- The overall objective of this project is to develop methodologies by which sodium metasilicate or fly ash may produce an effective coating on pyrite surfaces for inhibiting pyrite oxidation. Milestones for the following periods include: First six-months - (1) Characterize pyrite surface reactions for understanding pyrite coating establishment. (2) Start a preliminary outdoor leaching - column experiment using 10 kg mine pyritic spoil treated with silicates to evaluate potential application of coatings on a large scale. Second six-months - (1) Characterize silicate - iron reactions in solution and on pyrite surface for understanding pyrite silica - coating formation. Third six-months - (1) Evaluate pyrite surface deposition of silicate having Na - silicate or fly ash as source. Fourth six- months - (1) Evaluate silicate coating durability in large outdoor columns.
