Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

A Brief Introduction to the Types of Surface Mining Methods

These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is the most widely used method in North America.

The Environmental Science of Surface Mining dummies

Placer mining. Placer mining is a way of obtaining mineral and metal resources from loose river sediments. The water helps sift the valuable resources (such as gemstones or gold) from the sand, mud, and gravel in the riverbed. Placer mining occurs on a much smaller scale than other methods of surface mining.
