Yashi mai wanke-wanke mai acid quartz

Cikakken bayani game da tsarin girkin yashi na quartz da kuma yadda ake girkin

A cikin zaɓin yashi mai tsabta na quartz da yashi mai tsabta na quartz, yana da wuya a cika buƙatun hanyoyin beneficiation na gargajiya, musamman ga fim ɗin ƙarfe mai oxide a saman yashi mai quartz da ƙazanta na ƙarfe a cikin fasa. Domin inganta inganci da yawan amfanin tsarkake yashi mai quartz, tare da halayen yashi mai quartz wanda ba ya narkewa a cikin acid kuma yana narkewa kaɗan a cikin maganin KOH, hanyar cire acid ya zama hanya mai mahimmanci don magance yashi mai quartz.

Maganin tsinken yashi na Quartz shine a yi amfani da sinadarin hydrochloric acid, sulfuric acid, oxalic acid ko hydrofluoric acid don narkar da ƙarfe.

Tsarin asali na tsinken yashi na quartz

Man shafawa mai rage kitse (acid lotion)

Ya kamata a yi tan na yashi da kashi 7-9% na oxalic acid, kashi 1-3% na hydrofluoric acid da kashi 90% na cakuda ruwa; Ana buƙatar tan 2-3.5 na ruwa, idan an sake amfani da ruwan, to ana buƙatar tan 0.1 kawai na ruwa don tsaftace tan na yashi, a cikin aikin tsaftace yashi, babu makawa zai kawo mafi yawan yashi; Maganin tsinken yashi na Quartz shine a yi wa yashi na quartz magani da hydrochloric acid, sulfuric acid, oxalic acid ko hydrofluoric acid don narkar da ƙarfe.

Ⅱ Hadin kayan ƙanshi

Ana zuba ruwan tsamin a cikin tankin tsamin sannan a ƙara shi gwargwadon adadin sinadarin hydrochloric acid a matsayin kusan kashi 5% na nauyin yashi domin tabbatar da cewa an jika yashi mai siffar quartz a cikin ruwan tsamin kuma sinadarin hydrochloric acid ya kai kusan kashi 5% na nauyin yashi.

Ⅲ Yashi mai ruwan 'ya'yan itace mai wanki da ruwa
① Lokacin da yashi mai siffar quartz zai jiƙa ruwan 'ya'yan itace gabaɗaya shine awanni 3-5, takamaiman buƙatar ƙara ko rage lokacin jiƙa gwargwadon fatar yashi mai launin rawaya, ko kuma ana iya motsa ruwan 'ya'yan itace mai siffar quartz na ɗan lokaci, sannan a yi amfani da kayan dumama don dumama ruwan zuwa wani zafin jiki, zai iya rage lokacin ɗiban.

② Amfani da sinadarin oxalic acid da kore alum a matsayin maganin rage yawan sinadarin da ke haifar da tsinken ciki na iya inganta narkewar ƙarfe, bi da bi, ruwa, oxalic acid, kore alum daidai da rabon maganin a wani zafin jiki, yashi quartz da kuma maganin daidai da wani rabo na hadawa, juyawa, magani na ƴan mintuna, sannan a tace maganin sannan a yi masa magani bayan an warke.

③ Maganin Hydrofluoric acid: Tasirin yana da kyau idan aka yi amfani da maganin hydrofluoric acid shi kaɗai, amma yawan sinadarin ya fi yawa. Idan aka haɗa shi da sodium dithionite, za a iya amfani da ƙarancin yawan sinadarin hydrofluoric acid.

An haɗa wani yawan sinadarin hydrochloric acid da hydrofluoric acid a cikin ruwan quartz a lokaci guda bisa ga rabon; Haka kuma ana iya magance shi da maganin hydrochloric acid da farko, a wanke sannan a yi masa magani da hydrofluoric acid, a yi masa magani a babban zafin jiki na tsawon awanni 2-3, sannan a tace a tsaftace shi.

Lura:

Idan ana amfani da sinadarin hydrofluoric acid don jiƙa yashi mai siffar acid, amsawar ta fi rikitarwa. Baya ga narkar da ƙarfe a cikin kafofin acid, HF kuma tana iya amsawa da quartz kanta don narkar da SiO2 da sauran silicates na wani kauri a saman.

Duk da haka, wannan ya fi tasiri wajen tsaftace saman yashi na quartz da kuma kawar da baƙin ƙarfe da sauran gurɓataccen ƙazanta, don haka hydrofluoric acid yana da kyau don cire acid daga quartz. Duk da haka, HF yana da guba kuma yana da matuƙar lalata, don haka ruwan sharar da ke zubar da acid yana buƙatar kulawa ta musamman.

iv Farfado da sinadarin acid da kuma rage acidity

Kurkura yashi mai ruwan quartz da aka wanke da ruwa sau 2-3, sannan a tace shi da ruwan alkaline na sodium hydroxide (caustic soda), kuma lokacin rage kiba shine kimanin mintuna 30-60, sannan a tabbatar an tace duk yashi mai ruwan quartz a wurin da yake. Idan pH ya kai alkaline, za a iya fitar da ruwa a wanke sau 1-2 har sai pH ya zama tsaka tsaki.

Ⅴ Busasshen yashi mai siffar quartz

Ya kamata a zubar da yashi mai siffar quartz da ruwa bayan cire acid, sannan a busar da yashi mai siffar quartz a cikin kayan aikin busarwa.

Ⅵ tantancewa, zaɓin launi da marufi, da sauransu.

Abin da ke sama shine tsarin asali na tsinkewar yashi na quartz da kuma tsarin maganin leaching, ma'adinan yashi na quartz yana da rarrabawa mai faɗi a ƙasarmu, don haka akwai bambance-bambance a cikin yanayin yashi na quartz, a cikin tsarkake yashi na quartz kuma yana buƙatar takamaiman matsaloli na musamman bincike, haɓaka tsarin tsarkake yashi na quartz mai dacewa.
