Open pit mining is one of mankind''s greatest achievements in the ongoing search for precious ores such as copper, silver, iron, and gold. It describes the process of systematically excavating land and digging out the rocks and minerals in search of metallic ores and removing them via borrow or open pit.

Get PriceGet QuoteOpen pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

This mineral may be present in very low concentrations, in relation to the amount of material removed.
Get PriceGet QuoteAdvantages and disadvantages of open pit mining. Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or delicate, so that underground mining is not possible. Labor costs are lower, both in excavation and transportation, and allow the use of large machinery .

The conventional open-pit mining method comprising blasting and excavation is used at the Kombat copper project’s open-pit operation. The mining equipment includes excavators, dump trucks, haul trucks, and dozers. Underground mining is planned to be started in 2024.
Get PriceGet QuoteUnderground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world''s largest underground copper mine. Open pit mining is employed when the orebodies are extensive, low in grade, and relatively near the surface, where they can be quarried after removal of overburden.
Get PriceGet QuoteOpen-pit mining is to be considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners health, as well as damage to the ecological land. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths.
