      Ukunyuka kwexabiso elinqabileyo lomhlaba wempahla

      Itshathi yamaxabiso ibonisa ukuba iindleko zempahla eluhlaza yeemarike zoMhlaba oNqabileyo zeNeodymium ziye zanda kakhulu kwiiveki ezimbalwa ezidlulileyo. Oku kwenza ukuba abanye abathengi babe nexhala malunga neendleko zeemveliso zabo kwaye babuze ukuba iyakuba yintoni imeko kwezi nyanga zilandelayo kwaye kufuneka basabele njani.
