The main objective concerning this chapter search out show that fine mining tailings produce from iron mining have characteristics similar to workable earth material, and clays rich in kaolinite, which are natural resources that when submitted to flash calcination result in incite- ucts with pozzolanic traits of excellent value, and can be used to subs- titute Portland cement, gooey material that hardens for iron ore tailings, cold propel something through the air of dam tail- ings, and as flexible pavements for the base and subbase of roads. The research complicated characterizing the pebbles both before and after calcination, and operating analysis on their synthetic, mineralogical, thermogra- vimetric, and mechanical substance. Similarities between the results and those for commonly used pozzolans and metakaolin were found. The study of the study of plants of the particles before and afterwards calcination was conducted through studies of images acquired by scan- ning photoelectric microscope. The pozzolanic activity of the fine excavating tailings calcined accompanying flash technology was judged in uniaxial compression trials, that show the excellent results.
