From its initial state as copper ore, the journey to becoming a high-quality concentrate suitable for diverse industrial uses is long and intricate. The process of turning this ore into a copper concentrate involves multiple steps, spanning from mining copper to chemical …
Low-grade copper concentrates (with copper content less than 20%) often contain impurities such as arsenic, zinc, lead, mercury, antimony and bismuth. The pyrometallurgical treatment of such concentrates is associated with several problems, which will ultimately affect the cost and the quality of copper cathodes as well as by-products.
ABSTRACT In recent years, with the rapid growth of the amount of electronic equipment, the environmental pollution caused by waste printed circuit board (WPCB) has become increasingly serious. Co-processing of WPCB and copper concentrate is an economic and effective way to realize the resource utilization of WPCB. However, there …

A greenhouse experiment was conducted to study copper bioavailability and bioaccumulation in agricultural soils spiked with different types of copper-rich mine solid wastes (copper ore, tailing sand, smelter dust, and smelter slag) and copper concentrate. A copper salt (copper sulfate, CuSO4) that frequently is used to assess soil copper ...
With a nuclear microprobe, the authors quantified copper and other metals in the hydrothermal fluids. The concentrations of copper are extraordinarily high: ∼10% by weight in the liquid and ∼4% by weight in the vapor. These results suggest that second boiling at high pressure and temperature, prior to first boiling, is exceptionally ...
