Ka whakahaere tika ēnei tawhā i te pai o te wehenga o te sylvite me ētahi atu kohuke utu nui mai i ngā poke, e pā ana ki te whakapai ake i te whai huatanga o te wehenga kohuke engari ki te parakore whakamutunga me te taumata o te kukū. He maha ngā wā ka puta he ngaronga o te whakaoranga, te pikinga o ngā paru, me te whakararuraru i te mahi nā te hē o ngā mātotoru, e whakaatu ana i te hiahia mō te ine tika i ia taahiraa o ngā tikanga tukatuka kohuke potash.
Ko te whanaungatanga tata i waenga i te mātotoru paru kua whakahaeretia me te tere whakaora kukū kua whakapaitia e whakaatuhia ana e ngā raraunga mara me ngā mahi pai o te umanga. Hei tauira, ko te pupuri i te mātotoru tino pai i roto i te ara iahiko whakapūmau ka whakarei ake i te whakaora whakapūmau i roto i te keri potash mā te whakanui ake i te pa o te mirumiru-matūriki me te whakaiti i te urunga o ngā kohuke gangue. Ko te hua o tēnei he auau whakaora KCl teitei tonu—he maha ngā wā 85–99% e ai ki ngā kaihanga matua. I roto i te whakatiotanga, ka taea e te whakahaere mātotoru te arotau i ngā taumata supersaturation, te whakaiti i te kai pūngao, me te whakarite i ngā whāinga parakore o te hua, he mea nui mō te tukatuka i raro iho, te hoko tika rānei. Ko ia wāhanga, mai i te huri ki te wehenga kaha i roto i te keri, ka whai hua mai i te whakahaere mātotoru—te whakaiti i te wā kore mahi taputapu, te whakarei ake i te tiaki wai, me te whakapai ake i te hua o te tipu whānui.
Ko te auahatanga tonu i roto i ngā tikanga ine mātotoru mō te paru i roto i te keri kei te whakakaha i te hiranga mahi puta noa i te umanga. Ko te nekehanga atu i ngā tātari taiwhanga ā-ringa, puhoi me ngā ine karihi ki ngā hangarau ultrasonic me Coriolis-wā-tūturu, kore-whakaekenga, ko te tikanga he tere ake te urupare a ngā kaiwhakahaere ki ngā huringa tukatuka, ka whakaiti i ngā mate tinana me ngā mate pūtea. Ko te whakaurunga ki ngā pūnaha whakahaere tukanga matatau ka whakamanahia ngā whakatikatika aunoa, ka whakaiti i te hapa tangata me te tautoko i ngā tikanga hanga potash haumaru, pumau. I te whakakaha haere o ngā ture me te whanaketanga o ngā hihiri mākete, ko ngā mahi pai inaianei e aro nui ana ki te aroturuki mātotoru e whakahaerehia ana e te pūoko, te whakangungu tonu o ngā kaimahi, me ngā whakahoutanga taputapu auau hei whakatutuki i te pikinga o te tono me te hekenga o ngā taumata o te konganuku. Mā te tango i ēnei mātāpono ka whakanui ake i te whai huatanga, ka whakanui ake i te whakaora kukū mā te whakamahi i ngā tikanga hei whakanui ake i te whakaora kukū i roto i te tukatuka kohuke, ā, ka tukuna tonutia ngā hua potash kounga teitei.
