One way to mine emeralds is through the open-pit method. Workers dig a large pit of about 12 meters deep and then blast the surface with water to disclose the mineral-bearing rocks. In the open-pit mining method, a lot of waste rock must be moved away. The mining area is literally shaped like a pit that can hold equipment and workers.

 · Seismic Method. Surface seismic techniques used in gold exploration are restricted to seismic refraction and seismic reflection methods. Probably, the first one is the most employed. The equipment employed for both techniques is very similar and assure the travel time of acoustic waves propagating through the subsurface.

Mineral & Ore Processing. Ore processing is a chain of processing applications which treats run of mine to firstly high-grade concentrate (concentration of ores) and then to the pure mineral or metal. The refined ore is used in manufacturing equipment and machinery in numerous industries, or is for sale in industry, commerce and consumer ...

Placer mining is used to recover valuable minerals from sediments in present-day river channels, beach sands, or ancient stream deposits. More than half of the world''s titanium comes from placer mining of beach dunes and sands. In placer operations, the mined material is washed and sluiced to concentrate the heavier minerals.

Describe some of the extraction methods and identify different types of mining. In order to use the resources at our disposal, we need to be able to get to them. This section introduces the different techniques used to extract or remove these resources.
