Magnetic separation using rare earth rolls (RER) and rare earth drums (RED) have seem tremendous development and use in recent years. While the process of magnetic separation is understood, the principles affecting the separation, the specific application and the optimization of RERs and REDs are less well known. This paper offers practical insight into the basic operation, selection and optimization of RERs and REDs. It is a guide for the engineer who must design a test series and select the proper equipment for that application. It provides the engineers and line operators who control the daily operation of the equipment a basic understanding of the dynamics of operation and the principles that govern the optimization of RERs and REDs.

The Nuggety Gully prospect is located 170 km (106 miles) south- east of Port Hedland and 40 km (25 miles) northeast of Marble Bar in the Pilbara Region, Western Australia. The area is held under title by Esso Exploration and Production Australia, Inc. The prospect covers a significant, but currently uneconomic body of molybdenum and copper mineralization of porphyry style, associated with Archean high level acid intrusives intruding sediments and volcanics of a narrow east-west Archean greenstone belt. The Nuggety Gully intrusive rocks have been dated at 3.2 b.y. ± 117 (de Later, oral communication). The current resource estimate for the deposit is 102 Mt (1 12 million st) of 0.1 1 % Mo and 0.15% Cu.
