world’s biggest copper companies use concentration plants, which are energy intensive and use the world’s biggest pumps in their main production process. The distribution of energy at a mine site is 3 – 5% for blasting, 5 – 7% for crushing, and 80 - 90 % for grinding [10, 11]. Energy consumption occurs everywhere in the mining and

Copper mining. From ore to copper. - Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper - for this reason, leaching extraction is growing in importance. Picture 4. Map of copper production. Compare this with the pie chart of production.
