crushing and grinding of copper ores

Copper Department of Energy

Crushing and grinding is the most energy intensive. The methods selected vary according to ore characteristics and economic factors. Approximately half of copper beneficiation occurs through dump leaching, while a combination of solvent extraction, froth flotation, and electrowinning is generally used for the other half.
