An ore is a rock that contains enough metal to make it worthwhile extracting. The main copper ores are: chalcopyrite bornite malachite. Grinding: The ore is crushed then ground into powder. Concentrating: The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting: This is where the chemical reactions start.

Copper processing - Ores Britannica

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

Heap leaching - Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

Copper Mining and Processing: Life Cycle of a Mine

An ore reserve is the part of the mineral resource that can be economically profitable to mine (i.e., there is enough valuable metal to be worth removing it and extracting it from all of the surrounding rock). After a deposit has been identified as an inferred, indicated, or measured mineral resource, it is next labeled as a “probable” or “proved” ore reserve. This classification is ...
