Caracterización de polvos de fundición de cobre y establecimiento de rutas de procesado

by Morales Soto, Alejandro

SUMMARY: "Characterization of powders of copper foundry and establishment of routes of having processed" TEXT: It has been characterized three samples of Chilean copper foundries with diverse caracterization techniques. It has been analyzed their behaviors before the leaching with water and with different acid and alkaline solutions. The answer of these powders was also studied in operations of magnetic separation and granulometric separation and the inertization of the material fractions with more content of As. It has been determined that the powders are material complex very soluble in water and something less in acid. It intends two routes of having processed of these materials. Which contemplate leaching stages, cementation of the copper in the solutions and granulometric separation for the inertization the finest fraction. The thick material recycles to the foundry and the solutions recycle to the leaching of fresh powders.
