Izintengo ze-tungsten yamaShayina zigcine uzinzile njengoba ukukhathazeka kwesitoko se-Fanya kwaqhubeka nokuba nesisindo emakethe. Izimboni ezincibilikisayo zahlala zinezinga eliphansi lokusebenza ezithintwa ukuhlolwa kokuvikelwa kwemvelo futhi zisekelwa ukuncishiswa kwemikhiqizo yezimboni ukuze kuzinzise amanani. Manje yonke imakethe isathule ekuhwebeni.

Emakethe ye-tungsten concentrate, intengo yomkhiqizo edingwa abathengi yayiseduze nezindleko zokukhiqiza, okunciphisa inzuzo yamabhizinisi ezimayini kakhulu. Ngaphezu kwalokho, ukuhlolwa kwemvelo, izimvula ezinamandla kanye nezinga lokushisa eliphezulu kwenza ukukhiqiza kube nzima. Ngakho-ke, abathengisi babengazimisele ukuthengisa imikhiqizo ngokucabangela ukunikezwa okuqinile. Kodwa isidingo esibuthakathaka kanye nokushoda kwemali nakho kwacindezela imakethe.

Emakethe ye-ammonium paratungstate (APT), bekunzima ukuthenga izinto zokusetshenziswa zenani eliphansi nama-oda asuka ezansi nomfula awazange anyuke. Ngokunikezwa lokho, izimboni zokuncibilikisa azizange zisebenze ekukhiqizeni. Ngomthelela wokukhathazeka kwesitoko se-Fanya, abadayisi abaningi bagcina imizwa yokuqapha.

Abakhiqizi be-Tungsten powder babengenalo ithemba ngombono wokunikezwa kokuncintisana okuvela kubahlinzeki futhi bafuna amanani aphansi abahwebi. Intengo ye-tungsten powder ayizange ishintshe njengoba umsebenzi wamabala uthuthuka kancane ngesonto eledlule futhi ibhizinisi laphetha phakathi kwebanga. Isidingo esilokhu siba buthaka singase sibe nesisindo kumanani.
