Bauxite (bauxite ore) inoreva izwi rakaunganidzwa rezvicherwa zvinogona kushandiswa muindasitiri, kunyanya inoumbwa negibbsite, boehmite, kana diaspore. Icho chinhu chisingadzokerikezve sosi. Bauxite yakachena muruvara uye inogona kuoneka grey, yakasvibira, kana yakatsvuka nekuda kwetsvina yakasiyana. Bauxite ine huwandu hwakasiyana hwemaindasitiri ekushandisa. Kune rimwe divi, ndiyo huru yezvigadzirwa zvekugadzira alumina, iyo inozoburitsa aluminium. Nekune rimwe divi, inoshandiswa zvakanyanya seyakagadzirwa mumaindasitiri senge refractory zvinhu, fused corundum, kukuya zvinhu, zvigadzirwa zveceramic, zvigadzirwa zvemakemikari, uye yakakwira alumina slurry.

Calcined bauxite contains hydrated alumina and aluminum hydroxide, obtained by calcining high-quality bauxite at high temperatures (85°C to 1600°C) in a rotary kiln. It is one of the main raw materials for producing aluminum. Compared with the original bauxite, after removing moisture through calcination, the alumina content of the calcined bauxite can be increased from about 57% to 58% of the original bauxite to 84% to 88%.

Applications

Indasitiri yeAluminium: bauxite ine aruminiyamu yakakwira zvirimo uye chinhu chakakosha mbishi kuindasitiri yekunyungudutsa aluminium;
2. Precision casting: bauxite inogona kuitwa mumhando dzakasiyana-siyana dzekukanda mold mushure mekugadzirisa, inonyanya kushandiswa mukukurukurirana, kushandiswa, michina uye maindasitiri emidziyo;
3. Refractory material: bauxite ine zvinhu zvakanaka zvakadai sekuderera kwekuwedzera kwekushisa, kupikisa kwepamusoro, uye kugadzikana kwekushisa kwepamusoro, zvichiita kuti ive yakajairika mbishi yezvinhu zvinoramba. Refractory zvinhu zvakagadzirwa nayo zvinoshandiswa zvakanyanya musimbi, isiri-ferrous simbi, petroleum, makemikari uye mamwe maindasitiri minda.
4. Zvishandiso zvekuvaka: bauxite poda inogona kuvandudza kusimba uye kuoma kwezvinhu zvakaita sesimende, dhaka, uye kongiri, ukuwo ichiwedzera kusimba uye kusagadzikana kwekuora.
