Flowsheet considerations for copper cobalt projects

Flowsheet considerations for copper cobalt projects outputs (stream flows and copper and acid concentrations) from the Metsim model are included in the relevant schematics. Flowsheet 1—Conventional circuit Flowsheet 1, the Conventional Circuit, is a simplified (and amended to include cobalt recovery) version of the metallurgical flowsheet that has been in use for many years at the

Spatial Separation of Copper and Cobalt Oxalate by Flow

14/08/2017 A precipitation reaction is investigated far from equilibrium by introducing a continuous flow of the homogeneous mixture of water-soluble metal salts into sodium oxalate solution. The spreading gravity current maintained by the density difference between the solutions creates a radially symmetric precipitate pattern that contains spatially separated copper oxalate monohydrate and cobalt

(DRC) copper-cobalt production is coming to the fore once again after a 20-year period of decline. This paper highlights the technological developments that have made the increased production possible, particularly trends over the last 10 20 years, discusses cobalt product selection for new projects and reviews the status of several technologies available for cobalt production flowsheets

New BEOL/MOL Breakthroughs? Semiconductor Engineering

15/06/2017 Cobalt is a higher resistive material than copper. But at certain dimensions, cobalt may show a lower resistance than copper. “Cobalt, on the other hand, has a mean free path that’s about four times lower than that of copper. What this means is that cobalt wire can be scaled down much further than a copper wire without a significant increase in electron scattering. In other words, cobalt
