Mining Dilution and Recovery – Australia Mining Consultants

Mine dilution occurs due to the selected mining method selected and from over break during the mining process. In other words, dilution is the waste material not separated from the ore in the stages of mining either in the phase of development or stoping. Figure below shows a typical primary dilution in narrow vein mining.(ref: Crawford, 2004)

Ore Dressing

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.
