Appraisal of the method of determining micro-hardness by means of the Reichert micro-hardness tester

Author: Gaigher, JL Date: 1972 During tests on the characteristics of magnetites use was made of the Reichert Micro-Hardness Tester. Read more
Interim report on mineral matter in coal - the reactivity of the mineral matter at room temperature

Author: Gaigher, JL Date: 1977 This report deals with the reactivity of mineral matter prepared from coal by the radio-frequency oxidation method, with the using X-ray diffraction to detect mineral phase changes, and possible react ion mechanisms. Read more
Interim report on minerals in coal - The direct determination of the mineral matter content in some coal product samples

Author: Gaigher, JL Date: 1976 The mineral matter factors for some coal product samples determined by the method of radio--frequency oxidation, compared with results from an earlier survey (Technical Memorandum No021 of 1971), appear to have an acceptable precision. Read more
Mineral matter factors for fifty size coal product samples

Author: Gaigher, JL Date: 1977 The regional variation of mineral matter to ash ratios for some coal product samples is discussed by means of frequency weighted histograms. Read more
Report no. 3 of 1976 the grain-size distribution of the mineral matter in a sample of -0.5 mm + 200 = Landau coal

Author: Gaigher, JL Date: 1976 This report discusses an investigation of radio frequency ashing, micro-sieving in an ultrasonic bath and X-ray diffraction analysis, it is possible to determine the grain-size distribution of the mineral matter in a coal sample. Read more
