Abstract
Three representative samples from a section on the Belterra Clays – ABT, the cover of bauxite from the Miltônia mine in Paragominas, state of Pará, were investigated for their mineralogical composition, multielement chemistry and spectrum of heavy minerals. The results showed the dominance of kaolinite, goethite, hematite, quartz and even anatase, and consequent dominance of SiO2, Al2O3, Fe2O3 and TiO2. Trace element concentrations are at or below the crustal level, except for those elements concentrated by lateritic processes. The main heavy minerals are zircon, rutile and tourmaline, the ZTR. These data show that the investigated ABT is similar to those of other bauxite deposits in Pará
