What is it called when you remove ore deep from within the earth?
hard rock mining, underground mining
How did placer mining hydraulics mining and hard rock mining different?
Placer mining involves extracting gold and other minerals from alluvial deposits using water to separate the valuable materials from sediments. Hydraulic mining, a subset of placer mining, utilizes high-pressure water jets to dislodge rock and soil, often causing environmental damage. In contrast, hard rock mining targets minerals embedded in solid rock, requiring drilling, blasting, and the use of heavy machinery for extraction. While placer and hydraulic mining primarily rely on water, hard rock mining focuses on extracting minerals from deeper geological formations.
How are placer mining hydraulic mining and hard-rock mining different?
Placer mining involves extracting minerals such as gold from riverbeds and alluvial deposits using techniques like panning and sluicing. Hydraulic mining involves using high-pressure jets of water to dislodge rock and sediment to extract minerals. Hard-rock mining involves underground excavation to extract minerals like gold, silver, and copper from solid rock deposits.
Why was mining for gold such hard work?
Mining for gold was very hard work. This was because gold usually came in very small pieces and was hard to extract from the rock it was imbedded in .
What are the two types of gold mining?
The two types of gold mining are placer mining and hard rock mining. Placer mining involves extracting gold from deposits of sand, gravel, and other sediments in rivers and streams. Hard rock mining involves extracting gold from underground ore bodies through drilling, blasting, and processing the ore.
How did placer mining hydraulic mining and hard rock mining differ?
Placer mining involves extracting minerals from loose materials like sand and gravel, usually done by panning or using sluices. Hydraulic mining involves using high-pressure water jets to dislodge materials, often causing environmental damage. Hard rock mining involves extracting minerals from solid rock formations, requiring more labor and machinery than placer mining.
How did placer mining hydraulic mining and hard-rock mining differ?
Placer mining involves extracting minerals like gold from deposits in rivers and streams using pans or sluice boxes. Hydraulic mining uses high-pressure jets of water to dislodge minerals from hillsides, causing significant environmental damage. Hard-rock mining involves extracting minerals from solid rock formations underground using drilling and blasting techniques.
What is rock mining?
Rock mining is when you get metal out of a rock.
