Andean Precious Metals Corporation (APM) tau lees paub qhov pib ntawm kev nthuav dav kev tshawb fawb ntawm nws San Bartolome Mine, ib kauj ruam tseem ceeb hauv nws txoj kev npaj tswv yim los txuas ntxiv lub neej ntawm cov mine, uas tej zaum yuav suav nrog kev tsim cov tin.
Nyob hauv Potosi, Bolivia, SAN Bartolome Project yog tus tswv thiab ua haujlwm los ntawm APM. Qhov project no feem ntau yog ib lub mine nyiaj uas tau tsim qhov nruab nrab ntawm ntau tshaj 5 lab ooj nyiaj hauv ib xyoos txij li xyoo 2008.
Txoj kev tshawb fawb txog $ 2 lab yuav muab faib ua peb ntu: kho tshiab cov peev txheej kev kwv yees, kev tshawb fawb txog kev tshawb fawb thiab kev ntsuam xyuas tailings.
Thaum lub sijhawm 13 xyoos ntawm kev ua haujlwm, cov ntaub ntawv zoo (tsawg dua 2.5 hli) tau raug tshuaj xyuas ua ntej kev ua haujlwm thiab tom qab ntawd muab khaws cia rau ntawm lub mine's Fine-grained material Disposal Facility (FDF). FDF tam sim no muaj txog 10 lab tons ntawm cov khoom no. Tsis tsuas yog cov khoom nplua-grained muaj qee cov nyiaj, tab sis APM ntseeg tias nws yog qhov muaj peev xwm ntawm cov tin, vim nws tau mined los ntawm CerroRico deposit, uas paub tias muaj qib siab tin.
Andean tau ua tiav tag nrho cov drilling xav tau rau FDF cov peev txheej kev kwv yees thiab npaj yuav tshaj tawm cov lus tshaj tawm thaum Lub Ib Hlis 2022.
Txoj kev tshawb nrhiav scope yuav soj ntsuam cov txheej txheem tin rau cov ntaub ntawv khaws cia. Txawm hais tias yuav hloov mus rau cov nroj tsuag tam sim no nrog lub ntiajteb txawj nqus los yog mus rau ib tsob ntoo tshiab nyob ib leeg nyob ntawm qhov zoo tshaj plaws tin rov qab. Kev ntsuam xyuas ntawm lub cev ntawm cov ntaub ntawv hauv Tshuag rau kev ntsuam xyuas tseem tsis tu ncua thiab yuav raug tso tawm hauv thawj peb lub hlis twg ntawm 2022.
Lwm lub sijhawm rau kev tsim cov tin yog Lub Tshuab ziab khaub ncaws Tailings Facility (DSF), uas muaj 18 lab tons ntawm cov khoom. Cov tailings yav tas los tau ua tiav rau nyiaj, tab sis tsis yog rau tin. Drilling tau pib ntawm cov tailings los ntsuam xyuas tus nqi thiab qib ntawm cov tin, uas yuav tsis suav nrog hauv kev kwv yees cov peev txheej tshiab. APM cia siab tias yuav tshaj tawm cov txiaj ntsig drilling hauv thawj peb lub hlis twg ntawm 2022.
Peb qhov kev pom: APM's SAN Bartolome project sawv cev rau lub sijhawm ze-kev lag luam tin tsim, muab qhov qis capex thiab kev tsim kho tsis zoo ntawm cov phiaj xwm kho dua tshiab. Hauv tsab ntawv tshaj tawm ua lag luam yav dhau los, cov tailings ib leeg tau kwv yees li 10 lab tons ntawm ore, muaj 0.25 feem pua tin (25,{5}} tons tin kub). Vim tias cov khoom zoo-grained tau raug crushed, APM ntseeg hais tias ob qho tib si stocks (FDF thiab DSF) tuaj yeem raug mined siv cov nqi qis hydraulic mining.
