Kei te whakakapi haere te arai rapa i te arai maitai konupora. Ka taea e ia te tu atu i te pānga kaha o te ātete. Ko te hua o ō ara hurihanga he mea tino whakawhirinaki ki te arai rapa o tō mira. Mā te whiriwhiri tika i te kaiwhakarato arai rapa ka tino whakarite kia oma tō tukanga hurihanga i te kaha me te wātea nui.
He pai ngā arai rapa mō te huri mākū, kaua e neke ake te pāmahana i te 80 nekehanga o te mahi noa, engari mō te huri maroke pāmahana teitei, te ātete waikawa kaha me te kawakore, te ātete hinu me ētahi atu taiao motuhake, me whakamārama i mua i te hoahoa motuhake me te hanga ritenga. Hei tāpiri, me waiho te tukanga rokiroki ki roto i te whare tiaki tika, kia kore ai e pāngia e te pāmahana tiketike me te ua ngā arai rapa.

E ai ki te kaupapa, ka wehea ngā arai rapa e whakamahia ana ki: AG, SAG, pōro, pebble, rod & batch mills, FGD, SMD me ngā mira tonu.
E ai ki te āhua, ka wehea ki te momo waipuke, te momo whatunga me te momo ipu maha, ka taea te whakatutuki i ngā whakaritenga o te huri taratara kotahi-wāhanga me te huri pai e rua-wāhanga.
Ka taea e mātou te whakarite i ngā momo rapa kounga teitei, ātete-mau hoki, kia rite ki ngā hiahia o ia kiritaki.
