Peacey et al. (2004) have reported the mining requirement of a 0.6% copper oxide ore for a large efficient heap leach operation with 80% copper recovery to be 3 ton waste /ton of ore for unit cost of US$0.69/ton. For a plant like this, sulfuric acid consumption was reported to be 10 kg per tone of ore.
Copper Beneficiation Process
Mineral Processing. As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.
Copper Processing | Multotec
Extraction of copper from ore begins with pre-treatment. Due to the decreasing concentration of copper in ores, this is an important step to decrease the volume of material and to increase the grade of copper in the ore. Most copper ores will only contain a small percentage of copper mineral, with the average grade being below 0.6% copper.

Crushing and milling account for just over 50% of copper mine site energy consumption 3 making them a primary target for cost reduction. The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Under-grinding reduces recovery; overgrinding reduces throughput and wastes energy.
