how is copper ore separated from the host rock

The valuable minerals are then separated from the rock using a variety of physical and chemical separation methods. People have extracted minerals, for example iron and copper, from ores for thousands of years. Examples of how minerals were mined long ago can be found at archaeological sites in South-Africa, such as Mapungubwe.

The host rock is porphyry, schist, or other rock. Massive deposits are of higher metal content but of more limited extent; they may be oxidized in the upper portion with sulfides lower down. In mixed ores, nickel , zinc , or lead can accompany the copper; when such ore is mined, these other metals also are refined and sold as by-products.

The host rocks are sedimentary rocks of the Marquette–Baraga Supergroup comprising slates, iron formations, quartzites, and older cherty carbonate. The main Bovine intrusion is composed of a large gabbroic inner core with two thin rims in succession. The inner core (upper unit) is composed of fine-grained gabbro with thickness varying between 30 and 150 m.

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.

Secondary ores, called oxide ores, formed as weather and other natural forces altered ancient rocks. Both types of ore are mined and processed to extract the copper. Primary ore minerals of copper include malachite, azurite, chalcocite, bornite, and cuprite. One of the more familiar and beautiful minor ore minerals of copper is chrysocolla.

Rocks formed in this manner are termed cumulates and are often characterized by rhythmic layering. In ore deposits the alternating layers are often magnetite and/or chromite between layers of silicate. Ex. Bushveld igneous complex. Immiscible liquid - Typical example is oil and water. In ore deposits we deal with silicate and sulfide magmas.

The dip is to the north at 55 (fifty-five degrees) near surface and varies from almost sub horizontal to 40 in the lower western portion of the ore bodies. The contacts of the massive sulphide ore with the host rock are sharp.
