The use of a penetrant dye to study ore permeability [electronic resource] / S. Kaiman, Extraction Metallurgy Division. On the use of a penetrant dye to study ore permeability Ottawa : Information Canada, 1973. iii, 8 p. : ill. Technical bulletin ; TB 165 Cover title. "January 1973." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “Tests showed that fractures and porous mineral constituents in rock specimens can be revealed by wetting the specimens with Zyglo, a surface-active oil. The fluorescence of Zyglo under ultraviolet light makes it possible to study the extent of its penetration and thus to assess the permeability of the ore. Application of the technique to a radioactive conglomerate confirmed the suspected co-incidence of permeable zones in the ore and uranium mineral concentrations. This could explain the amenability of the ore to leaching"--Abstract, p. i. Includes abstract in French. gccst Minerals gccst Metals gccst Measurement Canada. Natural Resources Canada. Canada.
