含贵金属粉末物料样品制备方法
摘要：
本发明涉及贵金属二次资源综合回收利用领域，尤其涉及含贵金属粉末物料样品制备方法。含贵金属粉末物料样品制备方法，按如下步骤依次进行：A、物料混合；B、缩分取样；C、样品干燥及水分测定；D、样品研磨；E、三维混料器混料；F、样品八分。本发明能保证从取样得到的小量样品及小批量贵金属粉末物料进行样品制备，得到少于100克样品，保证最终样品具有代表性和适合分析检测。
摘要（英）：

The invention relates to the field of secondary resource comprehensive recycling of precious metal, in particular to a preparation method for samples containing precious metal powder materials. The preparation method for the samples containing the precious metal powder materials is implemented through the following steps sequentially: A, material mixing; B, splitting and sampling; C, sample drying and moisture determination; D, sample grinding; E, blending with a three-dimensional blender; F, forming of eight uniform samples by sample splitting. With adoption of the method, less than 100 g of samples can be obtained through sample preparation from a small quantity of samples and small batch of precious metal powder materials obtained through sampling, and the final samples are representative and suitable for analysis and detection.
