Gemma Dove has specialized in the beneficiation of quarry mines and coal ash for the purposes of economic growth and reducing environmental impacts. With more than 10 years of working at the Minerals Research Lab, she is now focused on experimental design and exploratory testing using microscopy and analytical tools. She has degrees in both Engineering and Environmental Studies.
 
Gemma has experience with industrial minerals such as high-purity quartz, feldspar, mica, iron minerals, kyanite, spodumene (lithium), sphalerite (zinc), tin, pyrite, and gold-silver.  
 

 

Jonathan Simms, Research Specialist

jrsimms@ncsu.edu
 
Jonathan Simms oversees the project management and coordination of pilot plant and lab scale projects. He serves as the Environmental Health and Safety Coordinator for the Minerals Research Lab and ensures compliance to safety and fire inspections. He specializes in the beneficiation process of industrial minerals and mine tailings with emphasis on management and troubleshooting of environmental impacts and sustainability. Jonathan has a BS in Environmental Studies.  
 
Jonathan has experience in multiple facets of mineral processing but with special emphasis on pilot plant design, plant flotation processes, dense media separation and mineral separation science. His favorite minerals include Feldspars, Graphite, Kyanite, Micas, Phosphate, Spodumene, Sulphides, Quartz (High to Low Quality), and REE Ore.
