Look for igneous rocks. Igneous rocks are volcanic in origin, and copper is usually located in igneous rock formations that are surrounded by rocks that have been altered by volcanic pressure and high temperatures. These deposits are called porphyry copper deposits. In addition, search for rocks that are green or pieces of ore that have …

The ore is crushed and stacked into specially designed pads. The pads are lined with synthetic or natural materials such as polyethylene or compacted clay. Acids are introduced to copper-bearing ore, seeping through and dissolving copper and any other metals, including radionuclides. The liquid that "leaches" through the rocks is collected.
