SAMPLING METHOD MB1 SAMPLING OF STOCKPILES 1 SCOPE This method describes the procedure to be followed when stockpiles are sampled (see 6.1). The stockpiles may consist of: Natural gravel, soil or sand; Crushed rock for base or subbase; Screened-out crusher dust for binder, fine aggregate for concrete or fine
ISO 2859-4:2002 establishes the sampling plans and the procedures that can be used to assess whether the quality level of an entity (lot, process, etc) conforms to a declared value. The sampling plans have been devised so as to obtain a risk of less than 5 % of contradicting a correct declared ...

Mar 01, 2014· The procedures described in this International Standard apply to sampling of iron ore that is transported in moving streams as a slurry. These streams can fall freely or be confined in pipes, launders, chutes, spirals, or similar channels. Sampling of slurries in pressurized pipes is not covered in this International Standard.
Ore Sampling Methods: Good & Proper View Larger Image From the old-fashioned “ grab-sample ” to the modern timing- device, which takes a machine-sample with mathematical precision, there is a wide gap, which was only crossed by many years of toil and unremitting endeavor.
Sets out requirements for the sampling from moving streams and stationary situations, including stopped-belt sampling, to provide gross samples for sample preparation. The procedures recommended may not be applicable in cases of extreme segregation, e.g. very wet ore due to its sticky nature, or very dry ore due to generation of dust.
1. Introduction. The use of correct sampling and sample preparation practice is critical to the accurate delineation of ore resources as well as the evaluation and control of subsequent processing operations from mining through to delivery of the final product (François-Bongarçon and Gy, 2002, Holmes, 2002, Holmes, 2004, Holmes, 2010, Holmes, 2013).
In the table, below, is a basic sampling equation that relates particle size to the amount of sample to be taken, with constants derrived for varions types of ore bodies. The values for "M" are the sample size required in pounds. Tha values of k are the constant derrived for differing ore …
ISO 2859-10 was prepared by Technical Committee ISO/TC 69, Applications of statistical methods, Subcommittee SC 5, Acceptance sampling. This first edition of ISO 2859-10 cancels and replaces ISO 2859-0:1995, which has been technically revised. ISO 2859 consists of the following parts, under the general title Sampling procedures for inspection by
