Abstract

This invention relates to a separating apparatus and a separation method for quantitative separation of molten collector material and a molten slag during a process of assaying mineral ore samples to determine the concentration of selected metals, particularly of gold and platinum group metals, in such samples. The separating apparatus comprises a separating vessel for receiving a fusion of collector material and slag; a collector mould disposed below the separating vessel for receiving the collector material; and a movable gate 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 separating apparatus defines a closed flow path between the separating vessel and the collector mould such that the collector material is not exposed to atmospheric air during casting.
