EnvSci Coal Mining Test

by using water to float the coal

How do miners mechanically seperate coal from rock?

Bituminous

The most common type of coal found in Ohio would be

Acid Rain due to the release of sulfur into the atmosphere and Global Warming due to the release of carbon dioxide into the atmosphere

Consequences of burning coal would include

Generation of Electricity

Primary uses of coal in the United States include

It contains the greatest amount of sulfur

Lignite coal is the least desirable coal because

Dead plants

Coal formation is the result of ______________ from the carboniferous period

Acid mine drainage (formation of sulfuric acid)

When water runs through spoil piles containing sulfur you could reasonably expect

Surface mining

The existence of Big Musky (large coal shovel) in Ohio is evidence of

Carbon

The main element making up coal is

exposing the rock to an acid solution

If you wanted to chemically extract a heavy metal from rock you could try

extraction of rock, mineral processing, metal purification, reclamation

Which of these are in the correct order of the mining process

extract the metal from the rock by dissolving copper into a solution

The purpose of using an acid during the copper mining lab was to

subsurface mining

extracting minerals, metals, or ores from deep beneath the ground using tunnels and shafts

turbine

Structure that turns large magnets and or copper coils to generate electricity

spoil piles

Piles of waste material removed when mining for a resource

reclamation

Process of restoring or repurposing land after a mining exploration is completed

smelting

Process of heating an ore or rock in order to extract the metal trapped inside

surface mining

extracting minerals, metals or ores from the ground using open pit or strip mining techniques

ore

a rock that contains a useful mineral or resource

acid mine drainage

water that has a low pH due to spoil piles, tailing piles or contact with chemicals released or exposed in the mining process

a process in which mined land must be recovered with soil and replanted with vegetation

Process of reclamation
