For low-grade manganese ore, ore dressing must be carried out. However, since most manganese ores are fine-grained or micro-grained and have a considerable amount of high-phosphate ore, high-iron ore and co-existing (associated) beneficial metals, it brings great difficulty to ore dressing and processing.
