Why alternative methods are needed

A metal ore is a rock containing enough of a metal compound for extraction to be economically worthwhile. The Earth's supply of rich copper ores is finite, so the remaining ores are often low-grade.
Step-by-step lessons on AQA GCSE Chemistry 10.1.4 Alternative methods of extracting metals (HT only). 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.
