Item Training and capacity building on the Coastal Climate Change Tool(2023-10) Lück-Vogel, MelanieThis presentation was the baseline for about 20 training workshops to government official on coastal climate change, coastal flood and erosion risk lines and coastal management lines. These workshops were conducted between 2020 and 2023 on behalf of DFFE with funding from the German GIZ and the Benguela Current Convention.Item To ascertain whether a density gradient exists within the Drewboy washer(1963) Erasmus, TC; Du Plessis, HSLThe object of this test was to ascertain whether there exists variation in the specific gravity with special position within the bath of the Drewboy dense medium washer.Item Interim report on the characteristics of the volatile matter of coals(1968) Meintjies, AA; Van Der Berg, FThe object of this investigation was to determine whether a correlation could be found between the known explosive properties of coal dusts and the nature, quantity and temperature dependence of volatile matter formation.Item Anthracite grading(1965) Savage, WHDDuring the past eighteen months discussions have been held with the Anthracite Producers Association on the desirability of altering and introducing a second and possibly a third grade.Item Tests carried out on the drewboy washer during the period February to August 1958(1958) Van der Walt, PJThis paper presents a technical memorandum on tests carried out on the drewboy washer during the period February to August 1958.Item Further full scale coking investigation of Hlobane and Northfield coals on behalf of AMCOR and the Natal Navigation Collieries and Estate Company Limited(1963) La Grange, CCThe first series of tests in this programme was carried out in the letter half of 1962, and the results were communicated in FRI Technical Memorandum No. 21 of 1962.Item Analyses of samples from boreholes 2 and 3 on "Bankfontein 503" near Uitkyk, Transvaal(1936) Hall, PEThese two borehole were sunk by the Minnaar-Witbank Colliery during February 1936.Item Report on magnetic separator tests done on magnetite from Bon Accord for federale vanadium BPK(1963) Gericke, ELThis investigation was done at the request of Federale Vanadium, Bpk., who supplied 6 tons of their magnetic ore for this purpose.Item The drag coefficient of a particle and the voids fraction in fluidization or sedimentation assembly of particles(1971) Bonapace, ACThe drag coefficient of a solitary particle when moving relative to a fluid, when rising or falling vertically in a stationary fluid, is a well-known function of the particle Reynolds number.Item A recording methanometer (prototype)(1966) Meintjies, AAThe document elaborates on a recording methanometer (prototype) that will determine the effect of mining operations and other factors such as changes in atmospheric pressure on the discharge of methane concentration for extended periods.Item Report on dust collector tests at Salt River Power Station during September, 1957(1957) Van Doornum, G.A.W; Van Doornum, GAWThe tests reported herein carried out on behalf of Messrs. Davidson and Company, the suppliers of the dust collecting equipment, for the purpose of determining the performance of the installation.Item A study of some aspects of the scaling of coal in the workings of South African collieries progress report on coal Mining Research at the Fuel Research Institute(1964) Sevenster, PG; Meintjies, AThis paper is concerned with a different type of coal degradation which occur not only in coal already broken from the seam but is also noted on exposed faced in the workings of collieries where it may cause dangerous working conditions.Item Research work by the F.R.I. on Witbank Duff Coals and concerning mainly their upgrading and possible utilization for coking purpose(1968) La Grange, CCThis memorandum contains tables and notes appended which represent information obtained from time to time during investigations concerned with possible production of coking coal from Witbank duffs and other products.Item Interim report on the characteristics of the volatile matter of coals(1967) Meintjies, AAA preliminary study was made of the application of pyrolysis-gas chromatography to coal dust. A correlation between the explosibility index of a coal and the nature of its volatile matter would prove useful.Item A report of the results of two performance tests carried out on a Wemco-drum Dense Medium washing plant at Elandsberg colliery in January, 1961(1961) Van Eck, BThis report details the results of two performance tests carried out on a Wemco-drum Dense Medium washing plant at Elandsberg colliery in January, 1961. As this was the first drum type dense medium separator to be installed in this country for coal beneficiation this Institute was naturally very interested in its performance.Item Combustion tests on South African anthracite and coal(1946) Quass, FWIn order to establish the relative suitable for steam raising purposes of South African anthracite, firing tests were carried out in an experimental furnace on a number of nut size largely on the anthracite.Item A report on the results obtained from washability determinations carried out on a sample of Natal anthracite duff(1963) Streicher, SFThe FRI was requested by the Manager, Natal Anthracite Colliery, to carry out washability determinations on a sample of 5 mm X 0 fines.Item The microscopical evaluation of the coal blends used and the cokes produced therefrom in the I/S series of coking tests carried out at ISCOR(1963) Moodie, BThe first observations carried out on the coke samples were of a quantitative nature, but the desirability of evaluating the coke quantitatively soon became evident.Item Item Effects of selected operating variables on the froth flotation of D.N.C. coal Part II influence of the position of the impeller and the impeller speed on the froth flotation of the coal(1964) Davis, PC; Small, JCA range of experiments was done to investigate the influence of the distance of the impeller from the bottom of the cell on the product yield and ash content of the products.
