Abstract

See full text

A process to use the tailings as construction material giving it waterproofing characteristics and reduce its cracking is presented. For example, to use the mining tailing as a construction material conceding to it impermeabilizing features, reducing its cracking and increasing its resistance. The main stages of said process are to apply a calcium-containing solution to the soil to be treated; apply a solution that that contains calcite-producing bacteria, to the soil to be treated; optionally, add maltodextrin; and stabilize, compact and dry off the mix.
