Title Utilization of a ceramic membrane for acid mine drainage treatment Type Journal Article
Year 1997 Publication (up) Tailings and Mine Waste '97 Abbreviated Journal
Volume Issue Pages 453-460
Keywords acid mine drainage; Black Hawk Colorado; Central City Colorado; ceramic materials; Colorado; cost; disposal barriers; geochemistry; Gilpin County Colorado; heavy metals; mines; organic compounds; pollution; remediation; surface water; tailings; United States; utilization; volatile organic compounds; volatiles; waste disposal mine water treatment
Abstract BASX Systems LLC has developed a treatment system based on ceramic membranes for the removal of heavy metals from an acid mine drainage stream. This stream also contained volatile organic compounds that were required to be removed prior to discharge to a Colorado mountain stream. The removal of heavy metals was greater than 99% in most cases. A decrease of 30% in chemicals required for treatment and a reduction by more than 75% in labor over a competing technology were achieved. These decreases were obtained for operating temperatures of less than 5 degrees C. This system of ceramic microfiltration is capable of treating many different types of acid mine waste streams for heavy metals removal.

Title Environmental considerations of active and abandoned mine lands: lessons from Summitville, Colorado Type Journal Article
Year 1995 Publication (up) US Geological Survey Bulletin Abbreviated Journal
Volume 2220 Issue 38 Pages
Keywords acid mine drainage mining environmental effect remediation environmental assessment USA Colorado Summitville 1 Geography
Abstract Extreme acid-rock drainage is the dominant long-term environmental concern at the Summitville mine and could have been predicted given the geological characteristics of the deposit. Extensive remedial efforts are required to isolate both unweathered sulfides and soluble metal salts in the open-pit area and mine-waste piles from weathering and dissolution. Results of studies as of late 1993 indicate that mining at Summitville has had no discernible short-term adverse effects on barley or alfalfa crops irrigated with Alamosa River water. Remediation of the site will help to ensure that no adverse effects occur over the longer term. -from Editor

Title Experimental diversion of acid mine drainage and the effects on a headwater stream Type Journal Article
Year 1999 Publication (up) Water-Resources Investigations Report Abbreviated Journal
Volume Wri 99-4018-A Issue Pages 123-130
Keywords abandoned mines acid mine drainage algae benthonic taxa biomass biota Colorado experimental studies heavy metals Lake County Colorado Leadville Colorado metals mines pH Plantae pollution remediation Saint Kevin Gulch Colorado tracers United States USGS water zinc
Abstract An experimental diversion of acid mine drainage was set up near an abandoned mine in Saint Kevin Gulch, Colorado. A mass-balance approach using natural tracers was used to estimate flows into Saint Kevin Gulch. The diversion system collected about 85 percent of the mine water during its first year of operation (1994). In the first 2 months after the diversion, benthic algae in an experimental reach (stream reach around which mine drainage was diverted) became more abundant as water quality improved (increase in pH, decrease in zinc concentrations) and substrate quality changed (decrease in rate of metal hydroxide deposition). Further increases in pH to levels above 4.6, however, led to lower algal biomass in subsequent years (1995-97). An increase in deposition of aluminum precipitates at pH greater than 4.6 may account for the suppression of algal biomass. The pH in the experimental reach was lower in 1998 and algal biomass increased. Mine drainage presents a complex, interactive set of stresses on stream ecosystems. These interactions need to be considered in remediation goals and plans.
