The copper tail is the solid waste material left during the purification of precious copper from the copper ores. Disposal of copper wastes is one of the major environmental problems in a copper mine. To prevent uncontrolled release of copper tailings material into the atmosphere; copper mines generally have a spillway or pond installation. This is a convenient form of storage when tailings are often in the form of grout when they are discharged from the concentrator.
Concrete is one of the most important building materials that have been used around the world. The aggregate occupies almost 75% of the volume of concrete and acts as the main constituent materials of concrete in addition to cement and water. The types of aggregates used are coarse aggregates and fine aggregates. During the hydration process, the coarse aggregates are bound with cement paste to form cement concrete, while the fine aggregates fill the spaces between the coarse aggregate particles. Copper casting is one of the materials that is considered as a mining waste material that could have a promising future in the construction industry as a partial replacement of cement or fine aggregates. Copper tailings have been included in Group III along with zinc and gold tailings that have been studied for use as fine aggregate or concrete filler material. Most of the wastes listed in Group III have not yet been evaluated as they are in the form of sludge: water must be removed before they can be used as fine aggregates or as a filler in concrete or bituminous putty. Tailing consists of earth rocks and process effluents that are generated in a mine processing plant. . Mechanical and chemical processes are used to extract the desired product from mine exploitation and produce a waste stream known as tailings.
