First, you need to understand what a Large Resource Deposit is, and it is a big mound of a specific type of raw material. When it is harvested, it will break into several pieces and it is a great way to gather large amounts of a single resource. The resources you will find as Large Resource Deposits include: Copper Ore Gold

Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.

Ore Minerals. Copper in these deposits generally occurs in copper-iron sulfide minerals such as chalcopyrite (CuFeS 2) and bornite (Cu 5 FeS 4). Brassy chalcopyrite is one of the common ore minerals in porphyry deposits. Over time, weathering of the near-surface rocks and the infiltration of surface water, can cause secondary copper-bearing ...

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
