铁矿石.取样和样品制备过程

[中文适用范围]： 本文件提供了 a) 基本理论，c) 采样系统的设计、安装和操作的基本要求，b) 采样和样品制备的基本原理，以及机械采样、手动采样和从样品中提取样品的基本原理。 大量正在转让。 这是为了确定该批次的化学成分、水分含量、尺寸分布以及其他物理和冶金特性，但使用 ISO 3852（方法 2）获得的堆积密度除外。 本文件中规定的方法适用于通过带式输送机和其他可以安装机械取样器或可以安全进行手动取样的矿石处理设备装载和卸载的批次。 这些方法适用于所有铁矿石，无论是天然的还是加工的（例如精矿和团矿，如球团矿或烧结矿）。 [外文原描述]： ISO 3082:2017 provides a) the underlying theory, b) the basic principles for sampling and preparation of samples, and c) the basic requirements for the design, installation and operation of sampling systems for mechanical sampling, manual sampling and preparation of samples taken from a lot under transfer. This is in order to determine the chemical composition, moisture content, size distribution and other physical and metallurgical properties of the lot, except bulk density obtained using ISO 3852 (Method 2). The methods specified in this document are applicable to both the loading and discharging of a lot by means of belt conveyors and other ore-handling equipment to which a mechanical sampler can be installed or where manual sampling can safely be conducted. The methods are applicable to all iron ores, whether natural or processed (e.g. concentrates and agglomerates, such as pellets or sinters).
