What are the main methods of mining? American

There are four main mining methods: underground, open surface (pit), placer, and in-situ 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.

Mining techniques for companies| surface, underground

Mining Techniques is divided into two types: surface mining and underground mining.Mining targets are divided into two categories of materials: placer deposits and lode deposits. If a mineral is stable chemically and is resistant physically, it can be eroded from its primary hard-rock occurrence and transported to river channels, deltas or other sedimentary environments where it can be

Mining : What is Mining? What are the 4 mining methods

Apr 28, 2019· Mining techniques. Surface mining. Surface mining is done by removing (stripping) surface vegetation, dirt, and, if necessary, layers of bedrock in order to reach buried ore deposits. Techniques of surface mining include: open-pit mining, which is the recovery of materials from an open pit in the ground, quarrying, identical to open-pit mining

Underground mining (hard rock) Wikipedia

Selective mining methods. Cut and fill mining is a method of short-hole mining used in steeply dipping or irregular ore zones, in particular where the hanging wall limits the use of long-hole methods. The ore is mined in horizontal or slightly inclined slices, and then filled with waste rock, sand or tailings

Mining Methods Boxhole Boring. Boxhole boring is similar to the raisebore method, but the drilling machine is located below the mineralization, so development is not required above the mineralization.From a drill chamber in waste rock below the ore, we drill a series of overlapping holes up through the ore zone and collect the falling ore from a chute in the extraction chamber.
