The Cuajone mine, loed in the rugged Peruvian Andes at 12,000 feet, was the largest single copper mine and smelter complex ever built. Fluor provided detailed engineering, procurement and construction management services along with training for 7,000 peak local workers.
The development of the sword was not possible until ancient civilizations discovered how to mine and work metal. Thus, the first swords were probably made of the oldest worked metal, pure copper.

THE BASIC PROCESSES OF GOLD RECOVERY INTRODUCTION. Man has held a fascination with recovering and acquiring gold almost since the beginning of time.
Ore will be separated from the minerals following a crushing and grinding process. Using froth flotation, the majority of the copper and molybdenum minerals will be separated from uneconomical minerals.
The CuPbZn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage.

Flotation Separation Valuable mineral in an ore such as chalcopyrite ore can be separated from each other and from worthless gauge minerals by the froth flotation process.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
Millions of tonnes of lowgrade ore and copperrich tailings await the development of an efficient and economic bioleach process for chalcopyrite (CuFeS 2).The bioleaching of chalcopyrite in situ and in dumps is a practical option only because the low and slow recoveries are countered by the low processing costs (Schnell, 1997).Not surprisingly, .

Copper extraction refers to the methods used to obtaining copper from its conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Copper processing: Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products.
The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an openpit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh mine is the largest manmade excavation in the world and is considered to have produced more copper than .
Producing nearly a quarter of global copper, these gigantic mines are undergoing multibillion dollar expansions.
