bauxite the principal ore of aluminum.bauxite is the principal ore of aluminum. the first step in producing aluminum is to crush the bauxite and purify it using the bayer process. in the bayer process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.g processing methods g ore extractionsep , · of all the methods of extracting g processing it from its ore, i used a few to evaluate two principal flowsheets in this case study. the flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets.bauxite ore britannicabauxite, rock largely composed of a mixture of hydrous aluminum oxides.bauxite is the principal ore of aluminum.. bauxites vary physically according to the origin and geologic history of their deposits some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic, or pealike; still others are porous but strong or are stratified or largely pseudomorphic afterunderground hardrock mining underground hardrock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing g, silver, iron, copper, zinc, nickel, tin, and lead.it also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. softrock mining refers to the excavation of softer minerals, such as salt
