Maitiro ekugadzirisa Sodium Cyanide Dosage zvinoenderana neOre Particle Size?

Munyaya dzekugadzirisa zvicherwa, kunyanya mukuita kuti goridhe nesirivha zvicherwe, kugadzirisa dosage yeSodium Cyanide zvichienderana nehukuru hwezvimedu zveore kwakakosha pakuvandudza mashandiro ekubvisa tsvina uye kuderedza mari yekugadzira. Chinyorwa chino chine chinangwa chekupa gwara rakazara rekuti ungagadzirisa sei zvinhu zvakadaro.

Iyo Kufurira Mechanism yeOre Particle Saizi paCyanidation Reaction

Surface Area uye Reaction Kinetics

Zvidimbu zveore zvakapfava zvine nzvimbo yakakura yepamusoro. Kana sodium cyanide solution ikasangana neore, nzvimbo yakakura yepamusoro inobvumira nzvimbo dzakawanda dzekubatana pakati peiyoni yecyanide nezvicherwa zvinotarirwa (senge goridhe kana sirivha). Zvichienderana nedzidziso ye reaction kinetics, chiyero che reaction chinoenderana nenzvimbo yepamusoro ye reactants. Semuenzaniso, muchidzidzo che gold cyanidation, zvakaonekwa kuti apo saizi yechinhu cheore yakaderedzwa kubva pahukuru hwakakora kusvika -38 μm ine chiyero chemukati che75%, chiyero che leaching chegoridhe chakawedzera zvakanyanya. Nezvidimbu zvakapfava, maatomu egoridhe akawanda pamusoro anoiswa pachena kune iyoni yecyanide, zvichiita kuti reaction ishande zvakanaka.

Coarser particles, kune rumwe rutivi, ane nzvimbo diki yepamusoro inowanikwa kuti iite. Iyo cyanide ion inokwanisa chete kuita nekunze kweiyo zvidimbu, uye kupararira kweiyo cyanide mukati memukati meiyo yakakora kunonoka. Izvi zvinotungamira kune yakaderera chiyero chekuita uye kusakwana leaching yemaminerari anonangwa mukati mezvimedu.

Diffusion Barrier

Kana ari maore akacheneswa, chinhambwe chinoda kupararira neiyo cyanide kuti isvike kune zvicherwa chipfupi. Izvi zvinoderedza kupararira kwekudzivirira uye zvinogonesa kuita nekukurumidza. Sezvo saizi ye ore ichiwedzera, nzira yekupararira ye cyanide ions kuburikidza ne porous chimiro che ore particles inova yakareba. Kuvapo kwemaminerari e gangue muzvikamu zvinogonawo kuita sechivharo chekuparadzira. Semuyenzaniso, kana paine akaturikidzana ezvicherwa zve-non-reactive gangue zvakatenderedza goridhe - zvine zvicherwa muchikamu chakakasharara, zvinotora nguva yakareba kuti ion cyanide ipinde uye kuita negoridhe, zvichikonzera kudzikira kwekudzikira.

Kuyerwa kweOre Particle Size

Sieving Analysis

Sieving inzira yakajairika uye yakatwasuka yekuona ore particle size. Seti yemasefa akajairwa ane masaizi akasiyana mesh anoshandiswa. Sample ore inoiswa pamusoro pesefa yestack, uye ipapo staki yacho inozununguswa nemichina kwenguva yakati. Zvimedu zvinopfuura nepasefa imwe neimwe zvinounganidzwa uye zvinoyerwa. Nekuverenga huwandu hwehuwandu hwezvimedu zvakachengetwa pasefa yega yega, kugoverwa kwesaizi yesamu yeore inogona kuwanikwa. Semuyenzaniso, muchigadzirwa chegoridhe chekugadzira ore, kana simbi yakapepetwa nepakati pemasefa ane mesh size 200. 325. uye 400. chikamu chezvikamu zviduku kudarika mesh size imwe neimwe inogona kugadziriswa, iyo inobatsira mukunzwisisa kunaka kwesimbi.

Laser Diffraction Particle Size Analysis

Iyi inzira yepamusoro uye yakarurama. Laser diffraction analyzers inoshanda zvichibva pamusimboti wekuti kana danda relaser richipfuura nepakaparadzirwa particle system, zvimedu zvinoparadzira mwenje welaser. Kona uye kusimba kwechiedza chakapararira zvine chekuita nekukura kwechidimbu. Nekuyera mwenje wakapararira, chiridzwa chinogona kuverenga kugoverwa kwesaizi ye ore sampuli. Inogona kupa ruzivo rwakadzama nezvese particle size renji, kusanganisira zvimedu zvakanakisa zvingave zvakaoma kuyera nemazvo nekusefa. Iyi nzira inonyanya kubatsira kana uchibata neores ine huwandu hwakasiyana hwehukuru hwezvikamu kana kana yakakwirira-chaiyo kuyerwa kunodiwa pakugadzirisa cyanidation maitiro.

Nheyo uye Nzira dzekugadzirisa Sodium Cyanide Dosage

General Misimboti

Proportional Relationship mukati meImwe Range

Kazhinji, mukati mechikamu chakati, huwandu hweSodium cyanide inowedzerwa hunoenderana nenzvimbo yepamusoro pezvikamu zveore. Sezvo saizi yezvikamu zveore ichiva diki (nzvimbo yakakura), sodium cyanide yakawanda inodiwa kuti ive nechokwadi chekuti zvinoitwa nemaminerari anotarisirwa. Zvisinei, hukama uhwu hahuna kurongeka zvachose. Kana huwandu hwesodium cyanide hukadarika imwe nhanho, kushanda kwekubvisa makemikari kunogona kusawedzera zvakanyanya, uye zvinokonzeresa kutambisa makemikari uye kuwedzera mari yekugadzira.

Ore Hunhu Kufungwa

Mhando dzakasiyana dze ores dzine akasiyana makemikari anoumbwa uye zvimiro. Mamwe ores anogona kunge aine zvicherwa zvinodya cyanide ions, senge mamwe maminerari e sulfide. Mumamiriro ezvinhu akadaro, kunyangwe kune imwechete saizi diki, yakawanda sodium cyanide inogona kudiwa kuti uwane inodiwa leaching maitiro. Semuenzaniso, kana ore ine chikamu chepamusoro che pyrite, pyrite inogona kuita ne cyanide ions uye oksijeni mumhinduro, ichidya cyanide. Saka, iyo cyanide dosage inoda kugadziridzwa zvinoenderana neiyo chaiyo mineral inoumbwa neore.

Kugadzirisa Nzira

Kuedzwa kweLabhoritari

Pamberi pekugadzirwa kwemaindasitiri makuru, bvunzo dzemurabhoritari dzinofanira kuitwa. Gadzirirai sampuli dzematombo ane saizi dzakasiyana dzezvimedu kuburikidza nekukuya nekusefa. Wobva waita bvunzo dzecyanidation leaching pasampuli idzi nechiyero chakasiyana chesodium cyanide. Yera chiyero chekubuda kwezvicherwa (semuenzaniso, goridhe kana sirivha) mumamiriro akasiyana. Nekuongorora data rekuyedza, gadzira hukama pakati pehukuru hwezvimedu zvematombo, chiyero chesodium cyanide , uye chiyero chekubuda kwezvimedu. Semuenzaniso, kune goridhe rine saizi yezvikamu zve -200 mesh (inenge 74 μm), bvunzo yerabhoritari inogona kuratidza kuti kana chiyero chesodium cyanide chawedzerwa kubva pa1 kg/t kusvika pa2 kg/t, chiyero chekubuda kwegoridhe chinowedzera kubva pa70% kusvika pa85%, asi kuwedzera chiyero kusvika pa3 kg/t kunongowedzera chiyero chekubuda kwezvimedu kusvika pa87%. Data iri rinogona kushandiswa sereferensi yekugadzira maindasitiri.

Online Monitoring uye Kugadziriswa muIndasitiri Kugadzirwa

Mukugadzirwa kwemaindasitiri, online particle size analyzers inogona kuiswa kuti irambe ichitarisisa saizi yeore inopinda mucyanidation process. Zvichienderana nehukama hwakagara hwasimbiswa pakati pesaizi saizi uye sodium cyanide dosage kubva murabhoritari bvunzo, otomatiki dosing system inogona kugadziriswa munguva chaiyo. Semuenzaniso, kana iyo online particle size analyzer ikaona kuti avhareji saizi yeore yave yakatsetseka, iyo otomatiki dosing system inogona kuwedzera iyo sodium cyanide dosage zvichienderana kuchengetedza yakakwana leaching kunyatsoita.

Mukupedzisa, kugadzirisa iyo sodium cyanide dosage maererano neore particle size ibasa rakaoma asi rinokosha mukuita cyanidation. Nekunzwisisa maitiro ekuita kwesaizi yeore particle size, kunyatsoyera ukuru hwechidimbu, uye nekutevera misimboti yakakodzera yekugadzirisa uye nzira, indasitiri yekugadzira zvicherwa inogona kuvandudza mashandiro ecyanidation leaching, kuderedza kushandiswa kwemakemikari, uye kuwedzera huwandu hwehupfumi uye nharaunda mabhenefiti.
