Producing Environmentally Benign Materials from Mine Tailings using Hydrocarbon Polymerization
This invention is a way of making mine tailings more environmentally-friendly and efficient. The method stabilizes the mine tailings by creating a solid product of easily removable heavy metals that, in the event of failure, can devastate the surrounding environment if still present. This technology can be used in the nano-composite fabrication of hydrophobic,...
