Basics of an open pit mine Mine
Open pit mines can be used in coal mining, and they are used extensively in quot;hard rockquot; mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Placer mining is very popular because: 1) of the low cost of this type of mining and 2) the fact that most of the gold can be recovered using lowtechnology (gravity) recovery methods. Open pit mining is popular for many of the same reasons.
Mining activities can be broadly divided in two types 1. Underground mining 2. Surface mining Now let''s talk about surface mining Depending on the topography, nature of the strata, working conditions, depth of the deposit and future use of the lan...
Placer Mining is a variety of openpit or opencast mining utilized to haul out minerals from the surface of the earth devoid of the usage of tunneling. Marine Mining: Marine mining method only became commercially feasible in the early 1990s. Marine diamond mining uses both quot;verticalquot; and quot;horizontalquot; methods to take out diamonds from offshore
underground mining as well as brief explanations of open pit, open cast, placer, and solution mining operations. Section 2 describe s surface mining equipmen t with particular focus on relatively large machines such as bucket wheel excavators, large shovels and draglines. 1. Surface Mining Methods
Openpit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling. Open pit mining is []

Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
Placer mining is the mining of alluvial sediments for minerals. This may be through by openpit (also known as opencast mining) or by a variety of forms of tunneling into antique riverbeds. Excavation might be achieved using water pressure (hydraulic mining), layer digging out equipment or tunneling equipment.
Openpit mining, or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Openpit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
