ABSTRACT Berthierine,a 7 A pe-Al memberof the serpentinegroup, occursin the footwall stringerzone of the ArcheanKidd Creek massivesulfide deposit, Ontario, associated with quartz,muscovite, chlorite, pyrite, sphalerite,chalcopyrite, and local tourmaline' cassiterite,and halloysite. Berthierine has been identified by the lack of 14A basalreflections on X-ray powderdiffractionpattems, by its composition (electron-microprobedata), and by transmissionelectron microscopy (TEM). Peoogaphic and scanning eiectronmicroscopic (SEM) studiesreveal different types of berthierineocculrences, including interlayerswithin and rims on deformedchlorite, intergrowthswith muscoviteand halloysite,and discretecoarse grains. TEM imagesshow thick packetsof berthierineand chlorite that are parallel or relatedby low-angle boundaries,and layer terminationsof chlorite by berthierine; mixedJayer chlorite-berthierinealso is observed,intergrown with Fe-rich chlorite and berthierine.End-member (Mg-free) berthierineis presentin small domainsin two samples.The Kidd Creekberthierine is chemicallysimilar -

GEOCHEMISTRY OF FLUORITE AND RELATED FEATURES OF THE KUGITANGTOU RIDGE CAVES, TURKMENISTAN VLADIMIR MALTSEV GEOSYSTEM institute, Moscow, Leninsky prospekt, 61/1, Apt.57, RUSSIA VIKTOR KORSHUNOV Geology Department, Moscow State University, Tichvinsky pereulok, 9/12-4-86, RUSSIA This paper presents a model explaining the fluorine geochemistry in the Cupp-Coutunn Cave System, in the Kugitangtou Ridge, southeastern Turkmenistan. By the corrosive activity of biologically derived sul- furic acid, HF gas is released by weathering of fluorite in residual cave deposits and in speleothems formed during a period of thermal activity. Secondary fluorite is produced, and conditions are provided for silica and aluminum mobility in the caves. The latter process helps to explain the origin of the clay mineral sauconite, Zn3(Si4O10)(OH)2·nH2O, and fraipontite, (Zn,Al)3(SiAl)2O5(OH)4, a member of the kaolinite-serpentine group.

Interactions of Clay Minerals and Their Effects on Copper-Gold Flotation Nestor Cruz Beng, Msc in Chemical Engineering
Interactions of Clay Minerals and their Effects on Copper-Gold Flotation Nestor Cruz BEng, MSc in Chemical Engineering A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 Sustainable Minerals Institute Julius Kruttschnitt Mineral Research Centre Abstract The continuous depletion of mineral resources has resulted in the increased processing of low grade complex ores that in some cases contain clay minerals. These gangue minerals are often associated with ores containing copper and gold and can cause problems in mineral flotation. Some of the observations from industry when high clay ores are processed include the high flotation pulp viscosity, over-stable froth or absent froth, and lower grade and recovery. Clay minerals are small flat particles that occur in colloidal size ranges with charges on their surfaces that may change with pH. These characteristics allow them to interact with water, reagents and other gangue minerals present in flotation pulp. Given these properties and interactions it is expected that clay minerals can cause high slurry viscosities and mechanical entrainment contributing to the decline of flotation kinetics and/or dilution of flotation concentrates. Some solutions to high viscosity and entrainment are the dilution of flotation pulp, desliming, and the blending of easy to process ores and problematic ores. However, the dilution of flotation pulp increases water consumption and reduces plant throughput, desliming removes fine valuable minerals as well, and blending ores is also impractical since at some point it is necessary to process the high clay content ores alone. The use of dispersants or depressants to reduce viscosity and entrainment could be an effective way to improve the flotation of this type of ores, but to make the best use of this alternative it is essential to understand at a fundamental level some of the interactions of clay minerals in flotation. -

Triplett The Supervisory Committee certifies that this disquisition complies with North Dakota State University’s regulations and meets the accepted standards for the degree of MASTER OF SCIENCE SUPERVISORY COMMITTEE: Bernhardt Saini -Eidukat Chair Kenneth Lepper Achintya Bezbaruah Lisa Montplaisir Approved: March 7, 2012 Craig Stockwell Date Department Chair ABSTRACT The fibrous zeolite mineral erionite is a concern due to its potential for causing lung disease in humans. Studies have shown that exposure to altered volcanic bedrock containing erionite may be the explanation for a high lung disease rate throughout regions of the world (Metintas et al., 1999). Erionite was reported by Forsman (1986) as occurring in tuffaceous rock units of the Arikaree Formation in the Killdeer Mountains of western North Dakota. Rock and soil samples were collected where zeolite minerals are known or suspected to be present including North and South Killdeer Mountains in Dunn County and West and East Rainy Buttes and White Butte in Slope County. Analysis and identification was carried out using XRD, SEM, and EMPA. Zeolitic material was confirmed in units for both North and South Killdeer Mountains. The chemical compositions of the fibers resulted in a majority being classified as offretite rather than erionite. -
