Standard Test Method for Column Percolation Extraction of Mine Rock by the Meteoric Water Mobility Procedure

Standard Test Method for Column Percolation Extraction of Mine Rock by the Meteoric Water Mobility Procedure

SIGNIFICANCE AND USE
This test method is intended as a means for obtaining an extract from mine rock samples. The extract may be used to estimate the final pH and release of certain constituents of the test sample under the laboratory conditions described in this test method.
The pH of the extraction fluid used in this test method should reflect the pH of precipitation in the geographic region in which the mine rock is being evaluated.
This test method is designed to mobilize potential contaminants present in the solids, so that the resulting extract can be used to assess leachate that could potentially be produced from mine rock in the field.
This test method has not been demonstrated to simulate actual site leaching conditions.
This test method produces extracts that are amenable to the determination of both major and minor (trace) constituents. When minor constituents are being determined, it is especially important that precautions be taken in sample preservation, storage and handling to avoid possible contamination of the extracts.
This test method is a comparative method intended for use as a routine method for monitoring mine rock. It is assumed that all who use this method will be trained analysts capable of performing skillfully and safely. It is expected that work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E882.
SCOPE
1.1 This test method provides a procedure for the column percolation extraction of mine rock in order to determine the potential for dissolution and mobility of certain constituents by meteoric water.
1.2 This test method is intended to describe the procedure for performing column percolation extractions only. It does not describe all types of sampling and analytical requirements that may be associated with its application.
1.3 The values stated in SI units are to be regarded as the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Guide for Contents of Documentation and Statistical Treatments for Reference Materials for Metals, Ores, and Related Materials

SIGNIFICANCE AND USE
5.1 This guide is intended for use by developers of RMs and CRMs for the metals and mining industries.  
5.2 The guidance is related to uniform procedures and requirements and is intended to prevent the proliferation of widely varying documentation practices, definitions, and terminology. Where the statements in this guide are made as imperatives, it is because the stated practices are fundamental to chemical metrology, not to CRM/RM development.  
5.3 The material in this guide is intended to supplement and to clarify the contents of ISO Guide 31 and to provide guidance specific to the needs of the metals and mining industries.  
5.4 The documents described in this guide are intended to contain the minimum amount of information required for a user to understand the material, to help a user judge the quality of the product, and to help a user employ it in appropriate ways. Neither this guide nor resultant documents are meant to be encyclopedic.  
5.5 Because this document is a standard guide, it is intended to educate those who are involved in laboratory operation, quality system development and maintenance, reference material development, and accreditation of laboratory operations within the scope of a quality system. It must be understood by all parties that the elements of this guide discuss optional practices having numerous choices for accomplishment and documentation. However, this guide does not constitute requirements for assessment and accreditation. An obvious example is statistical evaluation for consensus value and uncertainty calculations, which can take many forms with no single, correct choice for any given case.  
5.6 When using this guide, CRM developers will set goals for the material under development, such as target uncertainties for homogeneity and for overall coverage intervals for assigned values. These choices are based on the intended uses of a CRM. The material, property values, and their uncertainties may or may not meet the set goals...
SCOPE
1.1 This guide is designed to explain and to clarify documentation that accompanies an RM or a certified reference material (CRM). It explains the contents of certificates of analysis for CRMs and product information documents for RMs, based on existing international standards and guides. It briefly touches on the minimum requirements for a label attached to the CRM/RM unit or unit container and to the package containing the unit or unit container.  
1.2 This guide provides some basic guidance on calculation of consensus values and uncertainty estimates for CRMs and RMs with examples of approaches commonly used by national metrology institutes and suggestions for sources of information.  
1.3 Units—The values stated in SI units are to be regarded as the standard, whenever applicable. Values can be traceable to other higher-order reference systems, including Rockwell Hardness, pH, and other systems defined by an international standard or peer-reviewed publication.

Standard Test Method for Column Percolation Extraction of Mine Rock by the Meteoric Water Mobility Procedure

SIGNIFICANCE AND USE
5.1 This test method is intended as a means for obtaining an extract from mine rock samples. The extract may be used to estimate the final pH and release of certain constituents of the test sample under the laboratory conditions described in this test method.  
5.2 The pH of the extraction fluid used in this test method should reflect the pH of precipitation in the geographic region in which the mine rock is being evaluated.  
5.3 This test method is designed to mobilize potential contaminants present in the solids, so that the resulting extract can be used to assess leachate that could potentially be produced from mine rock in the field.  
5.4 This test method has not been demonstrated to simulate actual site leaching conditions.  
5.5 This test method produces extracts that are amenable to the determination of both major and minor (trace) constituents. When minor constituents are being determined, it is especially important that precautions be taken in sample preservation, storage, and handling to avoid possible contamination of the extracts.  
5.6 This test method is a comparative method intended for use as a routine method for monitoring mine rock. It is assumed that all who use this method will be trained analysts capable of performing skillfully and safely. It is expected that work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E882.
SCOPE
1.1 This test method provides a procedure for the column percolation extraction of mine rock in order to determine the potential for dissolution and mobility of certain constituents by meteoric water.  
1.2 This test method is intended to describe the procedure for performing column percolation extractions only. It does not describe all types of sampling and analytical requirements that may be associated with its application.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
