Abstract
1. Способ определения золотоносности рудных минералов по выявлению в них содержания золота с использованием инструментальных методов, отличающийся тем, что осуществляют нейтронно-активационный анализ образца золотоносных сульфидов, формируют пробу в виде его зерна размером от 30-70 мкм которую последовательно запаивают в полиэтиленовую пленку, упаковывают в фильтровальную бумагу и алюминиевую фольгу, подготовленную таким образом пробу подвергают облучению на реакторе в течение 15-17 ч в потоке 1·10н/см·с с последующим измерением в образце наведенной активности золота и его сателлитов на 7-12 день после облучения, параллельно с диапазоном измеряемой энергии 100-1800 КэВ и 50-160 КэВ по линии соответственно 1332 КэВ и 121,8 КэВ, после чего анализируют интенсивность ν - линии золота при 412 КэВ и путем сравнения с интенсивностью этой же линии в эталонных образцах рассчитывают количество золота в зернах.2. Способ по п.1, отличающийся тем, что в качестве золотоносных сульфидов используют сульфидную группу пирита.1. A method for determining the gold content of ore minerals by detecting the gold content in them using instrumental methods, characterized in that they perform neutron activation analysis of a sample of gold-bearing sulfides, form a sample in the form of its grain with a size of 30-70 microns, which is sequentially sealed in a plastic film, packed in filter paper and aluminum foil, the sample thus prepared is subjected to irradiation in the reactor for 15-17 hours in a flow of 1 · 10n / cm · s, followed by measurement in the sample the induced activity of gold and its satellites on days 7-12 after irradiation, in parallel with the measured energy range of 100-1800 keV and 50-160 keV along the line of 1332 keV and 121.8 keV, respectively, after which the intensity of the ν - gold line at 412 keV is analyzed and by comparing with the intensity of the same line in the reference samples, the amount of gold in the grains is calculated. 2. The method according to claim 1, characterized in that the sulfide group of pyrite is used as gold-bearing sulfides.
