kanye nekhwalithi yesampula, inqume ukuthi yiluphi uhlobo lwe-ore olungelona, ​​bese unquma ukuthi iyiphi indlela ye-Assay ongayisebenzisa.
