Aug 01, 2020· As seen in this diagram, the copper concentration in the electrolyte solution can be increased from 30 to 50 g/l of Cu, and the loaded organic can be discharged from 4.25 to 0.75 g/L of Cu using only one stripping stage at 96% efficiency for an O/A flow rate ratio of 5.71.

Pump sizing involves matching the flow and pressure rating of a pump with the flowrate and pressure required for the process. The mass flowrate of the system is established on the process flow diagram by the mass balance. Achiev-ing this mass flowrate requires a pump that can generate a pressure high enough to overcome the hydraulic resistance

Flow Diagram of Copper Recovery by SX-EW, showing possible routes for the spent electrolyte to be recycled within the circuit An alternative to recycling the bleed is to electrowin the copper from the bleed; this low copper, high acid solution can then be sent to either the raffinate for higher leach recovery, or E1 for higher SX recovery.

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

The preceding experiments were designed to understand the effects of flow rate and applied current, which are the two major operating variables of an emew® cell, on copper and bismuth recovery. Using the information gained, two additional experiments were designed with the goal of removing a significant quantity (>90%) of copper and bismuth ...

Chemistry questions and answers; A new copper processing facility is being constructed where a pressure of 0.2 atmospheres SO_2 is desired while oxidizing copper matte. Superimpose this pressure in Equation 3 onto a predominance area diagram of the Cu-S-0 system: Use log(pS_2) on the y-axis and log(pO_2) on the x-axis.

The term pipe flow in this course is being taken to mean flow under pressure in a pipe, piping system, or closed conduit with a non-circular cross-section. Calculations for gravity flow in a circular pipe, like a storm sewer, are done with open channel flow equations, and will not be discussed in this course.

The copper anode is dissolved and deposited at the cathode. As the copper anode dissolves, metallic impurities precipitate and form a sludge. Cathode copper, 99.95 to 99.96 percent pure, is then cast into bars, ingots, or slabs. 12.3.3 Emissions And Controls Emissions from primary copper smelters are principally particulate matter and sulfur oxides
