Rock Crushing methods and How to recover gold from Ores
Finally, once the rock is fully crushed we get to the part about separating out the gold from the crushed rock. Often, this is accomplished simply by very careful panning. Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds. On the other hand if you are going to be processing large quantities

Everything You Need to Identify Rocks
In simple terms, hard rock scratches glass and steel, usually signifying the minerals quartz or feldspar, which has a Mohs hardness of 6 or higher. Soft rock does not scratch steel but will scratch fingernails (Mohs scale of 3 to 5.5), while very soft rock won''t even scratch fingernails (Mohs scale of 1 to 2).

Examples of Erosion
As waves crash into land on the shore, the sand, rocks, cliffs or soil along the shoreline gets eroded. Increases in sediment in the water greatly amplifies the impact of coastal erosion. cracks in shoreline cliffs due to joint compression via wave action; waves pounding on rocky shoreline breaks off chunks of rock

Weathering and erosion | Earth processes | OneGeology Kids
Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering. Water gets into cracks and joints in bedrock.

Rock Type: sedimentary Composition: grains of sand that can be feldspar or quartz
Limpets can be found specifically on intertidal rocks. This means the rocks are in an area where low and high tides reach it. There are periods that the rocks are submerged and periods where it is dried out because the tide is too low. Limpets are found on these rocks because they are best suited to rocks that aren’t going to wash out to sea.
