Extract

During the late war Mr Bruce Taplin received for mineralogical investigation a low-grade cassiterite concentrate from a small plant operated by the Non-Ferrous Mineral Development Control (Ministry of Supply) for the recovery of wolfram from the eluvial and alluvial gravels of the valley east of Buttern Hill, near the northern margin of the Bodmin Moor granite (fig. 1). As received, the sample contained 4·1 per cent, of tin.
