Silica/fly ash-based technology for controlling pyrite oxidation. Semi-annual technical progress report, September 1, 1995--February 29, 1996

摘要

The overall objective is to develop methodologies by which sodium metasilicate or fly ash may produce an effective coating on pyrite surfaces for inhibiting pyrite oxidation. Accomplishments are described for the following tasks: Pyrite surface reactivity; Micro column leaching experiments; and Large column leaching experiments.
