Emkhakheni wezimayini, imikhiqizo ye-Arex inezinhlobo eziningi zezicelo, ngenxa yezinzuzo zokumelana nokuguguleka nokugqwala, sikhiqiza inani elikhulu lemikhiqizo yerabha neyepulasitiki esetshenziswa emishinini yokucubungula amaminerali. Ngokusebenzisa izakhiwo zezinto ezingagugi nezimelana nokugqwala, njengerabha ne-polyurethane, imishini yezimayini nemishini ivikelwe ngokuphelele, futhi umonakalo ebusweni noma ngaphakathi kwemishini obangelwa ezinye izici, njenge-ore, uyancishiswa, ngaleyo ndlela kwandisa impilo yesevisi yemishini, kunciphisa ukuvama kokushintsha imishini nezesekeli. Imikhiqizo ye-Arex isetshenziswa kakhulu ezinhlelweni zezimayini nokuchoboza, izinhlelo zokuhlola i-ore, izinhlelo zokugaya nokuchoboza, izinhlelo zokuxhuma amapayipi, izinhlelo zokulethwa kwamatshe, njll. Imikhiqizo yerabha ne-polyurethane ingenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende noma izici ezithile zemishini, izici zezinto zingalungiswa ngokuya ngohlobo lwe-ore kanye nendawo yokusebenza ethile, konke okugxile ekukhuliseni ukusetshenziswa kwemishini nezesekeli ngempumelelo futhi kunciphise ubukhali bomsebenzi. Indawo yokusebenza ezimayini ivame ukuba nzima, futhi izindleko zokusetshenziswa kokusebenza kwemishini yezimayini zinkulu kakhulu. Ngokwezici zemishini ehlukene yokumba, i-Arex iklame imikhiqizo yerabha neyepulasitiki ehambisanayo, futhi ngalesi sisekelo ukuthuthukisa imikhiqizo yemishini, ukuqondisa iNkampani Yezimayini ukuthi iqedele ukufaka esikhundleni izingxenye zemishini. Njengomhlinzeki wesikhathi eside kulo mkhakha, i-Arex inesipiliyoni sobuchwepheshe be-patent kanye nokuthuthukiswa kwemishini eminingana, isevisi egcwele ezidingweni ezahlukahlukene zamakhasimende. Izinsizakalo ezisezingeni eliphezulu kanye nemikhiqizo engabizi kakhulu nayo iye yaqashelwa kabanzi ngamakhasimende omhlaba wonke. I-Arex inamathela esimisweni sekhwalithi kuqala, idumela kuqala, ikhiqiza imikhiqizo engcono kakhulu kumakhasimende, ilethe isivikelo sezintshisekelo zamakhasimende.
