What factors did you consider in selecting where to start mining the rocks?

What factors did you consider in selecting where to start mining the rocks?

The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

How does mining have a harmful effect on the environment?

Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local …

How do geologists know where to mine for diamonds?

Although geologists now know where kimberlites are most likely to occur, they are usually covered below the Earth’s surface. Second, once a kimberlite is found, it must be sampled to determine if it contains any diamonds and if there are enough to support the development of an economically-viable mine.

What circumstances might a mineral deposit be an ore one day and not the next?

Because market factors change continually, a given mineral deposit may sometimes be an ore deposit, but at other times it may be uneconomic and hence not an ore deposit.

Why does mining have such an impact on the environment quizlet?

Mining has a large impact on the environment because minerals are contained within the Earth. Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.

What are the factors you have to consider before choosing any of the mining method?

Factors influencing mining method selection

  • Ore grade and recovery.
  • Cost of infrastructure.
  • Ore extraction.
  • Labour and machine costs.
  • Underground support costs.
  • Geotechnical factors.

Why has mining become a major environmental concern?

The extraction of minerals from nature often creates imbalances, which adversely affect the environment. The key environmental impacts of mining are on wildlife and fishery habitats, the water balance, local climates & the pattern of rainfall,sedimentation, the depletion of forests and the disruption of the ecology.

How does metal mining affect the environment?

Operations and waste products associated with metal extraction and processing are the principal causes of environmental concerns about metal mining. Concerns include: Physical disturbances to the landscape. Soil and water contamination.

Are diamonds easy to find?

Remember that diamonds are rare, even in low layers. It might take a long time for you to find any. And of course, there’s always a chance that you won’t find any at all before you need to head back home. But once you find diamond ore, mine it with the iron pickaxe and collect your prize.

Where do you find diamonds in real life?

South Africa, Russia and Botswana are the main producers of gem diamond while Australia produces most of the industrial diamond. They are also found in India, Russia, Siberia, Brazil, China, Canada and the United States.

What might cause a mineral deposit that had not been considered an ore to become reclassified as an ore?

What might cause a mineral deposit that had not been considered an ore to become reclassified as an ore? If demand for a metal increases and prices rise sufficiently, the status of a previously unprofitable deposit changes and it becomes an ore.

Why does mining have such an impact on the environment a mining only affects the living parts of the environment?

What was the purpose of the Red Bead Experiment?

The Red Bead Experiment is a training tool that Dr. Deming used to teach his 14 Obligations of Management. The exercise is used as a tool to bring people together and to get past the emotional aspects of discussing problems. Jim began the exercise by asking for four Willing Workers.

Is it possible to recover gold from pyritic sulfide?

The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology. That appears to leave froth flotation as still the best method of recovering the gold from pyritic ores.

How big are gold particles in pyritic sulfide ores?

If the assay is 2 ounces per ton, there are generally larger gold particles present along with the typically fine micron sized gold. When the grade diminishes to say, 0.2 ounces per ton, there are generally only micron sized particles associated with the pyrites in the ore.

When was the Red Bead Experiment at Michigan Tech?

On Tuesday, June 9th, Michigan Tech had the privilege of experiencing Dr. W. Edward Deming’s Red Bead Experiment which was presented by Michigan State University’s Jim Manley.
