Carlos and Kwon went to the Venetia Diamond Mine in South Africa to conduct a large-scale enhanced weathering experiment, testing depositions of fine kimberlite residues to optimize carbon removal. They also conducted a CO2 flux survey on the fine residue impoundments to identify optimal conditions for carbon removal under current deposition practices. Excellent work team! This research is part of Project CarbonVault with the goal of reducing the net greenhouse gas emissions at De Beers’ mines.
