Heavy liquid separation (HLS)
Characterising response to gravity . Heavy Liquid Separation (HLS) tests provide key data for exploration programs and process design. Most commonly, data derived from HLS tests are used for: Characterising the density parameters of ore samples, predicting the performance of ores through gravity circuits, and/or pre-concentrating low-grade high …
