Pros and Cons
100

What is the first step in metal alloy manufacturing

First step is extracting raw ore from the ground

100

What are ferrous metals made of

Mostly made of iron

100

can recycled metal be repurposed?

YESSSSS

100
Do we recycle metal in New York City?

YASSSS

100

What is Aluminums melting point?

660 Degrees Celsius

200

What are the mineral rich deposits found within Earths crust called?

They are known as ores
200

examples of nonferrous metals

aluminum, copper, and lead

200

What is the acronym for the Electric Arc Furnance

EAF

200

Where does our NYC recycled metal end up?

Most of our cities metal ends up at Balcones Material Recovery Facility in Sunset Park, Brooklyn
200

what is a metal that is energy intensive to recycle?

Aluminum

300

What is slag

Slag is mainly a mixture of metal oxides and silicon dioxide

300

how are ferrous metals recycled

methods such as recasting, remelting, and redrawing within a steel mill

300

why would someone prefer to use recycled metal?

It is less expensive than metal derived from iron ore

300

Can we recycle Mercury?

NOOOOO

300

Name THREE Cons of "from scratch" metals

  • Mining for metal exploits finite resources and pollutes the environment

  • Metal production releases sulfur dioxide, nitrogen oxides, and CO2

  • Shaping and manufacturing metal requires a LOT of energy

  • Create waste like tailings and slag

  • Uses large amounts of water

400

What is the Electric Arc Furnace Method

The EAF method melts scraps using electric arcs which allow more efficient recycling of steel

400

What is scrap metal most often repurposed for?

most often used as fuel for electric furnaces

400

Give an example of a way recycled metal can be reused

An electric arc furnace can process scrap steel to increase its strength and durability

400

Can magnesium metal be recycled?

YES! It is considered one of the most eco friendly metals in the WORLD

400

Name THREE environmental benefit of recycling metal

  • reducing greenhouse gas emissions, conserving natural resources, and minimizing the amount of waste sent to landfills


    • we can save energy, reduce air pollution, and decrease water pollution

500

What is the Basic Oxygen Steelmaking method?

this method blows oxygen through molten iron to produce carbon and steel
500

How are nonferrous metals recycled?

These types of metals are thrown into reverberatory furnace

500

explain an electric arc furnace to the best of your ability

EAF- the metal is directly exposed to an electric arc, and the metal passes through the charge material

  • An electric arc is a breakdown of a gas that produces electric discharge between two electrode with a large heat by product

500

Name FOUR types of metals that can be recycled

  • Aluminum

  • Steel 

  • Copper

  • Brass

  • Bronz

  • Silver

  • Gold

500

Which metal produces the least amount greenhouse gases as of 1995-2015? *hint: chart*

LEAD, Zinc, and Tin (any counts)
