What’s on the Extracting Metals poster
A 4-row table: Metal · Method.
Extraction method by position in the reactivity series.
- K, Na, Ca, Mg, Al — Electrolysis of molten ore
- Zn, Fe, Sn, Pb — Reduction with carbon
- Cu — Reduction, then electrolytic refining
- Ag, Au, Pt — Found native; physical separation
Aluminium requires electrolysis and cryolite to lower the melting point of alumina from 2072°C to around 950°C.
Questions about the Extracting Metals poster
- What’s on the Extracting Metals poster?
- A 4-row table: Metal · Method. Extraction method by position in the reactivity series. K, Na, Ca, Mg, Al — Electrolysis of molten ore; Zn, Fe, Sn, Pb — Reduction with carbon; Cu — Reduction, then electrolytic refining; Ag, Au, Pt — Found native; physical separation. Aluminium requires electrolysis and cryolite to lower the melting point of alumina from 2072°C to around 950°C.
- Who is the Extracting Metals poster for?
- Extracting Metals belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning inorganic can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Extracting Metals poster?
- More reactive metals need electrolysis. Less reactive ones can be reduced with carbon. A wall chart earns its place by being glanceable from where the work is happening, so Extracting Metals belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Extracting Metals?
- Catalysts, Complex Ions and Electrolysis sit alongside Extracting Metals in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.CatalystsComplex IonsElectrolysis
- Is the Extracting Metals poster free to download and print?
- Yes. Extracting Metals downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Extracting Metals poster print at?
- Extracting Metals is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Extracting Metals loses nothing.Printing guide
