Copper is one of the few materials that can be recycled repeatedly without any loss of performance. There is no di erence in the quality (physical and chemical properties) of recycled copper (secondary production) and mined copper (primary production), thus they can be used interchangeably. Around 30 percent of the world’s annual copper demand is met through …

What is primary and secondary copper? Customarily, primary production is the output from ores, and secondary production is produced from recycling scrap. (Gómez et al., 2007). To extract primary copper from copper ore, there are two technologies, hydrometallurgy for low-grade like oxidized copper ore and pyrometallurgy for sulfide copper ore.

2025610· To access the growing (and partly uncollected) scrap pool, copper producers should consider partnerships and investments in the copper scrap collection and processing value chain. As these secondary-copper value chains develop, there will likely be greater competition to secure postconsumer scrap volumes, making it critical to be more proactive.

The secondary mineral assemblages in the ore zone are mainly iron, copper, and magnesium sulphates, whereas the lakeshore assemblage is dominated by magnesium-, calcium-, sodium-, and aluminum-bearing sulphate minerals. Near the lakeshore, the highly soluble iron sulphate salts dis-solve in the lake water, increasing its iron content.
