Block caving: A new mining method arises | Geoengineer
The cost of block cave mining is about 1/10 of the correspondent cost of conventional methods. The production rates can reach 30,000 to 100,000 tons per day. Moreover, drilling and blasting costs are far less, and there are no backfilling costs. Another benefit of block caving is the large reduction in surface waste disposal needs.
How much CO2 is emitted by manufacturing batteries?
Currently, most lithium is extracted from hard rock mines or underground brine reservoirs, and much of the energy used to extract and process it comes from CO 2-emitting fossil fuels. Particularly in hard rock mining, for every tonne of mined lithium, 15 tonnes of CO 2 are emitted into the air. Battery materials come with other costs, too.
