Abubuwan da ke tattare da sinadarai na high alumina bauxite A cikin sinadarai na babban alumina alumina, manyan abubuwan da aka gyara sune Al2O3 da SiO2. An rarraba nau’in sinadarai na yau da kullum bisa ga tsarin sinadaran da kuma amfani da bauxite.
Maki 1 zuwa 6 sun dace da nau’in tama na monohydrate duralumin; Grade 7 ya dace da nau’in aluminum. Al2O3 shine babban sashi a cikin bauxite. Mafi girman abun ciki, mafi kyau. A halin yanzu samar da alumina masana’antu na bukatar cewa rabo daga aluminum zuwa silicon bai kasa da 3.0. Ana ɗaukar sauran oxides azaman ƙazanta.
