Mai i te whakatinanatanga o te rauna hou o ngā putanga hou i roto i te rautaki tūhuratanga kohuke, kua whakahaerehia e te China Geological Survey o te Manatū Rauemi Taiao, me te Kāwanatanga o te Iwi o te Porowini o Hubei, he rangahau whānui me te whakawhanake i te hangarau whakamahinga whānui o te putunga whenua onge niobium nui rawa o Miaoya i te rohe o Zhushan Zhuxi i te Porowini o Hubei ki te raki-mā-uru. Kua hinga te hangarau matua mō te whakamahinga whai hua o ngā rauemi niobium, ā, ka whakahohehia te 929000 tana o ngā rauemi niobium hei whakatutuki i te whakamahinga ōhanga o te putunga whenua onge niobium nui rawa o Miaoya.
Mā te whanaketanga me te whakatairanga i ngā hangarau matua mō te whakamahinga whānui o ngā rauemi niobium i te raki-mā-uru o Hubei ka whakaratohia he ara hangarau e taea ai te whakamahi i ngā rauemi niobium iti te kounga me ngā rauemi uaua ki te whakamahi o Haina. He mea nui tēnei mō te whai rawa o Haina i ngā rauemi niobium me te whakapai ake i ōna āheinga haumarutanga.
He āhuatanga ātete waikura me te ātete pāmahana teitei te niobium, ā, he konganuku matua nui i roto i ngā mara o te rererangi, te tiaki whenua, te ahumahi hōia, me te pūngao karihi. He rauemi rautaki nui. Kua kitea e Haina te 4.7 miriona tana o ngā rauemi, ko te tuarua o te ao, e kohikohi ana i ngā rohe pēnei i a Baiyun Obo i roto o Mongolia, Liangzhu i Hubei, Yichun i Jiangxi, Baicheng i Xinjiang, me Huayangchuan i Shaanxi. Ki te whakatauritea ki ngā whenua ke, he uaua ngā āhuatanga o ngā rauemi niobium i Haina, he iti ngā kounga, ā, he uaua ki te whakamahi.
Ko te hītori tūhuratanga o te maina whenua onge niobium o Miaoya ka taea te whai i ngā tau 1960, engari nā ngā herenga hangarau, he uaua tonu te whakatutuki i te whanaketanga me te whakamahinga rauemi. Mā te whakamahinga whānui o ngā putanga hangarau, kua whakawhanakehia e ngā kairangahau whenua Hainamana he hangarau wehewehe whenua onge niobium, ā, kua tutuki i a rātou he putanga nui i roto i ngā hangarau matua mō te whakamahinga whai hua o ngā rauemi niobium. Kua piki ake te taumata o te niobium concentrate mai i te 5% ki te 8% i roto i ngā tukanga tuku iho ki te 17%, ā, kua piki ake te tere whakaora mai i te 20% ki te 50%. I taua wā anō, kua tutuki te whakamahinga whānui o ngā rauemi whenua onge, te rino, te whanariki me ētahi atu rauemi, ā, kua tino whakarite i te haumarutanga o te tuku rauemi niobium ki Haina.
