Raws li cov qib ore poob qis ntawm South-American tooj liab-kub mines, ntau cov ore yuav tsum tau ua tiav, uas ua rau muaj kev thauj khoom hnyav dua rau ntawm lub puab tsaig crushers. Cov nqi hnav ntawm cov phaj puab tsaig txheem ib txwm muaj tau nce ntxiv 30-40%.
Cov mines tab tom txais yuav cov kev hloov kho tshiab hauv qab no:
- Txhim kho mus rau qib siab dua Mn22Cr2 high-manganese hlau;
- Siv cov phaj titanium-carbide-ntxig rau lub puab tsaig kom ntev dua 2-4 npaug;
- Tsim cov qauv hniav raws li cov yam ntxwv ntawm cov hlau;
- Txais yuav laser scanning rau kev saib xyuas kev hnav, hloov cov khoom raws li qhov xwm txheej hnav tiag tiag es tsis txhob siv lub sijhawm teem tseg.
