Mitengo ya tungsten yaku China idakhalabe yokhazikika kumayambiriro kwa sabata. Mlandu wachiwiri wa mlandu wa Fanya unathetsedwa Lachisanu lapitali pa July 26, 2019. Makampaniwa anali ndi nkhawa ndi matani 431.95 a tungsten ndi matani 29,651 a ammonium paratungstate(APT). Kotero ndondomeko yamakono yamakono ikanakhalabe yosasinthika pakanthawi kochepa.

Kumbali imodzi, mitengo yotsika pamsika komanso mtengo wokwera wachitetezo cha chilengedwe zikufinya phindu lamakampani, ndipo mafakitale ena amakumana ndi zovuta zakusintha kwamitengo. Ogulitsa safuna kugulitsa. Kuphatikiza apo, kuwunika kwachilengedwe, mvula yamkuntho komanso kuchepa kwamakampani kumachepetsanso kuchuluka kwazinthu zotsika mtengo. Kumbali inayi, ogula sakugwiranso ntchito pakubwezeretsanso kumbali yofooka yofunikira ndikudandaula ndi masheya a Fanya. Kusakhazikika kwachuma ndikovutanso kukulitsa chidaliro chamsika. Chifukwa chake, msika ukuyembekezeka kugwidwa mumlengalenga.
