Leachingkinetics ofelectronicwaste for the recovery of

Oct 26, 2020·Electronicwaste (e‐waste) contains metallic values that can be recovered by hydrometallurgical methods. This investigation addresses theleachingkinetics of e‐waste for the recovery ofcopperin H 2 SO 4 ‐H 2 O 2 media with the objective of determining the rate‐controlling step in monosize particle systems. The results are then used to develop a kinetic model forcopper…

Recycling gold andcopperfrom waste printed circuit

Theleachingyield ofcopperincreased with increase in ball-millingtime. For gold, there was an optimal time around 10 min at 20 s −1 frequency ofmilling. Theleachingyield of gold could reach more than 99% after a pretreatment with ballmillingfor 10 min when theleachingtime was 90 min, theleachingtemperature was 40 °C and the ...

RecoverCopperbyLeachingSulfidation Partitioned

The results (table 6) show that ballmillingfor 4 h (wet) resulted in a higherleachingrate due to the much finer particle size subjected toleaching. When the sulfidized concentrate was ball milled to essentially all minus 400 mesh, greater Cu extraction resulted in 2 h ofleachingwith FeCl3 than occurred whenleachingthe coarser as ...

Leaching Mining Fundamentals

Leachingis a chemical process in mining for extracting valuable minerals from the ore.Leachingalso takes place in nature where the rocks are dissolved by water. Postleaching, the rocks areleft with smaller proportion of minerals that they originally contained.

BiologicalLeachingand Selection ofCopperProduction

The following is a brief introduction of biologicalleachingof acopperproduction line. Common microbe mineral processing technologies are heapleachingandleaching. Heapleachingmeans to heap mined ore and then use microbeleachingsolution. Due to its production cost is low and less pollution, it has been widely used.
