Researchers at state universities in the Southeast are closing in on whether one of the region’s biggest liabilities – coal mine waste – might become a valuable asset by supplying rare earth elements needed for clean energy and other applications.

The answer lies in whether the University of Kentucky, Virginia Tech and West Virginia University, working with federal energy laboratories, a few coal companies and large manufacturers, can identify ways and locations to economically extract and process rare earth elements from the waste streams left over from mining coal throughout Appalachia and Western Kentucky.

“We’re working with members of the coal industry and state agencies that are engaged in treating AMD (acid mine drainage) solids to sample their waste streams, said Paul Ziemkiewicz, the lead researcher who heads the West Virginia University’s (WVU) research with colleagues Xingbo Liu and Aaron Noble at its Water Research Institute in Morgantown.

The collaborative effort faces its first key milestone this summer when it completes the first of two phases under $7 million of federal funding, said Roe-Hoan Yoon, the lead researcher at Virginia Tech in Blacksburg. The first $1 million is to produce a report summarizing their research findings to date.

Phase two, budgeted at $6 million, is to design a mobile pilot processing plant that could move among several sites, may be at risk if Congress does not pass a budget for the current or next fiscal year, which begins October 1. Yoon estimated the cost to build such a pilot facility at about $20 million.

“When you look at the list of what (REEs) we import, where we import it from, and what it is used for, it quickly becomes clear that we have a very real problem on our hands,” said Sen. Lisa Murkowski, chair of the Senate’s Energy and Natural Resources Committee hearing Tuesday. “If we let this go unchecked, we will come to a day of reckoning … when we simply cannot acquire a mineral, or when the market for a mineral changes so dramatically, that entire industries are affected.”

Ziemkiewicz analyzes data from untreated mine water used as a drinking source for Inside Appalachia

Written by Tracy Novak, NRCCE Communications on . Posted in Media, News

Morgantown, W.Va. – As mining companies close and leave Appalachia, water systems in these company towns are often abandoned. Eight water systems in southern West Virginia are “intractable,” meaning the systems are no longer maintained and the water is no longer treated, leaving residents vulnerable. In Garwood (Wyoming County), water comes from an abandoned coal mine.

Inside Appalachia, a program on West Virginia Public Broadcasting, examined the question, “Is water from an abandoned coal mine fit to drink?” Reporter Anne Li asked Paul Ziemkiewicz, director of the West Virginia Water Research Institute, to comment on water testing results from coal mine water that feeds into Garwood’s derelict water system.

With the limited data provided, according to Ziemkiewicz, the worst containment in the water from 2000 to 2008 was coliform. This bacteria can be a sign of sewage contaminating the water supply. Data from 2008 to 2014 showed no signs of coliform, but because the water is still untreated, Garwood has been on a boil water advisory since 2015.

WVWRI to co-host regional water conference; announces Call for Abstracts

Written by Andrew Stacy on . Posted in Blog, Events, News

The West Virginia Water Research Institute at West Virginia University is accepting abstracts through March 27 for the 2017 Mid-Atlantic Water Resources Conference.

The event will be held October 12-13, 2017 at the National Conservation Training Center in Shepherdstown, W.Va. “Water Research: Building Knowledge and Innovative Solutions” is the theme for this regional conference.

Researchers from colleges and universities, state and federal agencies, private organizations, consulting firms, industry and students are invited to submit abstracts for consideration for oral and poster presentations.

Abstracts for basic and applied research papers are being solicited in all areas related to water resources including infrastructure, energy, monitoring, policy, supply, technology, water quality and others.

The conference combines exceptional educational programs with opportunities for researchers, policy makers, state and federal agencies, environmental consultants, private organizations and the public to share in the latest information, technologies and research relating to water resources in the Mid-Atlantic.

“Water science, unlike many fields, involves a wide range of disciplines including law, engineering, social sciences, policy, economics, chemistry and biology,” said Paul Ziemkiewicz, director of the West Virginia Water Research Institute.

“This conference is a great opportunity to bring practitioners together to build the knowledge base needed to effectively manage our most precious resource.”

The event is being hosted by the West Virginia Water Research Institute, University of Delaware Water Resources Center, Pennsylvania Center for Water Resources Research at Pennsylvania State University, and the Virginia Water Resources Research Center at Virginia Tech.

WVU Study will Determine amount of rare earth elements in the region’s coal mining waste

MORGANTOWN, W.VA. –The U.S. Department of Energy’s (DOE) National Energy Technology Laboratory recently awarded West Virginia University (WVU) a project to survey acid mine drainage (AMD) solids to identify the concentration and amount of rare earth elements available in AMD solids.

The new project will sample and analyze AMD solids from 120 AMD treatment sites at coal mines across the northern and central Appalachian coal basins in West Virginia, Pennsylvania and Ohio. This follows a February 2016 NETL award to WVU to explore the potential to recover and extract rare earth elements from AMD solids, a project that is currently underway.

Acid mine drainage from pre-law coal mines is a major stream pollutant in the Appalachian region. However, when treated to meet current regulatory requirements, it yields solids that have proven enriched in critical rare earth elements.

“We will work with members of the coal industry and state agencies that are engaged in treating AMD to sample their solids” said Dr. Paul Ziemkiewicz, director of the West Virginia Water Research Institute and principal investigator on the project.

This new effort is in support of the DOE’s ongoing program to recover rare earth elements from coal and coal by-products.

Rare earth elements are vital to the technology industry. These elements have numerous applications and are used in devices such as cell phones, medical equipment and defense applications. Conventional rare earth recovery methods are difficult, expensive and generate large volumes of contaminated waste.
In addition to providing a domestic supply of these critical industrial materials, this approach would incentivize AMD treatment and offset treatment costs while continuing to improve the quality of Appalachian streams.

Appalachian coal mines commonly generate AMD, when sulfide minerals in rock are exposed to air and water. This acid leaches rare earths from coal associated rock where it collects as AMD. Active coal mines are required to treat this AMD, which concentrates and precipitates rare earth elements.

“Together, the rare earths in AMD solids range in value from $45 to $125/kg and our early sampling indicated that AMD solids contain between 0.3 and 1.5 kg of total rare earth elements per ton of AMD solid” said Ziemkiewicz.

Ziemkiewicz, along with co-investigators Xingbo Liu, professor of mechanical engineering, and Aaron Noble, professor of mining engineering, in the Statler College of Engineering and Mineral Resources will estimate the volume of acid mine drainage that is available in the northern and central Appalachian coalfields, as well as the purity and amount of rare earth elements that could be recovered. The research team will be assisted by Ben Faulkner, an independent contractor from Princeton, West Virginia, who has extensive experience with acid mine drainage treatment plants across the Appalachian region.

“Acid mine drainage solids are generated at treatment plants, and Ben’s familiarity with these facilities will be a tremendous asset to the project,” said Ziemkiewicz.
