Feme le Sehlopha

Hajoale, k'hamphani ea rona e na le basebetsi ba 158, ho kenyeletsoa basebetsi ba R&D ba 18 ba nako eohle le litsebi tse 3 tse phahameng tsa kahare, har'a bona, ho na le litsebi tse 5 tse nang le litlotla tse mahareng le tse phahameng. E thehile sehlopha sa lipatlisiso le nts'etsopele se nang le phihlelo e ngata ea theory le e sebetsang, e etelletsoeng ke litsebi tse ka sehloohong tsa malapeng le litsebi tsa metallurgical.

Ho fihlela joale, k'hamphani ea rona e thehile mela e 'meli ea tlhahiso ea phofo ea tšepe ea athomo ea metsi, mela e 'meli ea koporo ea phofo ea oxide le mohala o le mong oa tlhahiso ea cuprous oxide, o nang le matla a selemo le selemo a lithane tse 20,000. Ka nako e ts'oanang, k'hamphani ea rona e sebelisa theknoloji e tsoetseng pele ea lapeng ts'ebelisong e felletseng ea tharollo ea boto ea potoloho. Bokhoni ba selemo le selemo ba chloride ea koporo, cuprous chloride, carbonate ea mantlha ea koporo le lihlahisoa tse ling tse hlahisoang ka ho lahla ntle le kotsi ea koporo-e nang le tharollo ea etching e fihlile ho lithane tse 15,000, mme boleng ba tlhahiso ea selemo le selemo bo tla fihla ho li-yuan tse limilione tse likete.
