Description: From abstract: Aluminous lateritic soil containing as much as 50 percent of alumina (A120) Is found in several places in the Republic of Haiti. The largest deposits are on the Rochelois Plateau southwest of Miragoane on the Southern Peninsula. Mapping and drilling of the deposits indicate fifteen million long tons in place (dried basis). It is estimated that a minimum of 10 million long tons of this reserve is recoverable. The average chemical composition of this material is as follows: A1203, 46.8 percent; SiO2, 3.4 percent; T1O2, 2.8 percent; Fe20, 21.9 percent ; P206, 0.6 percent ; MnO5, 0.5 percent ; and loss on ignition, 24.1 percent. Other localities in which similar lateritic soil occurs are Beaumont in the Massif de la Hotte ; the vicinity of Savane Zombi in the Massif de la Selle ; and Savane Terre Rouge on the plateau northwest of Gonaives. In none of these regions were large deposits found.
