I-chrome ore iyimpahla ebalulekile esebenziselwa ezinhlelweni ezahlukene zomkhiqizi, ikakhulukazi ekukhiqizeni i-ferrochrome, ebalulekile ekwakheni insimbi engena-oda. Ikhwalithi ye-chrome ore ibhekwa ngezincazelo eziningana ezithinta ukufaneleka kwayo ekusetshenzisweni kwezomkhiqizo. Le ndatshana ihlola izincazelo ezibalulekile ezichaza i-chrome ore yekhwalithi ephezulu yokuthengisa kwezomkhiqizo.
Ukwakhiwa kwemakhemikhali kwe-chrome ore kuyisizathu esiyinhloko sokuhlola ikhwalithi yalo. I-chrome ore yekhwalithi ephezulu ivame containing:
– Ingxenye ebaluleke kakhulu, equkethe i-ore ephezulu enama-40% kuya kwama-52% Cr2O3.
– Ukuphuma kwe-silica okuphansi kuyathandwa, ngokuvamile okungaphansi kuka-5%.
– Kufanele kube phansi, imvamisa ngaphansi kwe-20%.
– Ngokuvamile, ngaphansi kuka-10% kuyamukeleka.
– Ngokuvamile, ngaphansi kwama-5% kuyingcwele.
Izimpawu zomzimba ze-chrome ore nazo zidlala indima ebalulekile ekutheni ziqinisekise kanjani izinga layo:
– Ukuhlinzeka ngesisindo esifanayo sokuhlukahluka kwezinsalela kubalulekile ukuze kwenziwe kahle. Usayizi ungashintshashintsha ukusuka kumafayili kuye kumajubane, nangezicelo ezithile zemboni.
– Ukuntuleka kokwaziswa kokuncibilikisa kubalulekile ukuvimbela izinkinga ngesikhathi sokuthuthwa kanye nokucubungula.
Ukuqonda izici ze-mineralogical ze-chrome ore kubalulekile ekuhloleni ikhwalithi yakhona:
– Ubukhulu bezinhlayiya ezinkulu bavame ukukhethwa njengoba zandisa ukusebenza kahle kwenqubo yokuchoboza.
– Ubukhona bezinsimbi ezingafuneki kufanele bube phansi ukuze kuncishiswe izindleko zokucubungula futhi kuthuthukiswe umkhiqizo.
I-chrome ore ethuthukile kufanele ihlangabezane nezindinganiso ezithile zezimboni nezitifiketi:
– Ukuhambisana nezindinganiso zamazwe omhlaba ezifana ne-ISO 6153 ye-chrome ore kubalulekile.
- Ukuhambisana nemithetho yomphakathi yokumba nokuthumela ngaphandle kubalulekile ukuze kube nokusebenza okuvumelekile nokuphephile.
Izici zezezimali ziphinde zibe nomthelela ekuchazeni ithuluzi le-chrome eliphakeme.
– Imbobo yekhwalithi ephezulu ivame ukuthola intengo ephezulu, kodwa ukuzinza kwentengo kubalulekile ezinkonzweni zesikhathi eside.
– Izingxoxo zokwaziswa ezithembekile ziqinisekisa ikhwalithi ehlelekile nokutholakala, okuyinto ebalulekile kubathengi bezimboni.
Ezindaweni zoshishino zanamuhla, ukubheka imvelo kanye nezinqubomgomo zokuziphatha kuyaqhubeka nokubaluleka kakhulu:
– I-chrome ore yekhwalithi ephezulu kufanele itholakale emisebenzini ebeka phambili ukumelana nezinguquko zemvelo nokunciphisa umthelela wemvelo.
– Ukuhambisana namazinga wokuziphatha kanye nemikhuba efanelekile yokusebenza kubalulekile ekuqoqweni okufanele.
I-chrome ore yekhwalithi ephezulu ichazwa ngokuhlanganiswa kokwakheka kwemichilo, izici zomzimba, izici ze-mineralogical, imigomo yezimboni, ukuqonda kwezomnotho, kanye nezici zemvelo nezokuziphatha. Ukuqonda lezi zinkcukacha kusiza abathengi nabakhiqizi ukuqinisekisa ukuthi i-chrome ore ihlangabezana nezidingo zokusebenza kwezobunjiniyela, ikakhulukazi ekukhiqizeni i-ferrochrome yokwenziwa kwensimbi engaqedwa. Ngokuvumelana nalezi zinkcukacha, ababambiqhaza bangakwazi ukuthuthukisa ukusetshenziswa kwe-chrome ore ezifundeni eziningi zezimboni, beqinisekisa ukusebenza kahle, ukumelana nezimo, nokwenza inzuzo.
