Abstract
Изобретение предлагает способ количественного анализа пробы минерала для определения концентрации выбранных металлов в пробе, содержащий стадии приготовления пробы измельченного минерала, смешивания этой пробы с флюсом, предварительного нагревания реакционного сосуда до температуры, которая приближается к точке плавления флюса, введения смеси из пробы минерала и флюса в тигель, за счет чего смесь переводится в расплавленное состояние для захвата металла, подлежащего анализу, улавливающим материалом, и отделения шлака от улавливающего материала.Отчет о международном поиске был опубликован 2002.05.10.The invention provides a method for quantitative analysis of a mineral sample to determine the concentration of selected metals in a sample, comprising the steps of preparing a ground mineral sample, mixing this sample with the flux, preheating the reaction vessel to a temperature that approaches the melting point of the flux, and introducing the mixture from the mineral sample and the flux crucible, due to which the mixture is transferred to the molten state to capture the metal to be analyzed, the trapping material, and the separation of the slag from the trapping th material. The report on the international search was published 2002.05.10.
