Abstract
Disclosed is a method for recovering from dilute aqueous solutions metals below iron in the electromotive series by percolating the solutions through iron particles having a size such as will pass completely through a 100 mesh sieve, or by intimately mixing the solutions and the iron particles, followed by filtration or centrifuging. The iron particles are "swarf" produced by the grinding of ferrous metals.
