    This causes gold to collect on the negative terminals. Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers

  • Why is recycling copper better than extracting copper
    Why is recycling copper better than extracting copper

    Why is recycling copper better than extracting copper? It is cheaper to recycle copper than to mine and extract new copper. Recycling a tonne of copper uses 15% of the energy that would be used to mine and extract the same copper. So recycling helps to conserve the world’s supply of fossil fuels and reduce carbon dioxide emissions

    Extraction of Metals. What is a Metal Ore?. A solid element or compound which occurs naturally in the Earth's crust is called a mineral.A mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore. Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling
