Unreactive. No reaction happens when copper and water are combined. This means that copper has a long useful lifespan. Metal ores are a finite resource and the availability of metal ores is rapidly decreasing. Mining is the traditional method used to extract ores from the ground, but this process causes significant environmental damage:
