Minera Alamos npaj cov khoom tshiab ntawm Santana xyaum cov txiaj ntsig
Minera Alamos (TSX VENTURE: MAI) tshaj tawmrau hnub Wednesday ntxiv kev xyaum ua haujlwm los ntawm nws qhov kev xyaum ua ntu 2 ntawm Santana qhov project kub hauv Sonora, Mexico.
Theem 2 tau ua tiav xyoo dhau los thiab tau pib ua raws li lub tuam txhab thawj qhov kev xyaum xyaum ua haujlwm ntawm Santana thaum xyoo 2018 thiab 2019. Cov txiaj ntsig suav nrog kev sib tshuam ntawm 202 meters ntawm 0.51 g / t kub (los ntawm qhov chaw) xaus rau hauv mineralization hauv qhov S20-141.
Lub tuam txhab tseem tau ua tiav cov phiaj xwm thawj zaug rau Theem 3 qhov kev xyaum xyaum ua haujlwm uas yuav pib sai sai tom qab rov pib ua haujlwm mining hauv Mexico.
Minera npaj yuav ntxiv 20-25 qhov ntawm Nicho tag nrho kwv yees li 4000m nrog rau lub tuam txhab thawj qhov tho qhov ntawm Zata thiab Gold Ridge lub hom phiaj.
"Tam sim no peb tau txuas ntxiv rau sab nraud ntawm thaj chaw mineralized los ntawm yuav luag 150m los ntawm qhov tau txheeb xyuas yav dhau los thiab mus rau tag nrho cov ntsug qhov tob tshaj 200m. Cov mineralization zoo li tseem qhib nyob rau hauv ntau cov lus qhia nrog rau qhov tob, "said CEO Darren Koningen hauv xov xwm tshaj tawm.
"Peb kuj zoo siab los pib qhov kev sim xyaum ntawm ntau lub hom phiaj tshiab uas tau txheeb pom nyob rau hauv thaj tsam ntawm Santana txoj haujlwm nyob rau 18 lub hlis dhau los. Thaum lub sijhawm ntawd, peb pab pawg geological tau muab tso ua ke kom nkag siab ntau dua thiab txaus siab rau cov xwm txheej loj ntawm cov pob zeb hauv av ua lub luag haujlwm rau kev hloov pauv ntawm pawg ntawm cov kav dej kub-braccia. "
Ib tag hmo Wednesday, Minera cov Tshuag tau nce 5.6% ntawm TSXV. Lub tuam txhab muaj C $ 191 lab kev lag luam peev.
Pob Zeb Zeb Liner Khoom Xaiv
Cov khoom sib txawv crushed, txawv kev ua haujlwm xav tau cov ntaub ntawv sib txawv kom haum. Tsis tas li ntawd, cov ntxhib sib tsoo compartment thiab nplua sib tsoo compartment xav tau cov ntaub ntawv sib txawv.
H&G Machinery muab cov khoom hauv qab no los nrum koj lub pob zeb liner:
Manganese hlau
Cov ntsiab lus ntawm cov manganese steel pob zeb hauv ob sab phlu yog feem ntau 11-14%, thiab cov ntsiab lus carbon feem ntau yog 0.90-1.50%, feem ntau yog siab dua 1.0%. Ntawm qhov cuam tshuam qis, qhov hardness tuaj yeem ncav cuag HB300-400. Thaum muaj kev cuam tshuam loj, lub hardness tuaj yeem ncav cuag HB500-800. Nyob ntawm qhov cuam tshuam, qhov tob ntawm txheej txheej hardened tuaj yeem ncav cuag 10-20mm. Lub hardened txheej nrog siab hardness tuaj yeem tiv thaiv kev cuam tshuam thiab txo qis hnav. High manganese steel muaj kev ua tau zoo los tiv thaiv kev hnav zoo nyob rau hauv cov xwm txheej ntawm kev cuam tshuam zoo abrasive hnav, yog li nws feem ntau siv rau hauv qhov hnav-tiv taus ntawm cov mining, cov khoom siv, thermal zog, thiab lwm yam khoom siv kho tshuab. Nyob rau hauv cov xwm txheej uas tsis tshua muaj kev cuam tshuam, siab manganese hlau tsis tuaj yeem ua rau cov yam ntxwv ntawm cov khoom siv vim tias kev ua haujlwm hardening tsis pom tseeb.

Chrome Alloy hlau
Chromium alloy cam khwb cia hlau muab faib ua high chromium alloy cam khwb cia hlau (chromium ntsiab lus 8-26% carbon ntsiab lus 2.0-3.6%), nruab nrab chromium alloy cam khwb cia hlau (chromium ntsiab lus 4-6%, carbon ntsiab lus 2.0-3.2%), tsawg chromium Peb hom alloy cam khwb cia hlau (chromium ntsiab lus 1-3%, cov ntsiab lus carbon 2.1-3.6%). Nws qhov zoo tshaj plaws feature yog hais tias lub microhardness ntawm M7C3 eutectic carbide yog HV1300-1800, uas yog faib nyob rau hauv daim ntawv ntawm ib tug tawg network thiab cais nyob rau hauv lub martensite (lub hardest qauv nyob rau hauv cov hlau matrix) matrix, txo cov cleavage nyhuv ntawm matrix. Yog li ntawd, high-chromium alloy liner muaj lub zog siab, pob zeb toughness, thiab siab hnav tsis kam, thiab nws qhov kev ua tau zoo sawv cev rau qib siab tshaj plaws ntawm cov khoom siv hlau tam sim no.
