Ore Sorting Strategies In Mineral Processing

Ore sorting is also a simpler process with a small footprint. Benefits Of Dense Medium Separation. While dense medium separation can only rely on density to distinguish valuable materials from waste, it has the advantage of being able to sort a wider range of particle sizes. With ore sorting, the largest particle size should be no more than 3

Flotation ore dressing Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.
