<br />2.0 TAILINGS LIQUOR SAMPLES <br />~ ~440~~SAMPLE TO BE TESTED: L396.4 - 2.0 TL <br />Test this sample (dissolved basis) for the following D~arameters: <br />pH, Conductivity, Hajor Cations (Calcium, Magnesium;) Potassium, <br />Sodium), Major Anions (Alkalinity, Ammonia, Bicarbonate, Carbonate, <br />Chloride, Fluoride, Hydrogen Sulfide, Nitrate, Nitrite, Sul ate). Total <br />Dissolved Solids, Total, Free and A.A.D. Cyanide, plus tt~e following <br />dissolved metals: <br />Aluminum, Arsenic, Barium, Boron, Cadmium, Chrom#um (total), <br />Copper, Iron, Lead, Manganese, Mercury, Molybdequm, Nickel. <br />Selenium, Silver, Zinc. <br />• <br />3.0 TAILINGS SOLIDS SAMPLE <br />3.1 SAMPLE PREPARATION: <br />.~ <br />~\yau SAMPLE TO BE TESTED: L396.4 - 2.0 S <br />cb <br />These solids should be split into two specimens. one specimen should <br />be tested as is and will represent unleached tailings conditiPns. Pleasa <br />label this sample L346.4 - 2.0 S. bq\~~o.~'~ <br />The second specimen should be labeled L)96.4 - 2.1 S. Th s specimen <br />should be rinsed with DI xater (adjusted to a pH of 5.0 - 5. no less <br />then 5.0). Rinsing shall be accomplished by mixing at about~a 10 to 1 <br />ratio (liquid to solids) is a closed container with zero head pace or an <br />inert gas head space (argon gas). Allow the solution to quilibrate <br />overnight. Decant the leachate and test it for pH and Conductiv ty. Please <br />track all quantities of solids and leachate. <br />Continue this rinsing procedure until the DH of the leachate has gone <br />acidic or has stabilized for at least three leaching cycles. <br />3.2 APP/ANP TESTING: <br />SAMPLES TO BE TESTED: L396.d - 2.0 S; L396.4 - 2.1 S <br />Obtain sub-specimens of both tailings specimens (1 ached and <br />unleached) and air dry the material far Acid/Base Accoun inq. Test <br />the material at it's original grain size. Determine Total Sulfuc by <br />both Leco Furnace and Peroxide oxidization methods. Alsodetermine <br />Pyritic and Sulfate Sulfur as well as the Neutralizing Fbbtential. <br />• <br />
