Designation:D815517Standard Practice forShake Extraction of Solid Mining and MetallurgicalProcessing Waste with Water1This standard is issued under the fixed designation D8155;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers a procedure for leaching of solidwaste to obtain an aqueous solution to be used to determine theconstituents leached under the specified testing conditions.1.1.1 This practice includes a procedure for the shakeleaching of metal mining ore,waste rock,or metallurgicalprocessing waste containing at least 80%dry solids(20%moisture)in order to generate a solution to be used todetermine the inorganic constituents leached under the speci-fied testing conditions and for regulatory jurisdictions requiringa water leach practice.1.2 This practice provides for the shaking of a known massof waste with water of specified composition and the separationof the aqueous phase for analysis.1.2.1 This practice is intended to describe the procedure forperforming single-batch extractions only.It does not describeall types of sampling,sample preservation,and analyticalrequirements that may be associated with its application.1.3 The values stated in SI units are to be regarded asstandard.Values given in parentheses are mathematical con-versions to inch-pound units that are provided for informationonly and are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C471M Test Methods for ChemicalAnalysis of Gypsum andGypsum Products(Metric)D75/D75M Practice for Sampling AggregatesD420 Guide to Site Characterization for Engineering Designand Construction Purposes(Withdrawn 2011)3D1193 Specification for Reagent WaterD2216 Test Methods for Laboratory Determination of Water(Moisture)Content of Soil and Rock by MassD2234/D2234M Practice for Collection of a Gross Sampleof CoalD3370 Practices for Sampling Water from Closed ConduitsD5681 Terminology for Waste and Waste ManagementD5744 Test Method for Laboratory Weathering of SolidMaterials Using a Humidity CellD6234 Test Method for Shake Extraction of Mining Wasteby the Synthetic Precipitation Leaching ProcedureE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or ProcessE877 Practice for Sampling and Sample Preparation of IronOres and Related Materials for Determination of Chemi-cal Composition and Physical PropertiesE1915 Test Methods forAnalysis of Metal Bearing Ores andRelated Materials for Carbon,Sulfur,and Acid-BaseCharacteristicsE2242 Test Method for Column Percolation Extraction ofMine Rock by the Meteoric Water Mobility Procedure3.Terminology3.1 For definitions of terms used in this practice,seeTerminology D5681.3.2 Definitions of Terms Specific to This Standard:3.2.1 metal mining waste,noverburden or waste rockexcavated and disposed of during mining operations.1This practice is under the jurisdiction of ASTM Committee D34 on WasteManagement and is the direct responsibility of Subcommittee D34.01.04 on WasteLeaching Techniques.Current edition approved Dec.15,2017.Published December 2017.Originallyapproved in 2017.DOI:10.1520/D8155-17.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.2.2 mineral processing waste,nwaste generated fromore processing metallurgical operation such as tailings.4.Significance and Use4.1 This practice is intended as a rapid means for obtainingan extract of solid waste.The extract may be used to estimateth
