How Do We Extract Minerals Usgs
The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock. Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods.

Enhanced Weathering The Future Forest Company
Rock weathering is a core part of the global carbon cycle where CO2 in rainwater reacts with rocks and is then locked away in carbonate form for over 100,000 years. By crushing up rock into rock dust, you increase its surface area. The weathering process therefore happens faster, so CO2 is taken out of the atmosphere faster.
