Abstract
Methods and apparatus for processing a material, the material being the upper layer from a metal melting process, the material containing one or more salts, the material containing one or metals, are provided. The method includes feeding the material to a size reduction step; feeding the material from the size reduction step to a density based separation step; feeding the material from the density based separation step to a leaching step. The size reduction stage is optimised to provide exposure of material for a ferrous and non-ferrous metal separation. The ferrous separation is preferably provided by an eddy current separator. The non-ferrous separation is preferably provided by a cyclone.
Claims14
A method of processing a material from a metal melting process, the material comprising one or more salts and one or more metals, the method including:
- feeding the material to a size reduction step;
- feeding the material from the size reduction step to a density based separation step;
- forming a cleaned salt stream at the density based separation step;
- and
- feeding the cleaned salt stream from the density based separation step to a leaching step.
