Pūlehu lākou i pyrite ua hua mai i na aina

Pyrite - i ka inoa o ka pae ana o nā minelala hao, a he huina lakou o ke hooheheeia, mai ka pae o ka piuta, nikala, hao, cobalt, platinum. Nā hui paha e like luaipele a me ka arsenic, a me ka antimony-selenium paha.

Calcination pyrite paipai i ka feedstock ka malamalama ma kala like 'ole, mea hao alohilohi, paakiki no, mai 3 a hiki i 7. ka hao a me ka hao pyrite (FeS2 haʻilula), iʻikeʻia me pyrite, mea he waiwai hanalima maka mea mai a ka sulfur dioxide i (i? Iecaianoaaiiuo aeee). I helehelena, no ka mea pōhaku mea he nui o nā pōaka liʻiliʻi o ka pololei helehelena o yellowish-oho ma ka ano me ka paakiki o ka 6-6.5. Haku mele 'ana maemae pyrite maupaʻa ma kahi o 47 pakeneka hao, a ma kahi o 53 pakeneka luaipele.

Calcination pyrites pu ma ka hooholo ia ana o ka helu o Nine Inch reactions, i ka mua o ka i hoakaka no? Anoe? O ka mea pōhaku hao sulfide a me ka luaipele i loko o ka mahu moku'āina (wela ma kahi o 500 C). A laila, luaipele ohu i combusted, e haawi ana sulfur dioxide i, a me ka hao'okesaside a sulfide haawi hui'okesaside. Ma ke aha sulphide ua wela incompletely, ho okumu i kekahi "ke kukui," a e nā fayalite a me nā waiwai, ke kaumaha ma muli o nā impurities i loko o ka feedstock.

Calcination pyrites e paka i loko o ke kinoea pae i kekahi dala o ke SO3, admixed me ka SO2. Kēia waiwai a hana ma ke ala o ka ipu ka popopo, no laila, e emi i ka SO3 kinoea mahana ma ka mākeke o ke kapuahi lako a pan e ia e pili ana i 850S, a laila, koke ninini i ka 400C.

Pūlehu lākou i pyrite ua hana ia ma na aina, e like me Kēia'ikamu no i ka mea, he pono ole. Ma Rusia, keia mea pōhaku ua o koʻu mau ma Soymenskoy aupuni, Kalitvinskom kahua, e pili ana i Kushva, theological mea kanu ma ka Caucasus, ma ka Ryazan a me Smolensk wahi, a ma nā wahi. Ma kahi e, o ka oi aku kaulana Spanish hoʻokomo kālā (oi loa Aguas Tenidas kahi o ka mea, aole ia i apo ia keleawe, akā, i ka mea kiekie oia ka sulfur maʻiʻo) ua hou exploited i loko o ka ulu ana o ka US, France, Norway, Kuekene. Sulfuric pyrites ma ke ano maoli pinepine admixed arsenic laha 'o ka waiwai, a hoakaka he nui loa nā palapala huikala i loko o ka? Iecaianoaaiiie i loko o ke keena. Nolaila, Manufacturers ho'āʻo e hoʻohana maemae maka mea. No ka laʻana, ka mea Lūkini nā hale hana ma St. Petersburg, e hana ana i loko o Kuekene pyrites.

Pūlehu lākou i ka hao pyrites (a me ka luaipele) ua i ma ka umu, ma ka maka mea ua hanaiia ma ka hoʻohewa paha kīʻamo. Eia, ka mea, ua hui pu ia me ka hū o ka paa mea i mea mua i loko o hoʻopiha (i loko o ka fluidized moe ma ka papa manamana, ma lalo i ke ea ua lako, mai lalo nei), ma hope a ka Nine Inch reactions ana, e haawi ana kinoea (weheʻia) a me ke kukui (ninini he kūikawāʻohe). No hoi, mai ke kapuahi oi wela wehe 'ia ma ka wai anuanu maila' oihana mua.

Calcination pyrite e e holomua ina ka papa luna a me ka lewa hānai mea i lawa ke kiekie. Nolaila, o ka mea pōhaku pinepine hoʻokō 'i loko o ka pulverized moku'āina (i loko o kūpono umu), i ka wa a ka huna nui mea uuku ia i ka oxygen ma ke puana komo i loko o ka ahakanaka o ka waiwai. Eia hou, ke ana wela i ka mana hoʻomalu mea nui no ka mea, pinepine nā minelala hao i loko o kēia papa e sintered ma ke anawela ma luna 900 C. I mea e hoʻoponopono i kēia pilikia ua i hoʻohana like me ka aaioee lepo-ea ukuhiia, i leie aku e hoʻomaka ana i nā mea e kuni i ka mea i mahana i ka 1000 C, i? ienoai aa? iecaianoaaiiie ka hoʻokōʻana.
