Feb 27, 2018 Noranda devised a process for treating a concentrate containing 0.36 pct Cu. This process comprised oxidative pressure leaching at 155 C and conventional precipitation techniques for cobalt recovery. No attempt was made to recover the copper. Because of unfavorable economic conditions, the mine was put on caretaker status in 1982.

The density of the slurry is measured automatically and continuously in the nucleonic density gauge Figure 3.23 by using a radioactive source. The gamma rays produced by this source pass through the pipe walls and the slurry at an intensity that is inversely proportional to the pulp density. The rays are detected by a high-efficiency ionization chamber and the electrical signal output is recorded directly as pulp density.

High slurry density sulfidic mineral leaching using

An energy efficient process is disclosed for the hydrometallurgical oxidation of sulfidic minerals containing copper, silver, nickel, cobalt, molybdenum, or zinc values. A high density slurry, e.g., 67 by weight solids, is prepared from a particulate sulfide mineral and water.

Jun 15, 2018 1. Introduction. Copper is one of the most important base metals and widely used as wire and conductors. In the earths crust, copper is most commonly present as copperironsulfide and coppersulfide minerals, such as chalcopyrite CuFeS 2 and chalcocite Cu 2 S 1,2.About 80 of the worlds copper ores originate in CuFeS minerals, especially chalcopyrite, which is the most ...

Tribocorrosion Study of Copper During Chemical Mechanical

Mar 10, 2015 Copper has been the main type of interconnect metal used for integrated circuits in devices with reduced dimensions 1, 2.Chemical mechanical polishing CMP is a key enabler for global and local planarization and has been intensively investigated from various angles 3, 4.According to the standard dual-damascene interconnect process for copper, the barrier layer TaTaN, Mo, Co, Ru,

Tribocorrosion Study of Copper During Chemical Mechanical

With an initial good field calibration, the accuracy is about 5 gl in the full range 1..3 SG and does not change during the lifetime of the probe. Furthermore, the responsetime is 1 second, so changes in the slurry density are observed immediately. These properties offer customers better process control.
