Successful gold mining is generally done in two steps First is sampling or prospecting, and then, production. While some goldbearing creeks and rivers tend to have gold values dispersed throughout their entire streambeds, there is generally not enough gold to make a smallscale mining operation payoff very well.
methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from lowgrade deposits by surface mining. Figure 1a. Production size distribution of metal mines for the period 1988 to 1997 in the CIVIL ENGINEERING Vol. II Surface Mining Methods and Equipment

Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from underground. See more detail on mining. 2. Crushing The primary crushers located at the open pit mine site, receive ore and waste at separate times.
Open pit mines can be used in coal mining, and they are used extensively in quot;hard rockquot; mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
