the process of mining copper

Mining is the process by which valuable minerals such as copper, lead, zinc, gold and silver. are extracted from the earth. Usually these minera s are not found in their pure or native IOrm. but as components or other minerals. Copper, lead, and zinc Often bonded to sulfur, forming sulfide compounds. Thus, copper, and lead mining is often to as sulfide

Open Cut and Underground Mining | iMINCO

Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc. Stopes are large openings or rooms connected by tunnels in which miners drill and blast the ore. A pillar or wall is left between each room (stope) to prevent the mine from collapsing.

How is Copper Tubing Made? | Hunker

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

Coal Mining and Processing | Energy Trends Insider

Coal Mining and Processing. Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the topsoil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.

How Mining Works Resolution Copper
