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.
By-Product Aggregate, Minnesota Mining Cluster - The Next Generation of Innovation
The program will focus on near-term 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. The program includes:
• An 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; and UV, solar, and geothermal heating and energy storage. This project area is highly dependent on private sector/private sector and private sector/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.
Erie Pier Dredged Material Beneficial Use Study
(1) Identify landowners willing to participate in demonstration projects and receive fine grained dredged material for restoration demonstrations.
(2) Evaluate the cost and feasibility of using rail transportation to move Erie Pier fine grained dredged material to potential recipient sites.
(3) Provide monitoring and results analysis of vegetative health, plant diversity and control of purple loosestrife for demonstration sites.
(4) Evaluate the effectiveness of using microwave technology to sterilize seeds contained in Erie Pier fine grained dredged material.
(5) Conduct a laboratory and field assessment of the stamp sand area near Gay, Michigan, within the context of this location being a potential recipient site for navigation channel material from the Duluth-Superior harbor and/or Erie Pier for establishing stamp sand-stabilizing vegetative cover.
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. The 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 Minnesota and the Great Lakes region, including tailings basins, gravel pits, brownfields, and other marginal lands.
