Endeavor Silver inovhurazve Mexico migodhi
Canada's Endeavor Silver (TSX: EDR) (NYSE: EXK) yatangazve kushanda pamigodhi yayo mitatu yepasi pevhu yegoridhe-goridhe muMexico, zvichitevera mvumo kubva kuvakuru vehutano hwenyika.
Iyo Vancouver-yakavakirwa sirivheri inogadzira yakacherekedza migodhi yayo uye zvidyarwa zvaive zvichikwira kumusoro kuti zviitwe zvakajairwa. Yakatiwo vashandi vekuongorora vachatangazve kugadzira mepu, sampling uye zvirongwa zvekuchera muna Chikumi.
Chiziviso ichi chinotevera nhau kubva kune mumwe mugodhi wekuCanada Fortuna Silver Mines (NYSE: FSM) (TSX: FVI) kuti mugodhi wayo weSan José, mudunhu reMexico rekumaodzanyemba kweOaxaca, wadzoka pakazara.
Pakutanga mwedzi uno, Endeavor Silver yakatumira kurasikirwa muchikamu chekutanga, nemari yakadzikira nekuda kwekumbomira kushanda pachirongwa cheEl Cubo. Mhedzisiro yakakanganiswawo nezvakabuda zvakapinda muzvinyorwa pane kutengeswa nekukurumidza.
Endeavour ine migodhi mitatu yegoridhe-goridhe muMexico: mugodhi weGuanaceví mudunhu reDurango, mugodhi weBolañitos muGuanajuato uye mugodhi weEl Compás mudunhu reZacatecas.
Mamwe makambani akati wandei, anosanganisira Newmont Mining (NYSE: NEM), Pan American Silver (TSX: PAAS), Alamos Gold (TSX, NYSE: AGI), Argonaut Gold (TSX: AR), Sierra Metals (TSX: SMT), Excellon Resources. (TSX: EXN) uye Torex Goridhe (TSX: TXG), vatangazve migodhi yavo yeMexico kana kuronga kuzviita mumazuva anouya.
Simbi yakaoma zvikuru
Sirivha ndiyo yave chinhu chakanyanya kurohwa nekuvharwa kwemigodhi yakarairwa nehurumende kumisa kupararira kwegoronavirus.
Mexico, mugadziri wepamusoro wesimbi pasi rose, akatarisana muna 2020 imwe yekudzika kwakadzika munhoroondo yayo sezvo hupfumi hwatove husina kusimba haugone kubata nekukanganisa kwedenda re coronavirus.
Hupfumi hwenyika huri kufanotaura kuti huchaita chibvumirano che6.7% gore rino, zvakadzika kupfuura panguva yeTequila Dambudziko repakati pemakore ekuma1990, ongororo yazvino yeCitibanamex inoongorora inoratidza.
Mexico ndiyo inokonzeresa kugadzirwa kwesirivheri pasi rose, inosvika makumi maviri nenhatu kubva muzana, ichiburitsa maonzi anopfuura mamirioni mazana maviri gore rapfuura, kubva pamamiriyoni mazana maviri nemakumi mapfumbamwe nematanhatu muna 2018.
Iyo ine zvakare migodhi mikuru yemhangura neyezingi, inoshandiswa neGrupo Mexico neSouthern Copper, uye inogadzira huwandu hwakakosha hwegoridhe, zvichiita kuti chikamu chemigodhi chitore chikamu che4% chechigadzirwa chenyika.
Ball Mill Liner Material Sarudzo
Yakasiyana yakapwanyika zvinhu, akasiyana ekushanda mamiriro anoda akasiyana zvinhu liner kuti aenderane. Zvakare, iyo yakakasharara yekukuya compartment uye yakanaka yekukuya compartment inoda akasiyana matinji.
H&G Michina inopa zvinotevera zvinhu kukanda yako bhora chigayo liner:
Manganese Steel
Iyo manganese yemukati meyakakwira manganese simbi bhora chigayo lining plate inowanzo 11-14%, uye iyo kabhoni yemukati inowanzo 0.90-1.50%, mazhinji ayo ari pamusoro pe1. Pamitoro yakaderera, kuoma kunogona kusvika HB300-400. Pakukwirisa mitoro, kuoma kunogona kusvika HB500-800. Zvichienderana nekutakura mutoro, kudzika kweiyo yakaomeswa layer inogona kusvika 10-20mm. Iyo yakaomeswa layer ine kuomarara kwakanyanya inogona kuramba kukanganisa uye kuderedza abrasive kupfeka. Yakakwira manganese simbi ine yakanakisa anti-kupfeka mashandiro pasi pemamiriro eiyo yakasimba kukanganisa abrasive kupfeka, saka inowanzoshandiswa munzvimbo dzisingapfeki dzemigodhi, zvekuvaka, simba rekupisa, uye zvimwe zvemichina. Pasi pemamiriro ekuderera kwemamiriro ezvinhu, yakakwira manganese simbi haigone kuita hunhu hwechigadzirwa nekuti basa rekuomesa mhedzisiro haisi pachena.
