Three methods of indigenous mining include panning for natural gold deposits in rivers and streams, using traditional pick and shovel techniques to extract minerals from small-scale surface mines, and using basic hand tools to dig tunnels into hillsides for underground mining operations.
The first methods of placer mining involved using simple tools like pans and sluice boxes to separate gold nuggets from sediment in rivers and streams. Miners would manually dig and sift through the sediment to find gold deposits. Over time, more advanced techniques like hydraulic mining and dredging were developed.
In the 1850s, gold mining equipment included pans, rockers (also known as cradles), long toms, sluice boxes, and hydraulic mining techniques like using hoses to wash away sediment. These tools enabled miners to extract gold from rivers, streams, and hillsides.
Stones are typically mined from quarries or obtained from rivers, beaches, and other natural sources. Mining operations or specialized stone extraction methods are used to extract stones from the earth's surface.

Large areas of land must be cleared for mining, and it causes pollution of rivers and soil.

Placer mining is recovering gold dust that has washed into streams and rivers (panning and sluice boxes, as well as dredges today) . Quartz mining involves traditional mining of gold bearing quartz rock, and requires digging,transporting, and crushing the rock to extract the gold.
Pollution from mining and drilling for oil pollutes the air, lakes and rivers

Coal mining can cause massive environmental destruction via unrestricted strip mining, and it can destroy nearby rivers via acid mine drainage. It can harm the health of workers and people living nearby, as well.
