Chapter 6 Copper Production Technology

Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods

12.3 Primary Copper Smelting

steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

Recovery of Copper by Solution Mining Methods

2 Recovery of Copper by Solution Mining Methods Solution mining replicates the natural process of oxidation and reduction, described above. Dilute acidic solutions are introduced to the copper-bearing ores, causing dissolution of soluble copper minerals (Table 1) remaining in the leached cap and underlying enrichment blanket.

The Role of Arsenic in the Mining Industry

Atmospheric arsenic emissions from copper smelting represent the largest contribution of arsenic from the mining and metals industry by far and have been the focus of pollution control technologies and increasingly stringent regulations. [8] Arsenic can also be leached out of some metal ores by cyanide or acid rock drainage

Ore characterization, process mineralogy and lab

Jun 01, 2014· The grinding efficiency (and related throughput) of porphyry copper ores in conventional mills is more impacted by certain alteration minerals than by the traditional “hardness mineral suite”. Consistent and daily mine/plant support mineralogy can provide major technical and economic improvements on vital KPIs such as: 1. Blast Indexing. 2.
