An ore is a rock that contains enough of a metal compound to make extracting the metal worthwhile. Most metals are found combined with other elements, often as oxides or carbonates.
Step-by-step lessons on Edexcel GCSE Chemistry 5.1.3 Extracting metals from ores by reduction. Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
