A Brief Introduction to the Types of Surface Mining …

Open-pit Mining. Open-pit mining is a method in which an ore is removed by digging a pit in the ground, and is used to remove copper, gold, iron, as well as non-metallic minerals. It is normally used when the rock layer above the ore is too weak to allow underground tunnels. In this technique, circular steps, or ''benches'', are dug around ...

Silver Ore

 · Preparation of Silver Ore. The first stage of mining silver involves the crushing the silver ore to about 1-1.5in diameter so as to make the ore porous for the extraction process. Once the ore is crushed it is then mixed with lime (about 3-5 lb. per ton) to create a …

Selection of mining method

The selection of the mining method may also need to occur prior to the completion of desired geotechnical or ore value determinations. The Mining professional will need to continually debate if the information picture is complete enough for the design. In some cases the picture will only be more complete when mining has commenced.
