Ana mayar da ma'adanai na rukunin Kyanite zuwa cakuda mullite (wanda aka fi sani da mullite) da silica (cristobalite) bayan an yi musu calcination a yanayin zafi mai yawa, kuma ana ƙara yawan su. Ma'adanai masu alaƙa sun haɗa da biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite da sauran ma'adanai.

Yankunan aikace-aikace da alamun fasaha

Kayan da ke hana ruwa su ne manyan fannoni na amfani da ma'adanai na kyanite, waɗanda za a iya amfani da su wajen yin tubali, inganta aikin zafin jiki mai yawa na samfuran da ke hana ruwa, haɗa mullite a yanayin zafi mai yawa, kuma ana iya amfani da kyanite da andalusite masu haske a matsayin duwatsu masu daraja ko kayan aikin hannu.

Babban amfani da ma'adanai na kyanite:

Saboda bambance-bambancen aiki na kayan albarkatun ma'adinai daban-daban, amfani da matakan aiwatar da aikace-aikacen, akwai buƙatu daban-daban don ingancin kyanite concentrates.

Fasahar sarrafawa - ingantawa da tsarkakewa

Hanyar beneficiation da tsarin fasaha na ma'adanai kyanite galibi sun dogara ne akan halayen ma'adanai da aka haɗa, gabaɗaya flotation, rabuwar nauyi da rabuwar maganadisu, da sauransu.

① Shawagi a kan ruwa

Flotation ita ce babbar hanyar amfani da ma'adanai na kyanite, amma gabaɗaya yana buƙatar a haɗa shi da wasu hanyoyi don biyan buƙatun ma'aunin masana'antu. Sau da yawa ana amfani da desliming na nauyi ko flotation bayan rabuwar maganadisu. Masu tattarawa suna amfani da fatty acids da gishirinsu, ƙimar PH na ɓangaren litattafan almara mai tsaka tsaki ko mai rauni, manyan abubuwan da ke tasiri sune ƙanƙantar niƙa, halayen ƙazanta, tasirin desliming, tsarin sinadarai da ƙimar PH na ɓangaren litattafan almara.

②Sake zaɓar

Ga ma'adanai masu kauri da kuma gauraye masu kyanite, galibi ana amfani da hanyar raba nauyi, kuma kayan aikin raba nauyi sun haɗa da tebur mai girgiza, guguwa, matsakaicin nauyi da kuma magudanar ruwa mai karkace.

③Hanyar rabuwar maganadisu

Hanya ce mai matuƙar muhimmanci wajen amfani da kyanite. Ana amfani da ita gabaɗaya don shirya kayan da aka zaɓa don dawo da su ko cire samfuran maganadisu, ko kuma don ayyukan sake sarrafa abubuwa don cire ƙazanta kamar ƙarfe da titanium da kuma inganta matakin tattarawa. Kayan aikin rabuwar maganadisu sun haɗa da raba maganadisu na drum, raba maganadisu na farantin, raba maganadisu na tsaye mai tsayi, da sauransu. Ana ƙayyade kayan aikin rabuwar maganadisu da kwararar aiki gwargwadon ƙarfin maganadisu na ƙazanta.

Mulite na roba

Mullite abu ne mai inganci mai hana ruwa gudu. Akwai hanyoyi guda biyu don haɗa mullite daga kayan kwalliyar kyanite. Ɗaya shine a haɗa calcine kai tsaye don samar da clinker mai matsakaicin aluminum, ɗayan kuma shine a ƙara bauxite, alumina da zircon. Ana sanya duwatsu, da sauransu a yanayin zafi mai yawa don samar da clinker mullite ko zircon mullite.
