  Kinetic Investigation on Leaching of Copper from a …

  2022811 · In general, these investigations indicated that sulfuric acid leaching was the most practical and commonly used method to extract the metals from low-grade resources due to the simplic-ity, ease of the process and lower production costs. Also, shrinking core models (SCMs) gave a better description from leaching process of copper.

  Why Zijinshan copper bioheapleaching plant works efficiently at low ...

  201371 · Zijinshan commercial bioheapleaching–SX–EW plant has been in operation since December 2005. 13.9 million tonnes of low grade copper sulfide ore (Cu 0.38%) has been leached efficiently with an annual recovery of 80% in this distinct leaching system with high iron concentration, high temperature, high acidity and low microbial activity. This …

  Ore agglomeration behavior and its key controlling factors in …

  2021110 · Abstract The particle segregation, stratification, excessive feed size of non-agglomerated heaps chronically leads to poor heap permeability and leaching efficiency. Thus, owing to well-developed dual pore structure, desirable liquid retention and better leachability, the ore agglomeration has been widely utilized to recover copper metals from …

  New insights into the mechanism of pyrite oxidation in copper ...

  202429 · The nontoxicity, low cost, and environmental friendliness of the Cu–NH–SO gold leaching system make it a viable alternative to cyanide-based systems. However, the strong influence of certain sulphide minerals (e.g., pyrite) on the performance of the former system complicates its compositional regulation. Herein, the mechanism of …
