Abstract
Working up of sea bed solns. contg. solid Fe and non-ferrous minerals consists of passing the soln. through a filter or centrifuge and subjection of the solids so recovered to an oxidising or chlorinating roasting treatment, in pref. a shaft or multiple hearth roasting furnace, followed by a trickel or stirring acid soln. treatment. Alternatively to filtering or prior to it a flotation or magnetic separation treatment is applied. The method is a means of recovering metals from continental shelf-sea beds, the solns. from the bottom of which can be pumped up through pipes.
