Crushing & Grinding – The Anchor House, Inc.
The purpose of crushing and grinding is to reduce the size of the potential ore particles to that where there is sufficient REE mineral liberation and the size/size distribution is suitable for the chosen downstream mineral recovery process. This allows for the subsequent REE mineral recovery processes to function in an economically efficient ...

Laboratory Testing & General Mineral Processing Engineering
Lab rod mills tend to produce a particle and mineral P80 of similar size (can vary when high levels of mica or similar), but the plant closed circuit mill with a hydroclone can give finer grind size of the heavier minerals. This ultimately might mean that that the plant grind size can be coarser than the lab grind size.
