Economic Geology Ore Grade

Ore grade shapes mining profits and environmental impact in unexpected ways

0

Why might a mining operation choose to extract ore with a lower grade instead of focusing solely on high-grade ore?

Because lower-grade ore always contains more valuable metals than high-grade ore. Because ore grade has no impact on mining costs or environmental considerations. Because lower-grade ore might be easier to access or process, making it economically viable despite lower concentration.

Economic Geology Mineral Deposit

The hidden wealth beneath our feet can transform entire regions overnight

0

What is the primary factor that determines whether a mineral deposit is economically viable to mine?

The total size of the mineral deposit regardless of mineral concentration The presence of any minerals, regardless of their economic value The concentration of valuable minerals relative to extraction costs (ore grade)

Economic Geology Gangue Assemblages in IOCG Deposits

Iron oxide gangue minerals reveal hidden pathways of precious metal formation

0

How do gangue assemblages in IOCG deposits influence mining strategies and exploration?

They are irrelevant to ore formation and only complicate mining without providing useful information. They indicate the hydrothermal processes and help identify ore zones, while their mineralogy affects ore processing methods. Gangue minerals are the primary source of copper and gold in IOCG deposits.

Economic Geology Ore Deposit

The true value of ore lies not just in its minerals but in the cost to extract them

0

What primarily determines whether a rock containing valuable minerals is classified as an ore deposit?

The total volume of the rock regardless of mineral concentration The concentration of valuable minerals relative to the cost of extraction The presence of any amount of valuable minerals without considering economic factors

Economic Geology Gold Deposits

Gold often hides alongside copper and iron oxides in rare, valuable ore deposits

0

What geological process primarily leads to the formation of Iron Oxide Copper Gold (IOCG) deposits?

Circulation of hydrothermal fluids depositing metals in iron oxide-rich rocks Volcanic eruptions directly depositing gold and copper on the surface Gold deposits forming exclusively in quartz veins without other metals

Economic Geology Orogenic Gold Deposits

Most of Earth's gold owes its existence to ancient mountain-building forces shaping hidden veins

0

What primarily controls the location and formation of orogenic gold deposits?

The structure of the rock, which guides mineral-rich fluids and deposition The amount of gold originally present in the Earth's mantle Random accumulation of gold particles in sedimentary basins
