Ana buƙatar ton na yashi na 7-9% oxalic acid, 1-3% hydrofluoric acid da 90% cakuda ruwa;Yana buƙatar ton 2-3.5 na ruwa, idan an sake yin amfani da ruwan, to, ton 0.1 na ruwa kawai ake buƙata don tsaftace tan na yashi, a cikin aikin tsaftace yashi, ba makawa zai kawo yawancin yashi;Maganin tsinken yashi na quartz shine a yi maganin yashi quartz tare da hydrochloric acid, sulfuric acid, oxalic acid ko hydrofluoric acid don narkar da ƙarfe.

Ⅱ mixing mix

Ana allura maganin pickling a cikin tanki mai tsini kuma a ƙara gwargwadon adadin abun ciki na hydrochloric acid kamar kusan 5% na nauyin yashi don tabbatar da cewa yashi quartz ya jiƙa a cikin maganin pickling kuma abun ciki na hydrochloric acid shine kusan 5% na yashi nauyi.

Ⅲ Yashi quartz mai wanke Acid
① Lokacin yashi ma'adini don jiƙa maganin pickling shine gabaɗayan sa'o'i 3-5, takamaiman buƙatar ƙara ko rage lokacin jiƙa bisa ga launin rawaya na yashi quartz, ko maganin pickling da yashi ma'adini za a iya motsa shi na ɗan lokaci. na lokaci, sannan yin amfani da kayan aikin dumama don dumama maganin zuwa wani zafin jiki, na iya rage lokacin tsinke.

② Yin amfani da oxalic acid da kore alum a matsayin rage wakili pickling magani zai iya inganta solubility na baƙin ƙarfe, bi da bi, ruwa, oxalic acid, koren alum daidai da rabo daga cikin bayani a wani zafin jiki, ma'adini yashi da bayani daidai da tare da wani nau'i na haɗuwa, motsawa, jiyya na 'yan mintoci kaɗan, an tace maganin kuma a bi da shi bayan dawowa.

③ Hydrofluoric acid magani: Sakamakon yana da kyau lokacin da ake amfani da maganin hydrofluoric acid kadai, amma ƙaddamarwa ya fi girma.Lokacin da aka raba tare da sodium dithionite, za a iya amfani da ƙananan ƙwayoyin hydrofluoric acid.

An gauraya wani yanki na acid hydrochloric da hydrofluoric acid a cikin yashi ma'adini a lokaci guda bisa ga rabo;Hakanan za'a iya magance ta da maganin hydrochloric acid da farko, a wanke sannan a shayar da shi da hydrofluoric acid, a kula da shi a zafin jiki na tsawon sa'o'i 2-3, sannan a tace a tsaftace.

Lura:

Idan ana amfani da acid hydrofluoric don acid jiƙa yashi quartz, abin da ya faru ya fi rikitarwa.Baya ga rushewar baƙin ƙarfe a cikin kafofin watsa labaru na acidic, HF kuma na iya amsawa tare da ma'adini da kanta don narkar da SiO2 da sauran silicates na wani kauri a saman.

Duk da haka, wannan ya fi tasiri don tsaftace saman yashi ma'adini da kuma kawar da baƙin ƙarfe da sauran ƙazanta, don haka hydrofluoric acid yana da kyau ga acid leaching na quartz.Duk da haka, HF yana da guba kuma yana da lalacewa sosai, don haka ruwan datti na acid yana buƙatar kulawa ta musamman.

Iv Acid farfadowa da deacidification

Kurkura yashi ma'adini da aka wanke da ruwa sau 2-3, sa'an nan kuma neutralize da 0.05% -0.5% na sodium hydroxide (caustic soda) alkaline bayani, da neutralization lokaci ne game da 30-60 minutes, da kuma tabbatar da cewa duk ma'adini. yashi ne neutralized a wurin.Lokacin da pH ya kai alkaline, zaku iya sakin lye kuma ku wanke sau 1-2 har sai pH ya kasance tsaka tsaki.

Ⅴ Bushewar yashi quartz

Ya kamata a zubar da yashi na quartz daga ruwa bayan cire acid, sa'an nan kuma a bushe yashin ma'adini a cikin kayan bushewa.

Ⅵ nunawa, zaɓin launi da marufi, da sauransu.

Na sama shi ne ainihin tsari na ma'adini yashi pickling da leaching magani tsari, ma'adini yashi tama yana da in mun gwada da m rarraba a kasar mu, don haka akwai bambance-bambance a cikin yanayin ma'adini yashi, a cikin tsarkakewa na ma'adini yashi kuma bukatar musamman matsaloli musamman. bincike, haɓaka tsarin tsarkakewa yashi ma'adini mai dacewa.
