Wehewehe aukume whakarara teitei mowhiti papatahi
Tonokaupapa：
He whānuitia te whakamahinga o te wehewehe aukume porowhita papatahi ki te hematite mākū, te limonite, te siderite, te chromite, te ilmenite, te wolframite, te tantalum me te niobium ore me ētahi atu kohuke aukume ngoikore, me ngā kohuke kore-whakarewa, pērā i te quartz, te feldspar, hei tango i te rino poke me te purenga.
Ngā Āhuatanga Hangarau:
1. Ko tēnei raupapa hua he hanganga matatau, he mahi pono, he ngāwari te whakahaere me te tiaki, he roa te wā mahi,te pānga wehewehe paingā āhuatanga.
2. He whānui tōna urutau ki te rerekētanga o te rahi matūriki whāngai, te kukū me te māka, ā, kua tutuki te whāinga pai o te ōwehenga painga nui me te whakaora teitei.
