New publication: Weathering and cementation of historic kimberlite residues from South Africa: Implications for residue stabilization and CO2 sequestration. Graduate student Justin Lockhart investigated historic mine wastes at the Cullinan and Voorspoed diamond mines in South Africa to better understand how these mine wastes weather, cement, and potentially mineralize CO2. This research has implications for the long-term disposal of alkaline mine wastes, their stabilization, and ability to sequester CO2 over decades post-mining. Congratulations Justin on an outstanding publication!
