ISO 12743:1998 硫化铜、铅和锌精矿 金属和湿度含量测定的取样程序

This International Standard sets out the basic methods for sampling copper, lead and zinc concentrates from moving streams and stationary lots, including stopped-belt sampling, to provide samples for chemical analysis, physical testing and determination of moisture content in accordance with the relevant International Standards. Where the concentrates are susceptible to significant oxidation or decomposition, it is necessary to use a common sample for moisture determination and chemical analysis to eliminate bias (see ISO 10251). In such cases, the common sample needs to be sufficiently representative, i.e. unbiased and sufficiently precise, for chemical analysis and determination of moisture content. Any large agglomerates (>10 mm) present in the primary sample are crushed prior to further sample processing. Sampling of concentrates in slurry form is specifically excluded from this International Standard. Stopped-belt sampling is the reference method for collecting concentrate samples against which mechanical and manual sampling procedures may be compared. Sampling from moving streams is the preferred method. Both falling-stream and cross-belt samplers are described. Sampling from stationary lots is used only where sampling from moving streams is not possible. The procedures described in this International Standard for sampling from stationary lots only minimize some of the systematic sampling errors.

ISO 10251:1997 硫化铜、铅和锌精矿 散装物料干燥过程中质量损失的测定

This International Standard specifies methods for the determination of moisture content of a lot of copper, lead or zinc sulfide concentrate, defined as the percentage mass loss of the moisture test portion under the conditions of drying specified in this document. NOTE 1 In order to obtain an unbiased estimate of the metal content of the lot, it is important that the same drying conditions are used for the determination of bulk and hygroscopic moisture or for preparing a predried test portion. This International Standard is not applicable to drying samples used for determination of volatile elements such as mercury and sulfur. Such samples are allowed to dry at ambient temperature and a hygroscopic moisture determination is carried out in accordance with ISO 9599 at the time of chemical analysis.

ISO 13292:1997 硫化铜、铅和锌精矿 检查取样偏差的试验方法

This International Standard specifies methods for checking whether there is any bias in the sampling of copper, lead, zinc and nickel concentrates, where the sampling is carried out in accordance with the methods specified in ISO 12743. These methods can also be used for comparing alternative sampling regimes, checking whether there is any bias in sample processing and for checking possible significant differences in sampling at different places, e.g. at loading and discharge points, or the analysis of exchange samples. Numerical examples are given in Annex A.

ISO 12745:1996 铜、铅和锌矿石及精矿 质量测定方法的精度和偏差

This International Standard provides guidelines to test for bias over a wide range of mass measurement techniques, to estimate the precision for each tech-nique and to calculate the precision for wet mass when estimated by applying one of those techniques. The guidelines are based on the application of statisti-cal tests to verify that a mass measurement tech-nique is unbiased, to estimate the variance as the most basic measure for its precision and to check the linearity of a static scale over its working range. Cali-bration methods and performance tests for compli-ance with applicable regulations generate test results that can be used to quantify precision and bias for each of these mass measurement techniques and to verify linearity for static weighing devices. The guidelines apply to mass measurement tech-niques used to estimate the wet mass for cargoes or shipments of mineral concentrate as the basis for freight and insurance charges and for preliminary payments or for final settlements between trading partners. The application of static scales requires that at least one certified weight with a mass of no less than one (1) tonne be either available on location or brought in for calibration purposes, and that this certified weight be applicable to the scale in accordance with the manufacturer's recommendations. A set of certified weights covering the entire working range of a weighing device simplifies the process of verifying its state of calibration, estimating its precision as a func-tion of applied load and testing its linearity over the working range.
