Abstract
Abstract Phase disengagement between aqueous copper sulfate solutions and organic phases containing a liquid ionic change reagent is greatly facilitated when the dispersed medium from the mixture stage is contacted counter-currently to the direction of phase separation with a small amount of the respective separated phase having uniform appropriate droplet size.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
81 words
A method for counter-current phase separation of aqueous copper sulfate solutions and organic phases in substantially vertical settler tanks and substantially horizontal settler pipes wherein the aqueous copper sulfate solution and organic phase are contacted counter-currently to the direction of phase separation, comprising compartmenting the bottoms of said tanks and pipes, flowing said solutions and organic phases over said compartments to coalesce the organic phase to form droplets, said droplets then rising to contact the aqueous solution and facilitate phase disengagement.
Claim 2
Independent Claim
81 words
A method for counter-current phase separation of aqueous copper sulfate solutions and organic phases in substantially vertical settler tanks and substantially horizontal settler pipes wherein the aqueous copper sulfate solution and organic phase are contacted counter-currently to the direction of phase separation, comprising compartmenting the bottoms of said tanks and pipes, flowing said solutions and organic phases over said compartments to coalesce the organic phase to form droplets, said droplets then rising to contact the aqueous solution and facilitate phase disengagement.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein the droplet size ranges from about 0.001 cubic centimeter to about 0.05 cubic centimeter.
Claim 4
Dependent Claim
29 words
The method of claim 1 wherein the velocity of contact is from 1 gallon per minute per square foot up to about 10 gallons per minute per square foot.
Claim 5
Dependent Claim
14 words
The method of claim 1 wherein the organic phase contains an ion exchange reagent.
