ʻO ka sodium sulfide kekahi pilikia, akā i kekahi ʻoihana paʻi a me ka hoʻoluʻu ʻana, ʻo ka ʻoihana textile kahi ʻāpana pono ʻole, pono a me nā hemahema, ʻaʻohe mea hana hou i nā huahana maikaʻi a i ʻole nā ​​​​mea hana, e loaʻa i kā lākou mau hemahema, ʻaʻole ʻokoʻa ka sodium sulfide, he corrosive, mākou. i ka hoʻohana ʻana i kēlā me kēia lā, pono e mālama pono iā ʻoe iho. E kaʻana like i kekahi ʻike e pili ana i ke ʻano huahana electroproduct leaching.

Ma muli o ka hōʻiliʻili ʻana o ka sodium sulfate i ka wai ʻōpala anode, pili ia i ka hana electroproduct maʻamau a pono e hoʻomaʻemaʻe ʻia. Hiki ke hoʻokaʻawale ʻia kahi ʻāpana o ka wai anode no ka evaporation a me ka neʻe ʻana, crystallization o ka sodium sulfate ma muli o ka paʻakai coagulation, hiki ke mālama hou ʻia ka sodium a i ʻole nā ​​​​huahana.

Aia ka leaching slag he 32% -35% ke kēpau, a aia nō ke kēpau i ke kūlana kemika. ʻO ka ʻoiaʻiʻo, ʻo ia kahi ʻano kumu alakaʻi maikaʻi ʻole a hiki ke mālama ʻia me ka hoʻokahi a i ʻole me ka nui o ke kēpau. ʻO ke ʻano lapaʻau o kēia manawa ʻo ia ka hoʻomaʻemaʻe i ke kēpau i loko o ka concentrate lead.

ʻO nā mea maikaʻi o kēia ʻano hana ʻo ia ka hoʻohana ʻana i ka sodium sulfide ma ke ʻano he leaching agent he koho maikaʻi. Ma ke kaʻina hana leaching o ke alakaʻi paving concentrate, ua hoʻoheheʻe ʻia ka antimony a waiho ʻia ke kēpau a me ke kālā i loko o ka leaching slag, a hiki ke hoʻokaʻawale loa ʻia ke alakaʻi a me ka antimony i hoʻokahi hana, a hiki ke pale ʻia ka haumia o ka lewa o SO2 flue gas.

ʻO nā hemahema o kēia ʻano: ma muli o ka paʻakikī paʻakikī o ka hoʻokumu ʻana, ka helu electroproduct maikaʻi ʻole, ka haʻahaʻa haʻahaʻa o kēia manawa (68% -70%) wale nō, ʻo ke koena antimony he kiʻekiʻe ka alkali a me ka haʻahaʻa haʻahaʻa haʻahaʻa (33% -38%) wale nō, paʻakikī ke hoʻomaʻemaʻe pololei i ke kēpau; Eia kekahi, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka alkali, a ʻo ka sodium sulfide i kēlā me kēia ton o ka cathode antimony a hiki i 1-1.3t. No ka mea ʻaʻole hiki ke hoʻoponopono maikaʻi ʻia nā hemahema i luna, no laila, ʻoiai ua hoʻāʻo mākou e hoʻohana i kēia ʻano hana no ka hana ʻana, kūkulu i ka hale hana hoʻāʻo, a ʻo kekahi mau hale hana i hoʻāʻo e hoʻonohonoho i nā hale hana e like me kēia ʻano, akā ʻaʻole i hana. Eia nō naʻe, ma muli o ka hoʻokaʻawale loa ʻana o ke alapiʻi alakaʻi i ka manawa hoʻokahi, ua hoʻihoʻi ʻia nā metala pili āpau i ka concentrate, no laila he ʻano ʻano metallurgical pollution-free kūpono e noiʻi hohonu mai ka hoʻohana piha ʻana a me ka hoʻopau ʻana i ka uahi sulfur. haumia.

Ma luna aʻe ka hoʻolauna ʻana i ke ʻano leaching electrode o ka sodium sulfide. Inā makemake ʻoe a makemake paha ʻoe, hiki iā ʻoe ke kelepona i kā mākou hotline no ke kūkākūkā. E hāʻawi mākou iā ʻoe i nā huahana hana maikaʻi loa, ʻaʻole ia e hoʻokuʻu iā ʻoe
