Kaolin ine nzvimbo dzakawanda dzakachengetedzwa munyika yangu, uye nzvimbo dzakasimbiswa dzekuchengetedza zvakatipoteredza dzinosvika mabhiriyoni matatu ematani, dzinonyanya kupararira muGuangdong, Guangxi, Jiangxi, Fujian, Jiangsu nedzimwe nzvimbo. Nekuda kwezvikonzero zvakasiyana zvekugadzirwa kwezvakatipoteredza, kuumbwa uye chimiro chekaolin kubva munzvimbo dzakasiyana dzekugadzira zvakasiyanawo. Kaolin isimbi ine layered silicate yerudzi rwe1:1, iyo inoumbwa neoctahedron netetrahedron. Zvikamu zvayo zvikuru iSiO2 neAl203. Inewo huwandu hushoma hweFe203, Ti02, MgO, CaO, K2O neNa2O, nezvimwewo. Kaolin ine zvakawanda zvakanaka zvemuviri nemakemikari uye maitiro ekushanda, saka inoshandiswa zvakanyanya mumafuta epetrochemicals, kugadzira mapepa, zvinhu zvinoshanda, kuputira, ceramics, zvinhu zvisingapindi mvura, nezvimwewo. Nekufambira mberi kwesainzi netekinoroji yemazuva ano, kushandiswa kutsva kwekaolin kuri kuramba kuchiwedzera, uye kuri kutanga kupinda muminda yakakwirira, chaiyo uye yemazuva ano. Kaolin ore ine huwandu hushoma (kazhinji 0.5% kusvika 3%) hwezvicherwa zvesimbi (iron oxides, ilmenite, siderite, pyrite, mica, tourmaline, nezvimwewo), izvo zvinoisa ruvara pa kaolin uye zvinokanganisa kuchena kwayo uye zvimwe zvinhu zvinoganhurira kushandiswa kwe kaolin. Nokudaro, kuongororwa kwechimiro che kaolin uye tsvakiridzo ye tekinoroji yayo yekubvisa tsvina kwakakosha zvikuru. Tsvina idzi dzine mavara dzinowanzova nemasimba asina simba emagnetic uye dzinogona kubviswa nekupatsanurwa kwemagnetic. Kupatsanurwa kwemagnetic inzira yekuparadzanisa zvicherwa zvemineral mumunda wemagineti uchishandisa musiyano wemagineti wemagineti. Kune zvicherwa zvine simba remagnetic, simba remagnetic rakasimba rinodiwa kuti magnetic separation ishande.
