NE WMON T Newmont Mining Corporation <br /> Metallurgical Services <br /> 10101 East Dry Creek Road <br /> Englewood,Colorado 80112 <br /> www.newmont.com <br /> STANDARD OPERATING PROCEDURE <br /> Method: SWDC— Modified TCLP Extraction for Solid Waste Characterization <br /> Date: August, 1th 2011 <br /> SOP#: NMS-ANA-SOP-SWDC <br /> Revision #: 1.0 <br /> Revised by: David Tryon, Metallurgical Technician II <br /> Effective Date: October 11 th 2012 <br /> Authorized By: J.M. Lorengo, QA/QC Engineer <br /> 1. SCOPE AND APPLICATION <br /> 1.1 The SWDC test is intended to reflect the interaction of the leach solution and <br /> buffering capacity of the waste. It is applicable for single batch extractions only. It <br /> does not apply to organic substances, volatile matter or biologically active samples. <br /> This test is similar to EPA Method 1311 test but is informational only and not <br /> intended for regulated purposes. <br /> 2. SUMMARY OF METHOD <br /> 2.1 The SWDC method calls for the shaking of a known weight of mining waste with <br /> extraction fluid of a specified composition, as well as the separation of the <br /> liquid phase for analysis. The final leachate is filtered, the pH measured, and <br /> finally submitted for analysis. <br /> 3. INTERFERENCES <br /> N/A <br /> 4. SAFETY <br /> 4.1 This method involves the use of concentrated acids and mechanical hazards. <br /> Concentrated nitric acid is highly corrosive and a strong oxidizer. Anhydrous <br /> acetic acid is highly corrosive. Avoid lose clothing and tie up hair around the <br /> bottle rolls to keep from being pulled in. All processes should be carried out <br /> wearing safety glasses, protective gloves and a lab coat. As with all tests, the <br /> primary responsibility for safety lies with the analyst. Please consult the <br /> appropriate MSDS and the Newmont Chemical Hygiene plan for further details. <br /> Plato Malozemoff Technical Facility I Newmont Metallurgical Services <br /> The information contained in this report is confidential and proprietary. 1 <br />
