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.

Lapidary Fundamentals Cutting Rough Stones

Although hammering rough doesn't allow precise control over the size pieces you get, it's much more accurate than the drop-it-off-a-cliff method. If the rock you're working on has a fracture, you can usually break it along that line. Cutting a Kerf. Cutting a kerf in the stone will give you greater control.
