Aqueous solution of aliphatic amine has a property to dissolve lead sulfates. With DETA, somm laboratory tests were tried to for the prepare high purity lead from lead concentrates, lead residues and copper anode slimes.
From these tests, it is obtained that:
(1) Lead in sulfate form can be extracted sufficiently with DETA
(2) Over-all loss of DETA is supposed to be less than 5% in one extracting cycle, including diminution of its extracting power.
Although DETA and other amines are so expensive at this stage as to use them in industrial scale, . it is expected in very near future that these amines with their lowered price can be used more widely in metallurgical extraction.
