Question 1 · 1 mark · Difficulty 1/3

Which metal is extracted from its ore by electrolysis rather than by reduction with carbon?

  1. D. Zinc, because its ore cannot be heated strongly enough
  2. A. Iron, because it is too reactive for carbon reduction
  3. C. Aluminium, because it is more reactive than carbon
  4. B. Copper, because it forms a stable oxide with carbon
Show answer & explanation
✓ Answer: C — C. Aluminium, because it is more reactive than carbon
Aluminium is more reactive than carbon, so carbon cannot reduce aluminium oxide; electrolysis of molten aluminium oxide is used instead. Iron is less reactive than carbon and IS extracted by carbon reduction in the blast furnace. Copper is less reactive than carbon and can be obtained by reduction or displacement. Zinc is less reactive than carbon and is extracted by heating its ore with carbon.
Question 2 · 1 mark · Difficulty 1/3

Which ore is the main source of aluminium used in industrial extraction?

  1. B. Bauxite, which contains hydrated aluminium oxide
  2. D. Galena, which contains aluminium sulfide
  3. C. Malachite, which contains aluminium carbonate
  4. A. Haematite, which contains aluminium silicate
Show answer & explanation
✓ Answer: A — B. Bauxite, which contains hydrated aluminium oxide
Bauxite is the principal ore of aluminium; it contains hydrated aluminium oxide (Al₂O₃·nH₂O) which is purified before electrolysis. Haematite (Fe₂O₃) is the main ore of iron. Malachite is a copper ore containing copper(II) carbonate hydroxide. Galena (PbS) is the main ore of lead.

CIE IGCSE Chemistry: Extraction of metals and their ores FAQ

How many CIE IGCSE Chemistry questions on Extraction of metals and their ores are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Extraction of metals and their ores for CIE IGCSE Chemistry, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CIE IGCSE students preparing for Chemistry?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Extraction of metals and their ores practice with other Chemistry topics or even switch to a totally different CIE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Extraction of metals and their ores questions aligned to the official CIE IGCSE Chemistry syllabus?
Every question is written against the published CIE IGCSE Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CIE.
How is Extraction of metals and their ores typically tested on CIE IGCSE Chemistry papers?
Extraction of metals and their ores appears across multiple question types on real CIE IGCSE Chemistry papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
