LEACHING BASALT ROCK USING AVERRHOA BILIMBI …
The high iron content in basalt rock needs to be reduced to obtain an appropriate acidity coefficient (Ka). One way is by leach-ing the basalt rock. Leaching is a solid-liquid extraction process. Liquid solid extraction is separating the solute contained in a solid by bringing the solid into contact with the sol-vent.

Enhanced Rock Weathering
Enhanced rock weathering is a strategy to help address climate change by taking carbon out of the air and storing it in rocks. It is one of several "carbon removal" techniques that target carbon dioxide (CO 2), the most important climate-warming greenhouse gas humans have been adding to the atmosphere.. Rocks and the natural …
