Process and installation for the manufacture of sand for use in "shell" casting, characterized in that the process comprises: a first phase, in which dry and washed sand is mixed with hexamethylene tetramine, as a catalyst, for a time of approximately two to five minutes; a second phase in which bentonite and iron oxide are added, making the mixture for about five minutes; a third phase, in which, the previous mixture is homogenized, dissolved phenolic resin is incorporated, mixing the whole for approximately fifteen minutes, accelerating the impregnation process by adding hot air; and, finally, a few minutes before finishing that third phase of the process, calcium stearate is added, to end up passing the mixture to a vibrating screen.
