ʻO ka Technology Center o Jilin Yuantong Mineral Co., Ltd. i kēia manawa he 42 mau limahana, a he 18 mau loea ʻoihana e hana nei i ka hoʻomohala ʻana a me ka noiʻi ʻana o ka honua diatomaceous, a ʻoi aku ma mua o 20 mau pūʻulu o nā mea hoʻāʻo kūikawā diatomite ma ka home a ma waho. Aia nā mea ho'āʻo: Crystalline silicon content of diatomaceous earth products, chemical composition like SiO2, A12O3, Fe2O3, TiO2; ka hāʻawi ʻana i nā ʻāpana, keʻokeʻo, permeability, wet density, screening residue, lead, arsenic and other trace heavy metal elements e pono ai no ka palekana o ka meaʻai, soluble iron ions, soluble aluminum ions, PH value a me nā mea ʻē aʻe e pono e hoʻāʻo ʻia.
ʻO ke kikowaena i kēia manawa ʻo ia wale nō "ke kikowaena ʻenehana ʻoihana o Jilin Province" no nā ʻoihana mining diatomite a me nā ʻoihana hana ma Kina.
Ua alakaʻi ke kikowaena i ka hana ʻenehana me kekahi mau kulanui kaulana a me nā keʻena noiʻi ma Kina. Ua hoʻololi ʻia kekahi mau hanana noiʻi ʻepekema i waiwai nui no ka ʻoihana. Ua hoʻopiha nā huahana i kekahi mau noi diatomite ma Kina.
