Summary A by-product of the Becher synthetic rutile process is iron oxide, formed during the aeration reaction which rusts the iron from the reduced ilmenite. This project explored the feasibility…
Summary A device known as a Railhead Gauge was developed to measure and record the profile of the head of a rail while that rail was in-situ in an operating…
Summary The research program describes patterns of vegetation and rock conditions in the vicinity of the heavy mineral sands mining operations of Associated Minerals Consolidated Ltd. at Eneabba, Western Australia.…
Summary The quality of a seismic survey depends on the performance of the energy source. A series of tests in which explosive type, depth, shape and weight of the charge…
Summary A new method of down-hole electromagnetic surveying, called the fixed receiver electromagnetic method, was investigated by both theoretical modelling and field surveys on three massive sulphide deposits in the…
Summary The study concentrated particularly on petrologic aspects of depositional facies and diagenetic features. Characteristic lithologies are described of reef-complex carbonates on a scale that is useful for facies analysis…
Summary The lateritic bauxites of the Darling Range of southwestern Australia vary greatly in chemical and mineralogical properties. This study describes the occurrence and properties of the minerals that constitute Darling Range bauxite and…
Summary This report describes the satisfactory testing and evaluation underground of a Pentax EDM unit. Keywords: electronic distance measuring, underground surveying
Summary The chemical and physical properties of two vermiculites were determined and compared, one from Young River W.A. (primarily a chlorite-vermiculite mixed layer system) and the other from Palabora, South…
Summary With the use of suitable conditions, it is possible to remelt along the toe of a weld which has been subject to fatigue stressing. This effectively removes the accumulated…
Summary Reconnaissance studies indicated the potential of integrated Pb-isotope and trace-element studies of pyrites to help resolve the genesis of Archaean gold deposits and to provide information on their economic…
Summary Sediment and crude oil samples from the Canning Basin and from other locations have been subjected to detailed chemical analysis for compounds which are potentially useful for reconstructing the…
