How Are Emeralds Mined?

The mining area is literally shaped like a pit that can hold equipment and workers Terrace Mining Terrace mining is similar to open-pit mining in that a large hole is dug as deep as 12 meters In the terrace-mining method, though, steps or "benches" are created parallel to the pit ,There are both open pit mining plant and underground mining equipment for magnesite in the world market Pillar mining system withuncemented backfilling is often used for magnesite mining operationThe main advantage of this mining method is the high flexibility for quality control.

Open Pit Mining Pros & Cons

An open pit mining operation virtually eliminates any biologic life at the surface Vegetation is stripped, and the surface at the dig site is left completely barren Without replanting and restoring the ecosystem, a strip mining site can take decades to recoverThe operation and management of a large open pit mine is an enormous and complex task, particularly for mines having a life of many years Optimization techniques can be successfully applied to resolve a number of important problems that arise in the planning and management of a mine.
