  Copper Mineral Leaching Mathematical Models—A Review

  2022225 · Mineral leaching is the key unit operation in metallurgical processes and corresponds to the dissolution of metals. The study of leaching is carried out in many areas, such as geology, agriculture and metallurgy. This paper provides an introduction to the theoretical background regarding the mathematical modelling of the leaching process of …

  Base metals recovery from copper smelter slag by oxidising leaching …

  2002121 · Abstract Due to its amorphous structure, smelter slag cannot efficiently be leached with sulphuric acid; the formation of silica gel induces an increase of leach liquor viscosity, difficult pulp filtration and crud formation during solvent extraction. The problem was solved by leaching with sulphuric acid under hydrogen peroxide, which also performs …

  Solvent extraction separation of copper and zinc from MSWI …

  2015101 · A leaching and solvent extraction process for Cu and Zn recovery from municipal solid waste combustion fly ash was developed. Cu yields of 69–87% and Zn yields of 75–80% were obtained in laboratory scale experiments. Co-extraction of Fe, Pb, and Cd with Zn can be avoided by cementation before the Zn extraction.
