How do rocks provide metals and how are metals used? Ores contain enough metal to make it economical to extract the metal and this changes over time. Low density and resistance to corrosion make aluminium and titanium useful metals. These metals cannot be extracted from their oxides by reduction with carbon. Current methods of extraction are expensive (many stages, much energy). AQA GCSE Additional Science (4463) Chemistry II. Additional materials 1.
