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.

consist of size reduction (or comminution) by crushing and grinding for the liberation of minerals, separation of mineral particles by va rious principles and a number of operations associated with them. However, most of the processes are basically physical (or mechanical), even if chemical effects may play important roles.
Cone, jaw, gyroscopic crushing etc. are the most common techniques for crushing where as grinding is usually performed by rod milling, ball milling etc. …

• Precision grinding (die grinders) • Rough grinding and cutting off • Surface grinding (sanders and polishers) With this division, distinctions are made regarding grinding purpose, tool types, abrasives (grinding wheels, etc.) and their attachments, settings (rotational speeds, etc.) and grinding tech- nique.
A mineral is a naturally occurring crystalline solid that cannot be physically broken down into smaller components.. Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. Magma is one such medium that transports ores. When magma or lava cools, the magma and ore carried within it crystallize to …
