Copper Ore Mining: Exploration, Extraction, and Processing
For example, to smelt 1 ton of cast iron, it is necessary to extract on average 2-3 tons of ore, and to obtain 1 ton of copper, mining and processing plants need to process more than 200 tons of ore. Therefore, to ensure the specified production volumes, it is difficult to imagine the figure representing the amount of ore processed per year.
