Kub Ore

Ores nyob rau hauv uas kub tshwm sim nyob rau hauv cov tshuaj muaj pes tsawg leeg nrog rau lwm yam yog comparatively tsawg. Lawv suav nrog calaverite, sylvanite, nagyagite, petzite thiab krennerite.
Kub Concentrates
Kub concentrates yog muab los ntawm ob txoj kev sib txawv. Thawj yog los ntawm kub panning (los yog lwm yam txuj ci uas siv lub ntiajteb txawj nqus sib cais). Thaum panning rau kub, lub hom phiaj yog cais cov khoom ntawm cov av los ntawm cov khoom hnyav ntawm kub. Feem ntau, txawm li cas los xij, kub tsis yog tsuas yog cov khoom hnyav hauv lub lauj kaub. Qhov kawg tshwm sim ntawm cov txheej txheem panning yog kub concentrates - uas yuav tsum tau sifted los ntawm manually kom rho tawm cov khoom kub. Kub concentrates feem ntau yog hlau, yog li lawv kuj hu ua "dub xuab zeb."
Kub concentrates kuj yog tsim los ntawm kev sib tsoo cov ore, quartz, los yog lwm yam pob zeb tsim rau hauv cov xuab zeb. Cov txheej txheem no sai dua thiab yooj yim dua li panning, tab sis kev lag luam tawm yog cov khoom kawg uas tsis muaj kub "sib xyaws" hauv. Cov nyiaj them av tau ntim nrog cov khoom siv panning lossis muag raws li cov khoom plig hauv cov nroog kub kub feem ntau yog los ntawm txoj kev sib tsoo no.

Kub Extraction

Kev rho tawm kub yog hais txog cov txheej txheem uas yuav tsum tau rho tawm kub los ntawm nws cov ore. Qhov no yuav xav tau kev sib xyaw ua ke, kev ua cov ntxhia, hydrometallurgical, thiab pyrometallurgical txheej txheem yuav tsum tau ua ntawm cov ore.
Kub mining los ntawm alluvium ores yog ib zaug ua tiav los ntawm cov tswv yim txuam nrog placer mining xws li yooj yim kub panning thiab sluicing, uas ua rau ncaj qha rov qab ntawm me me kub nuggets thiab flakes. Placer mining cov txheej txheem txij li nruab nrab mus rau lig xyoo pua 20th feem ntau tsuas yog kev coj ua ntawm cov neeg ua haujlwm mining. Hydraulic mining tau siv dav hauv Californian kub maj, thiab koom nrog kev rhuav tshem cov pob zeb hauv av nrog cov dav hlau siab ntawm cov dej. Cov pob zeb tawv pob zeb tau tsim lub hauv paus ntawm feem ntau ntawm kev lag luam kub rov ua haujlwm txij li nruab nrab ntawm lub xyoo pua 20th uas qhib lub qhov thiab los yog cov txheej txheem mining sub-dog.
Thaum cov ore raug mined nws tuaj yeem kho tau tag nrho cov ore siv cov pob tseg leaching lossis heap leaching txheej txheem. Qhov no yog ib qho ntawm cov qib qis, oxide deposits. Feem ntau, cov ore yog crushed thiab agglomerated ua ntej heap leaching. Qib siab ore thiab ores resistant rau cyanide leaching ntawm coarse particle qhov ntau thiab tsawg, yuav tsum tau ua ntxiv nyob rau hauv thiaj li yuav rov qab tau cov nqi kub. Cov txheej txheem kev ua haujlwm tuaj yeem suav nrog kev sib tsoo, kev xav tau, ci, thiab siab oxidation ua ntej cyanidation.
