Ke hoʻololi nei i ka hoʻoheheʻe ʻana, e like me ka mea lubricating pale, ka mahana hana 200-2000 °, Flake graphite crystals he flake like; He metamorphic kēia ma lalo o ke kiʻekiʻe o ke kaomi, aia nā unahi nui a me ka unahi maikaʻi. Hōʻike ʻia kēia ʻano o ka graphite ore e ka haʻahaʻa haʻahaʻa, ma waena o 2 ~ 3%, a i ʻole 10 ~ 25%. ʻO ia kekahi o nā ores floatability maikaʻi loa ma ke ʻano. Hiki ke loa'a ka concentrate graphite ki'eki'e ma ka wili a me ka ho'oka'awale 'ana. ʻOi aku ka maikaʻi o ka floatability, lubricity a me ka plasticity o kēia ʻano graphite ma mua o nā ʻano graphite ʻē aʻe; No laila, ʻoi aku ka nui o ka waiwai ʻoihana.
