Ore Sorting vs. Dense Medium Separation In Mineral Processing

Here's a rule of thumb, for ore sorting using a 1 metre wide belt, tonnes per hour equals particle size in millimetres. So, for a 30mm input, you can process 30t/h, 40mm would allow 40t/h and so on. Dense medium separators do not have this limitation and can handle inputs of over 200t/h at fine particle sizes in a single unit.
