Mill chemistry. The crushed and ground ore, or the underground ore in the case of ISL mining, is leached with sulfuric acid: UO 3 + 2H + ====> UO 2 2+ + H 2 O UO 2 2+ + 3SO 4 2-====> UO 2 (SO 4) 3 4-. The UO 2 is oxidised to UO 3.. With some ores, carbonate leaching is used to form a soluble uranyl tricarbonate ion: UO 2 (CO 3) 3 4-.This can then be precipitated with an alkali,

Rock Types of the Windfall deposit. The rock types in the Windfall deposit are divided into two groups: 1) synvolcanic rocks that form part of the Macho Formation (ca. 2717 Ma), and 2) syntectonic rocks that intrude the volcanic sequence and are part of a regional tectonic-magmatic event at ca. 2698 Ma.
