A new coarse cleaning device, the Stripa, has been developed for processing of coal in the size range of {minus}100 + 10 mm. The Stripa is an autogenous heavy medium separator originally developed for processing of iron ores. Although it has been employed in concentrating ores such as chromite, it has not been applied in coal cleaning. In this study, a pilot plant scale modified Stripa and its counterpart alternative, a diaphragm jig, are compared using subbituminous and lignitic coals. The separation performance of the Stripa and the diaphragm jig has been established in the light of washability properties of the coal samples. Comparison of the performance of the Stripa with that of the jig indicates that the Stripe can be used in coal preparation circuits as an alternative to jigs in the size range of {minus}100 + 10 mm. Simplicity, low initial investment, and low operating and maintenance costs make the Stripa a plausible candidate for coarse coal cleaning. More importantly, Stripa due to its short residence time, has a superior capacity over jig.
