Mineral Investigation of the Lime Hills, Narrows, and Sand Cove Wilderness Study Areas, Mohave County, Arizona
From introduction: During 1981 the Bureau of Mines conducted a field investigation of the Bureau of Land Management's Lime Hills, Narrows, and Sand Cove Wilderness Study Areas (WSA's), Mohave County, Arizona as part of a joint effort with the Geological Survey to make a mineral survey of the area. Surface workings and outcrops were examined and samples taken from rock sections that appeared to represent most of the mineralized area. Complete analytical results and sample descriptions are available for public inspection at the Bureau of Mines, Intermountain Field Operations Center, Building 20, Denver Federal Center, Denver, Colo. Part of the area also was examined and sampled in 1979 by L. W. Hamm, Bureau of Mines (Villalobos and Hamm, 1980), during a mineral resource study of the Paiute Primitive Area.

Petrographic and Geochemical Analyses of Leach Samples from Artillery Peak, Mohave County, Arizona
Abstract: The first step in determining whether Mn can be recovered by in situ leaching is to develop and test a selective lixiviant. Two column leach tests and one core leach test were conducted by the U.S. Bureau of Mines on Mn oxide ore using aqueous sulfur dioxide (SO2) as the lixiviant. The column tests showed that aqueous SO2 could selectively dissolve available Mn oxides from calcite-rich ore in a heap leach system. However, the core test showed that calcite gangue side reactions can have pronounced negative effects on the likelihood of successful in situ leaching of a calcite-rich ore with aqueous SO2. Petrographic and geochemical analyses showed that both Mn (IV, II) oxides and calcite were dissolved. The abundance of dissolved Ca caused precipitation of gypsum. Acid consumption by calcite dissolution caused a rise in pH that caused the S02/S species to shift to SO32- (sulfite), which hindered reductive dissolution of Mn oxide. Gypsum precipitation did not affect complete leaching of the rock fragments in the column tests; however, it plugged the natural permeability in the core. Manganese recoveries were high for the column tests and low for the core test.
