Fluor is the world leader in development of hydrometallurgical and pyrometallurgical processing plants for the copper industry. Our project experience extends from initial evaluative studies to the engineering, design and construction of concentrator facilities, smelters, electrorefineries, heap leach, solvent extraction and electrowinning projects.

Mining Cost Service continues to be a useful reference on a wide range of topics for early stage mine planning through to ''fill the gaps'' on more detailed studies. Mining Cost Service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.

This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of preconcentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners ...

Mining and Processing Methods. Ores that contain copper in the are typically mined in large, openpits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
