2020325There are four main mining methods underground open surface pit placer and insitu 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. Insitu mining
A renewable resource is a resource that can be replenished or replaced through biological reproduction or other natural processes. When energy is obtained from renewable resources the strain placed on the limited supply of nonrenewable resources is reduced.

The most common surface mining technique is openpit mining Figure 1 where a commodity is extracted via an open pit in the ground. This is an extremely cost effect way of removing a resource because large quantities can be removed with minimal effort. Other surface techniques include quarrying and strip mining.

Mining companies do not plan extraction further than about 30 years ahead so therefore the combined data from mining companies on reserves do not reflect the extractable global resources. The extractable global resources are represented by the righthand tails of the two graphs in Fig. 1. The socalled mineralogical barrier is the
