PROCESS DESCRIPTION <br /> A lime hydroxide precipitation/dissolved air process is <br /> utilized to treat the Mt Emmons-Keystone Mine discharge water . <br /> The process produces a precipitate containing relatively high <br /> concentrations of metallic compounds . The precipitate is <br /> dewatered and chemically stabilized ( fixed) with Portland <br /> cement at the treatment facility . The resultant material is <br /> then transported , via commercial carrier , to the Climax Mine <br /> where it is off- loaded at the Clinton Cut-out access of the <br /> Mayflower Treatment Pond , and is subsequently assimilated into <br /> the Climax Mine Water Treatment precipitate (See attached map <br /> in Appendix "B") . Approximately 735 tons of fixed precipitate <br /> are processed and transported annually . <br /> CHEMICAL CHARACTERISTIC OF PRECIPITATE <br /> The precipitate metal assay and Toxic Characteristic Leaching <br /> Procedure (TCLP) data analysis result reports by the Hazen <br /> Researcn , Inc . laboratory , as presented in Appendix "A" <br /> (attached) , are typical . <br /> 4 - <br />
