Ib tus neeg siv khoom hauv tebchaws Australia tsim Tunsgtenplant hauv Nyab Laj, thaum xub thawj cov kauv concentrator thiab tuav lub rooj yuav los ntawm Amefica.
tom qab lub worskite enginner nrhiav peb lub tuam txhab, thiab muab qhov xav tau kom meej, peb raws li lawv qhov yuav tsum tau ua rau txheej txheem. lub lawj txheej txheem kom beRhombus cov duab kom haum lawv tshwj xeeb Tunsgtenminerals.so qhov chaw ua haujlwm tag nrho cov kauv concentrators thiab co lub rooj hloov rau peb cov khoom lag luam.
Peb tsim kev koom tes txij li xyoo 2008, nws nyob ib puag ncig txhua 3 xyoos hloov cov khoom lag luam tshiab txhua lub hlis xa 18sets co lub rooj.UseOpen sab saum toj txee rau thauj khoom.
Txhua lub tshuab tuaj yeem tsim kho raws li xav tau, tsuas yog muab qhov yuav tsum tau ua yog ok.
tuav cov lus raws li lub ntiajteb txawj nqus cais lub tshuab kawg kauj ruam, rov ua piv tau zoo tshaj, tab sis lub peev xwm muaj tsawg.
nws' zoo rau kev sib cais tag nrho cov ntxhia hnyav, xws li TunsgtenKub, Nyiaj, Tin, Columbium, Tantalum, Titanium, Barium, Tungsten, Hlau, Chrome, Manganese, Zircon, Lead, Zinc, Mercury, Copper, Aluminium, thiab lwm yam qhov pub mis loj yog 2 hli.
