Arsenic Stabilization Research Project
Principal Investigator: Dr. Larry Twidwell

This project developed a new, patentable technology to remove arsenic from waste streams to form a very stable compound. This project has solved the stability problem of current technologies used to remove arsenic. The technology developed in this project, unlike then-current ones, does not rely on adsorption, but rather compound formation. The apatite (Ca10(AsxPyO4)6(OH)2) compounds formed under this technology have a low solubility under typical tailings storage conditions, thus making this technology viable for many current mining operations.
