Open-pit mining may cheaper when compared to other methods, but it is not environmentally-sound. "Open-pit mining clears the vegetation covering the deposits, exposing the soil and permanently changing the landscape and land use," said Dr. Daño, who was then the assistant director of the Ecosystems Research and Development …

2. The many ways mining activities impact biodiversity. Mining affects biodiversity at multiple spatial scales (site, landscape, regional and global) through direct (i.e. mineral extraction) and indirect processes (via industries supporting mining operations, and external stakeholders who gain access to biodiversity-rich areas as the result of mining).

Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.

The biggest advantage of open pit mining is the relatively low cost-extraction ratio. Open-pit mines are chosen when deposits of valuable minerals are found beneath the surface and where there overburden (overlaying rock or earth) is relatively thin. This means that no extensive tunnel network is required and no costly structural supports.

The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can sustain. There are many advantages in open-pit mining method namely:-Full visualization of exposed orebody and negligible ore loss,-

Open-pit Mining Methodology. Kagem is primarily an open-pit mine. One advantage of open-pit mining is that it makes every carat of emerald accessible. An underground operation requires leaving walls, ceilings, and pillars intact for shafts and tunnels, limiting or eliminating access to the emeralds in those areas.
