Abstract
A process for separating a fusion mix sample comprising a slag material and a collector material using a separator. The separator comprising a plurality of impact members configured to rotate. The process comprising the steps of providing a solid fusion mix sample and loading the solid sample into the separator. Dislodging the slag material from the solid fusion mix sample by rotating the impact members and contacting the rotating impact members and the solid fusion mix sample. Separating into a first fraction substantially comprising the collector material and a second fraction substantially comprising slag material.
Claims14
A process for separating a fusion mix sample comprising a slag material and a collector material using a separator comprising a plurality of impact members configured to rotate around a center axis of the separator, the process comprising at least the steps of:
- providing a solid fusion mix sample and loading the solid sample into the separator;
- dislodging slag material from the solid fusion mix sample by rotating the impact members and contacting the rotating impact members and the solid fusion mix sample to provide a collector material and a slag material;
- separating by specific gravity using a gas flow and optionally centripetal forces on the loosened slag to provide a high-density fraction substantially comprising the collector material and a low-density fraction substantially comprising slag material.
The process according to any previous claims, additionally comprising the step of:
- providing a liquid fusion mix sample comprising collector material and slag material;
- separating, while in the liquid state, the collector material from a portion of the slag material by removing a portion of the upper layer of the liquid fusion mix sample;
- cooling the remaining liquid fusion mix sample to provide a solid fusion mix sample.
An apparatus for separating a solid fusion mix material into a collector material and a slag material, the apparatus having a separating unit, the separating unit defining a central axis, and comprising
- a separation chamber having an inner surface and having a top portion and a bottom portion arranged with respect to the central axis
- an inlet configured to allow entry of a solid fusion mix material,
- an impact member configured to rotate around the central axis by rotating means and adapted to contact a solid fusion mix material in the separation chamber while rotating, to dislodge slag material and thereby separate the solid fusion mix material into a slag material and a collector material;
- and
- at least one outlet allowing extraction of separated slag material and/or collector material from the separating chamber.
