|---|---|---|---|---|---|
| What is an alloy? | A mixture of metals (and sometimes non-metals) e.g. Brass is a mixture of copper and zinc.
🗑
|
||||
| What is brass? | An alloy of copper and zinc.
🗑
|
||||
| Describe the properties of aluminium and what it is use for. | A low density, corrosion resistant metal use in many alloys, including those used in the aircraft industry.
🗑
|
||||
| What is bioleaching? | The process of extracting metals from low grade ores using micro-organisms.
🗑
|
||||
| What is a blast furnace used for? | The blast furnace is the huge reaction vessel used in industry to remove iron from it’s ore.
🗑
|
||||
| What is carbon steel? | Alloy of iron containing small, controlled amounts, of carbon.
🗑
|
||||
| What is cast iron? | The impure iron taken directly from the blast furnace.
🗑
|
||||
| What is a copper rich ore? | A rock that contains a high proportion of a copper compound.
🗑
|
||||
| What is a high-alloy steel? | An expensive alloy of iron mixed with relatively high proportions of other metals e.g. stainless steel which contains nickel and chromium along with the iron.
🗑
|
||||
| What is a low-alloy steel? | An alloy of iron containing small amounts (1-5%) of other metals.
🗑
|
||||
| What is an ore? | A rock which contains enough metal to make it economically viable to extract the metal.
🗑
|
||||
| What is oxidation? | A reaction when oxygen is added to a substance (or electrons are lost)
🗑
|
||||
| What is phytomining? | The process of extracting metals from low grade ores using plants.
🗑
|

🗑
|
||||
| What is the process by which one element takes the place of another, less reactive element? | Displacment/Displace.
🗑
|
||||
| What is meant by “displace”? | When one element takes the place of another in a compound. For example iron + copper sulphate = iron sulphate + copper.
🗑
|
||||
| What is reduction? | A reaction in which oxygen is removed (or electrons gained).
🗑
|
||||
| What is a shape metal alloy? | A mixture of metals which responds to changes in temperature?
🗑
|
||||
| What is smelting? | Heating a metal ore in order to extract its metal.
🗑
|
||||
| What is stainless steel? | A chromium/ nickel alloy of iron which does not rust.
🗑
|
||||
| What is steel? | An alloy of iron with small amounts of carbon or other metals, such as nickel or chromium, added.
🗑
|
||||
| What is titanium? | A shiny, corrosion resistant, metal used to make alloys.
🗑
