Larry Zanko, Sr. Research Fellow
Position and Focus
Larry Zanko is a Senior Research Fellow for the Economic Geology Program within the Minerals Division of the Center for Applied Research and Technology Development. He is a geological mining engineer and has been with NRRI since 1988. He has worked on a variety of research projects related to industrial, ferrous and nonferrous minerals. Areas of particular focus have included aggregates, biogeochemistry, geological data compilation, geostatistics, geological resource/mine modeling, environmental remediation, kaolin and ball clay evaluations, mining economics/tax comparisons and mineral waste characterization/utilization projects.

Utility of Taconite Materials as Road Patch for Highway Construction
To confirm the utility of using inorganically bound taconite aggregate and concentrate as highway road patching and construction materials.
Sediment for Biomass, Minnesota Mining Cluster - The Next Generation of Innovation
To conduct field trials of varieties of cellulosic feedstock on mineland tailings basins and other marginal lands using readily available soil amendment materials: clean sediments dredged from Duluth-Superior Harbor amended with treated municipal wastewater/biosolids. Objective is to conduct field-scale (>3 acres) research at one or more host taconite mines (or other brownfields/marginal lands location). Ultimate products will be: 1) identification of the most appropriate cellulosic feedstock species; 2) an assessment and proof-of-concept demonstration of overall waste and energy management planning and recycling in the region so long as sediment disposal challenges and mine land reclamation needs remain; and 3) energy development opportunity. Project findings would be applicable to other areas around MN and the Great Lakes region, including tailings basins, gravel pits, brownfields, and other marginal lands.
By-Product Aggregate, Minnesota Mining Cluster - The Next Generation of Innovation
To focus on implementation projects that introduce aggregate materials to targeted markets in project-sized quantities, value-added commercialization opportunities, and promising avenues of taconite-based applied research. Program includes: • Accelerated aggregate material qualification/certification program; • Development & deployment of mix and pavement designs using high quality taconite aggregate materials in their upper wear courses; • Production of value-added products from coarse taconite tailings, such as high friction bridge deck and airport runway surfacing aggregates; • Further development and implementation of innovative concepts, products and technologies such as: pothole/paving compounds and pursuing microwave-based technologies for all-season pothole and pavement repair; energy-absorbing materials for possible defense applications; UV, solar, and geothermal heating and energy storage. This project area is highly dependent on private sector and public sector interactions, negotiations, and timetables. Collaboration with private and public sectors at local, state, and national levels will be a key for implementing these activities and leveraging project resources.
Field Monitoring Atlas Brownfield Demo
NRRI and the U.S. Army Corps of Engineers (USACE) Engineer Research and Development Center (ERDC) in Vicksburg, Mississippi, are partnering to conduct a benefit analysis for using Erie Pier dredge material to passively mitigate pH at the former Atlas Cement site, located in Duluth near the St. Louis River and the Morgan Park neighborhood. The current project will focus on monitoring to measure the effects of buffering site pH and potential release of metals from site soil. Project results will be used as a guide for the potential use of Erie Pier dredge material at other brownfield sites.
Addition of Hibbing Taconite (Hibtac) Pilot-Scale Mine Land Demonstration Site For Application
To evaluate the use of dredge material from the Erie Pier facility in Duluth to restore vegetation at a degraded upland borrow pit site controlled by Hibbing Taconite (Hibtac). The upland site will also be used for monitoring growth of potential invasive species such as purple loosestrife, and for assessing best practice control measures. The pilot project will provide useful comparative information that could be applied to other mine land and marginal land restoration and reclamation applications.
