METHOD FOR SEPARATION OF A MOLTEN MIXTURE

摘要

The invention relates to a method for separation of valuable metal from a mixture of molten materials, which contains the valuable metal, but which mainly consists of molten slag. The characteristic features are that there is established a stream (13) of said mixture of molten materials and that water is sprayed against the stream of the liquid mixture of molten materials in such an amount and with such force that the mixture is disintegrated (is fragmented) to form drops or fragments of varying sizes, which are rapidly cooled to form a granulate consisting of a coarse fraction (B), which contains the main part of the valuable metal, and a finer fraction (A), which contains the main part of the slag of the initial mixture.
