The Concord heavy-mineral-sands mine of Iluka Resources in south-central ia. The mine excavates sand-silt deposits that contain about 4 percent heavy minerals, which were deposited along a shoreline that existed here between 3.5 and 3.0 million years ago. These ores are processed at nearby separation plants to recover the heavy minerals.
