· Why Drone Technology Is the New Best Practice in Open-Pit Mining. Aerial images captured by drones are able to produce the most accurate site models to-date, which is important for two reasons: This allows mining operators to precisely calculate the amount of material that can be extracted, and quickly determine what equipment is best used for ...
Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.

· 1.What is open pit mining? Open pit mining is the process of removing the covering from the ore body to obtain the desired minerals. Open-pit mining can be divided into open-pit metal deposit mining, open-pit coal mining, and open-pit iron mining.The former mainly mines non-ferrous metals, the middle mainly mines coal and some non-metallic …
· In metal open-pit mine, the ore loss rate is generally 3% ~ 5% and dilution rate is generally 5% ~ 8%. While in underground mining, the ore loss rate is generally 15% ~ 25% and dilution rate is 3% ~ 20%. Therefore, open pit mining is beneficial to the full recovery of mineral resources. Especially for some high-temperature, flammable and watery ...
