Nevada Copper inogadzirira kutangazve kugadzira muQ3
Nevada Copper (TSX: NCU) iri kufambira mberi yakananga kunotangazve kugadzirwa kwemukati muQ3 2020, muridzi wePumpkin Hollow copper project yakaziviswa mune imwe update Chipiri.
Kugadzirwa pamugodhi wepasi pevhu kwakamiswa kwechinguva kutanga kwaKubvumbi nekuda kwezvirambidzo zvekufamba uye zvebasa zvakatemerwa nenyika yeNevada kumisa kupararira kweCovid-19.
Sechikamu chegadziriro dzayo dzekutanga patsva uye hurongwa hwekusimudzira mugodhi, Nevada Copper yapedza kusimudzira kwakatwasuka kweiyo shaft huru kusvika pakadzika kwekupedzisira kwemamita 2,131, uye iri kuenderera mberi nekusimudzira lateral kuwedzera ore murwi pamberi pekutanga kwechirimwa. Phased remobilization yevashandi vezvirimwa zvatangawo, kambani yakati.
Zvichakadaro, Nevada Copper ichangobva kubaya imwe nzvimbo yepasuru inovhara angangoita 680 maeka akatarisana nePumpkin Hollow chivakwa uye pamwe nekumabvazuva kwemuganhu wenzvimbo yeTedeboy.
Ongororo yezvakaitika kare aero-magnetic ongororo data yakaratidza hurefu hwemagineti hunofambirana nekuzivikanwa kwechicherwa chemhangura isinganzwisisike pamusoro nemasampuli ekubata achidzosera mamakisi emhangura, zvichisimbisa tarisiro yenzvimbo ichangobva kuwanikwa iyi.
Shareholder Pala Investments yakapa chisungo chemubhadharo kukambani nechikwereti chenguva pfupi chemadhora 5.5 miriyoni, ichipa mari kana ichidiwa mukusimudzira uye kutangazve kushanda paPumpkin Hollow.
Migove yeNevada Copper yakavhura chikamu chegumi muzana chepamusoro paTSX. Iyo Vancouver-yakavakirwa mhangura inogadzira ine musika capitalization yeC $ 155.7 miriyoni.
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.
