Isihlabathi esinombala wemvelo sitholakala ngqo eMhlabeni. Sivela emadwaleni namaminerali aqukethe imibala yemvelo. I-iron oxide ingenye yezinto ezivame kakhulu zokufaka imibala zemvelo, ezibangela imibala ebomvu, e-orenji, nensundu ebonakala ezihlabathini eziningi ezinemibala yemvelo. Isibonelo, imibala ebomvu - ensundu yesihlabathi esithile sasehlane iwumphumela wokuqukethwe kwe-iron oxide. I-Manganese ingaletha imibala emnyama noma ensomi, kuyilapho izakhi zethusi zingase zibe nomthelela emibala eluhlaza neluhlaza okwesibhakabhaka. Ukukhishwa kwesihlabathi esinombala wemvelo kuqala ngemisebenzi yokumba emayini noma emifuleni lapho kutholakala khona lawa ma-diphozithi anombala. Uma sekumbiwe, izinto zokusetshenziswa kulandela uchungechunge lwezinyathelo zokucubungula. Ukuchoboza kuphula amatshe amakhulu abe yizicucu ezincane, kulandelwe ukuhlungwa ukuze kuhlukaniswe isihlabathi sibe osayizi abahlukene bokusanhlamvu. Kube sekuwashwa ukuze kususwe ukungcola okufana nobumba, uthuli, nezinye izinhlayiya ezingafuneki, kuqinisekiswe ukuthi isihlabathi sinezinga eliphezulu lokuhlanzeka kanye nobukhulu bombala obufunwayo.

Isihlabathi esinombala wokwenziwa, ngokuphambene nalokho, senziwa ngezinqubo ezenziwe ngabantu. Ngokuvamile, into eyisisekelo, ngokuvamile isihlabathi se-quartz ngenxa yobuningi baso, ubulukhuni, nombala ongathathi hlangothi, isebenza njengesisekelo. Amasu okufaka umbala athuthukisiwe asetshenziswa ukumboza noma ukudaya izinhlayiya zesihlabathi se-quartz. Abakhiqizi basebenzisa ama-pigment asezingeni eliphezulu kanye nama-bonding agents anembile ukuqinisekisa ukuthi umbala unamathela ngokuqinile ezinhlayiyeni zesihlabathi. Izindlela ezikhethekile zokumboza zingakha ungqimba lombala olufanayo noluhlala isikhathi eside, okuvumela ububanzi obukhulu bemibala okungase kube nzima ukuyithola ngokwemvelo. Ngokulawula ngokucophelela inqubo yokukhiqiza, isihlabathi esinombala wokwenziwa singafinyelela ikhwalithi yombala ehambisanayo kanye nokusatshalaliswa kosayizi wezinhlayiya, kuhlangatshezwane nezidingo eziqinile zezimboni ezahlukene.
