Types of Processes Mineral Production Activities
Placer Mining is the extraction of alluvial mineral deposits, either in pits or in river beds. It is usually applied to heavy minerals including gold, other metals and gemstones. Techn iques range from panning, in the ASM sector, to hydraulicking where high-pressure water jets, called monitors, fed by pumps, are used to excavate and transport

Modern mining SlideShare
Dec 05, 2015· 4. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. Mining techniques can be divided into two common excavation types: surface mining and sub- surface (underground) mining.

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

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.
