1. Ngā rauemi mata rerekē: ko te rauemi mata o te kōrunuma parauri ko te bauxite, me te anthracite me te rino. Ko te rauemi mata o te kōrunuma mā ko te paura konumohe waikura.
2. Ngā āhuatanga rerekē: he tino parakore te kōrunuma parauri, he pai te whakatioata, he kaha te rere, he iti te tauwehenga whānui, he ātete ki te waikura. He tino parakore te kōrunuma mā, he pai te whakakoi i a ia anō, he ātete ki te waikura waikawa me te kawakore, he ātete ki te pāmahana teitei, ā, he pumau te mahi wera. Ki te whakataurite, he teitei ake te pakeke o te kōrunuma mā i te kōrunuma parauri.
3. Ngā kai rerekē: ahakoa kei roto i te kōrundum parauri me te mā te alumina, he nui te alumina i roto i te kōrundum mā,
4. Ngā tae rerekē: Nā te mea he nui ake te ihirangi alumina o te kōrunuma mā i te kōrunuma parauri, he mā te tae o te kōrunuma mā, ā, he parauri pango te kōrunuma parauri.
5. Te whakaputanga rerekē: ko te korundum mā he mea hanga ki te paura alumina (ko te rauemi mata kotahi ki te konumohe hiko), ko te korundum parauri he mea hanga ki te bauxite kua whakapūkaratia.
6. He kaha te kaha tapahi o te kōrunuma mā, e whakamahia ana hei tango i ngā pūwero whakarewa, ngā pūwero mua puranga, me ētahi atu. He mahi whakakanapa i te mata o ngā wāhanga, ko te kōrunuma parauri e whakamahia ana hei tango i ngā pūwero mata o ngā wāhanga taputapu.
7. Te whakamahinga o ngā mea rerekē: e whakamahia ana te kōrunuma mā e ētahi kaiwhakamahi matatau, nā te mea he kaha ake te tapahi, he tino pai te pānga oro, e whakamahia ana mō te maitai waro, te maitai koranu, te rino ngāwari, te parahi mārō me ētahi atu, ā, e whakamahia whānuitia ana te kōrunuma parauri i te mākete, engari he nui te horopeta o te mākete, e whakamahia ana mō te maitai ahi, te maitai tere-teitei, te maitai waro-teitei me ētahi atu.
He kaha te kaha tapahi o te kōrunuma mā, hei tango i ngā pūwero whakarewa, ngā pūwero o mua puranga, me ētahi atu. He mahi whakakanapa i te mata o ngā wāhanga, ko te kōrunuma parauri hei tango i ngā pūwero mata o te maitai kore waikura, te maitai waro, te koranu konumohe me ētahi atu wāhanga taputapu. Kāore te kōrunuma parauri e huri kia rite te matotoru me te kanapa ki te kōrunuma mā.
