Ukuqaqa ama-smartphones ukuze kutholwe ukuthi enziwe ngaziphi izakhi nokuthi kuyini ukulungiswa kwawo akuvamile kulezi zinsuku - imikhiqizo esanda kumenyezelwa noma emisha edayiswayo ivamise ukwenziwa yile nqubo. Kodwa-ke, inhloso yokuhlolwa kososayensi eNyuvesi yasePlymouth kwakungekhona ukukhomba ukuthi iyiphi i-chipset noma imojuli yekhamera efakwe kudivayisi yokuhlola. Futhi njengowokugcina, abakhethanga imodeli yakamuva ye-iPhone. Futhi konke ngoba ucwaningo lwaluklanyelwe ukusungula ukwakheka kwamakhemikhali kagesi wesimanje.
Ukuhlolwa kwaqala ngokuchotshozwa kwe-smartphone ku-blender, okwathi ngemva kwalokho izinhlayiya ezincane zahlanganiswa ne-agent enamandla oxidizing - i-sodium peroxide. Ukuhlaziywa kokwakheka kwamakhemikhali kwale ngxube kubonise ukuthi ifoni ehloliwe iqukethe ama-33 g ensimbi, 13 g we-silicon, 7 g we-chromium kanye nenani elincane lezinye izinto. Nokho, ososayensi baqaphela ukuthi ngaphezu kwabo, igajethi echotshoziwe iqukethe 900 mg we tungsten, 70 mg cobalt futhi molybdenum, 160 mg neodymium, 30 mg praseodymium, 90 mg isiliva kanye 36 mg yegolide.
Ukuze kukhishwe lezi zakhi ezingavamile, inqwaba yensimbi kufanele ikhishwe emathunjini omhlaba, okulimaza imvelo yeplanethi yethu, abacwaningi baphawula. Ngaphezu kwalokho, izinsimbi ezifana ne-tungsten ne-cobalt zivame ukuvela ezindaweni ezingqubuzanayo e-Afrika. Ukuze ukhiqize idivayisi eyodwa, kuyadingeka ukukhipha isilinganiso sika-10-15 kg we-ore, kuhlanganise no-7 kg wensimbi enegolide, i-1 kg yethusi, i-750 g ye-tungsten kanye ne-200 g ye-nickel. I-concentration ye-tungsten ku-smartphone iphakeme ngokuphindwe kashumi kunamatshe, futhi ukugxiliswa kwegolide kungase kube ngokuphindwe izikhathi eziyikhulu. Ngokusho kososayensi, ukuhlola kwabo kufakazele isidingo sokuphinda kugaywe kabusha kwama-electronics ekupheleni kwempilo.
