摘要
An aecount has been given of the spectrographic method for quantitative determination of minerals, ineluding sample treatment and spectrographic analysis. The former lays emphasis art the requirements of sample preparation and corresponding procedures, while the latter mainly deals with the way to insert the sample into are light and some techniqnes adopted to increase the spectrographic sensitivity of mineral grains and the recovery rate of minerals. It is indieated from the experimental resnlts that this method has been proved valid in practice, with detectable grain size being > 0.01mm and a recovery rate of more than 98% for mineral grains ranging within 0.3 mm in din., and can basically satisfy the demands for geological and seientifle research work.
An account has been given of the spectrographic method for quantitative determination of minerals, including sample treatment and spectrographic analysis. The former lays emphasis on the requirements of sample preparation and corresponding procedures, while the latter mainly deals with the way to insert the sample into arc light and some techniques adopted to increase the spectrographic sensitivity of mineral grains and the recovery rate of minerals. It is indicated from the experimental results that this method has been proved valid in practice, with detectable grain size being > 0.01 mm and a recovery rate of more than 98% for mineral grains ranging within 0.3 mm in dia., and can basically satisfy the demands for geological and scientific research work.
