(Practice)Standard Practice for Shake Extraction of Solid Mining and Metallurgical Processing Waste with Water
Standard Practice for Shake Extraction of Solid Mining and Metallurgical Processing Waste with Water
SIGNIFICANCE AND USE
4.1 This practice is intended as a rapid means for obtaining an extract of solid waste. The extract may be used to estimate the release of constituents of the solid waste under the laboratory conditions described in this procedure.
4.1.1 This practice is not intended to be used as a kinetic test to simulate weathering of ore, metal mining, and metallurgical processing wastes. For kinetic testing of ore, metal mining, and metallurgical processing wastes, refer to Test Method D5744 to determine release rates for constituents of interest. For static testing of metal mining ore and metal mining or metallurgical processing waste materials, refer to Test Methods E1915 and D6234. If the conditions of this practice are not suitable for the test material, Test Method E2242 may be used, if applicable to the ore or waste.
4.2 This practice is not intended to provide an extract that is representative of the actual leachate produced from a solid waste in the field, or to produce extracts to be used as the sole basis of engineering design.
4.3 This practice is not intended to simulate site-specific leaching conditions. It has not been demonstrated to simulate actual disposal site leaching conditions.
4.4 The intent of this practice is that the final pH of the extract reflects the interaction of the extractant with the buffering capacity of the solid waste.
4.5 The intent of this practice is that the water extraction simulates conditions where the solid waste is the dominant factor in determining the pH of the extract.
4.6 The practice produces an extract that is amenable to the determination of both major and minor constituents. When minor constituents are being determined, it is especially important that precautions are taken in sample storage and handling to avoid possible contamination of the samples.
4.6.1 This practice has been tested to determine its applicability to certain inorganic components in metal mining and metallurgical processing wastes.

SCOPE
1.1 This practice covers a procedure for leaching of solid waste to obtain an aqueous solution to be used to determine the constituents leached under the specified testing conditions.
1.1.1 This practice includes a procedure for the shake leaching of metal mining ore, waste rock, or metallurgical processing waste containing at least 80 % dry solids (≤20 % moisture) in order to generate a solution to be used to determine the inorganic constituents leached under the specified testing conditions and for regulatory jurisdictions requiring a water leach practice.
1.2 This practice provides for the shaking of a known mass of waste with water of specified composition and the separation of the aqueous phase for analysis.
1.2.1 This practice is intended to describe the procedure for performing single-batch extractions only. It does not describe all types of sampling, sample preservation, and analytical requirements that may be associated with its application.
1.3 The values stated in SI units are to be regarded as standard. Values given in parentheses are mathematical conversions to inch-pound units that 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.
