<p>Separating apparatus comprises a separating vessel 10, which defines an interior cavity 12, for receiving a fusion of collector material and slag, and which further defines an outlet duct 18, disposed at the lower extremity of the separating vessel; a collector mould 20, disposed co-axially below the outlet duct for receiving the collector material; and a movable gate 22, disposed intermediate the separating vessel and the collector mould for controlling the flow of molten material from the separating vessel into the collector mould. The gate is movable between a first position in which it seals the outlet duct, and a second position in which it permits collector material to drain into the collector mould. A method of separating molten collector material and a molten slag with use of the separating apparatus is disclosed. Advantageously the separating apparatus is used in assaying mineral ore samples, inter alia to determine the concentration of gold and platinum group metals in such samples. In particular, the invention concerns separating molten collector material and a molten slag during such assay analysis.</p> |
