Ngaphambili, yonke intlabathi kunye namatye asetyenziswa ekwakhiweni kwezakhiwo zembiwa ukusuka kwindalo. Ngoku, ngenxa yomonakalo wemigodi engalawulekiyo kwindalo yendalo, emva kohlaziyo lomthetho wokusingqongileyo kwendalo, ukumbiwa kwesanti kunye namatye kulinganiselwe, kwaye ukusetyenziswa kwesanti ehlaziyiweyo kunye nelitye kuye kwaba yinto eshushu yokukhathazeka ngokubanzi. Phakathi kwazo, kunamandla kangakanani ukusetyenziswa komgca omkhulu wokuvelisa umatshini wezitena kwisanti ehlaziyiweyo kunye nelitye?

Njengoko sonke sisazi, ngokusetyenziswa okulinganiselweyo kwesanti namatye, amashishini amaninzi ajikela ekusetyenzisweni ngokutsha kwenkunkuma eqinileyo. Ngokutyumza imithombo yenkunkuma eqinileyo njengenkunkuma yokwakha, intsalela yenkunkuma yemizi-mveliso, intsalela yeentsalela zezimbiwa, njl.njl., banokuvelisa isanti ehlaziyiweyo esemgangathweni kunye nelitye ukuze bathathe indawo yesanti yendalo namatye. Okwangoku, isanti esetyenzisiweyo iye yaba yeyona mveliso yeminerali inkulu kunye nezixhobo zokwakha ezisisiseko kwindalo, kwaye i-China iye yaba yeyona ntengiso inkulu yehlabathi yesanti esetyenzisiweyo. Ukusetyenziswa ngonyaka kwesanti yenkunkuma eqinileyo malunga neetoni ezingama-20 eebhiliyoni, ezithatha malunga nesiqingatha sehlabathi liphela. Kwaye umatshini wezitena zemveli kunye nomgca omkhulu wokuvelisa umatshini wezitena weemveliso zezitena, izinto zayo zokuvelisa zithatha inxalenye enkulu yazo.

Umyinge wenkunkuma eqinileyo kwisitena esenziwe ngumatshini oqhelekileyo umalunga nama-20%, kwaye izinga lokusetyenziswa kwenkunkuma eqinileyo alikho phezulu, kodwa lingcono kunezininzi. Ngokusebenzisa iteknoloji entsha kunye nengqiqo, umlinganiselo wesanti yenkunkuma eqinileyo kunye nelitye kumgca wokuvelisa umatshini wezitena ezinkulu ungaphezulu ngokuphindwe kabini kunezitena eziqhelekileyo ezenziwe ngomatshini, oyimpumelelo kwiteknoloji yokwenza izitena kunye neteknoloji ehamba phambili.

Ukwakhiwa kwempucuko ye-ikholoji luphuhliso lwexesha elide kunye noluhambelanayo lwelizwe lethu. Ke ngoko, asinakuxhaphaza kwaye sisebenzise izixhobo zendalo ngobumfama, nto leyo engunobangela wokuzalwa kwelitye lentlabathi elinokuhlaziywa. Ngezinto ezibambeleyo, izinga losetyenziso liya kuphuculwa ngokwemvelo. Ngokusebenzisa uphando olunzulu kwii-aggregates ezahlukeneyo zenkunkuma eqinileyo kunye nohlalutyo lweendlela zemolekyuli, abaphandi bezenzululwazi be-Honcha baye baphumelela ngempumelelo kwiingxaki zobugcisa kwishishini emva kweminyaka eliqela, badala i-high-pressure vibration kunye ne-extrusion technology, kwaye bayilungiselele kwisixhobo sokuvelisa umatshini wezitena omkhulu, kunye nokwenza izitena.
