Imizwa emakethe ye-ammonium paratungstate (APT) ibe ngcono ngesonto eliphele ngoLwesine ngoSepthemba 12 njengoba kulindeleke ukuba kube yimpumelelo endalini yamasheya e-tungsten aphethwe yi-Fanya Metal Exchange engasekho futhi phakathi nokuqinisa ukunikezwa kwe-concentrates e-China.

Ukuhlinzekwa kwamanani entengo ye-tungsten yempahla eluhlaza kuqhubekile ukuhlala kuqinile ngaphansi kokuvikelwa kwemvelo kanye namabhizinisi ezimayini amisa ukukhiqizwa ukuze kulungiswe.Izintengo eziphansi zokuthengiselana eziqhubekayo kanye nezindleko eziphakeme zezimayini zikhuphule ukukhuphuka kwengqondo okuqinile kwabathengisi futhi ngaleyo ndlela amanani e-tungsten ore asekelwa.

Emakethe ye-APT, njengoba indali yezitoko ze-Fanya izophela maduze, imizwa yethemba isekele amanani e-APT.Kwakunzima ukuthenga izinsiza ngenkathi amanani ephansi kuno-198.6/mtu.Ukuthengiselana kwangempela nakho akuzange kuqedwe.Imakethe kulindeleke ukuthi ibanjwe endaweni yokulinda bese ubona ngaphambi kokuphela koMkhosi Wasekwindla.
