PMY121 Engineering Test Week Revision

Mining geology is the study of the (fill in the blank), and includes classifying and
mapping of the composition and distribution of mineral deposits contained in the
earth's formations.

Those ores of the ferrous metals ( e.g. Iron, Manganese, Molybdenum and
tungsten), base metals (e.g. copper, lead, zinc, and tin), precious metals (gold, silver, the
platinum group metals (PGMs)) and radio active minerals such as uranium, thorium and
radium.

• Metallic ores

• Non-metallic ores

• fossil fuels

(also known as industrial minerals). They represent the non-fuel
mineral ores that are not associated with the production of metals. These include minerals
such as phosphate, potash, halite, trona, sand, gravel, limestone, sulphur and etc

• metallic ores

• non-metallic ores

• fossil fuels

(also known as mineral fuels). They represent organic mineral substances
that can be utilised as fuels e.g. petroleum, coal, natural gas, coalbed methane, gilsonite
and tar sands.

• metallic ores

• non-metallic ores

• fossil fuels

True or false: An ore is a naturally occurring material from which a mineral or
minerals of economic value can be extracted at a profit

• True

• False

True or false: indirect prospecting is limited to surface deposits, involves visual examination
of either the outcrop of the deposit or loose fragments that have been
weathered from the original outcrop.

• True

• False

True or false: Indirect prospecting is the most valuable tool employed to mineral
deposits hidden below the surface of the earth.

• True

• False

A mining geologist is:

• Involved in the mine planning process

• activities inclue mapping, recording and compiling
  geological data

• delineates the ore reserves on which the mine's life
  depends

• to predict the grade and structure
  of ore bodies

• All of the above

Strip mining is:

• applicable where the surface of the ground and orebody are relatively horizontal

• the orebody and surface of the ground are not too deep

• a wide area of surface ground and orebody are available

• mainly used for coal and other bedded deposit

• All of the above

What is open-pit mining?
