Why preconcentrate, and how? Mining Magazine

This requires the mining and processing of much larger volumes of material per tonne of product. The aim of preconcentration is to remove barren material as early in the process, and at as coarse a particle size as possible, to reduce the amount of material requiring downstream comminution and processing.

Preconcentration an overview ScienceDirect Topics

Pre-concentration was performed at neutral or slightly basic pH, where the carboxyl acid groups of the peptides are negatively charged. For desorption, a pH lower than three is chosen, at which the peptide carboxyl groups are protonated.

The reverse osmosis (RO) process, performed on a laboratory plant unit, was used to preconcentrate the permeate coming from the UF step up to 15–20 g TSS/100 g. A final osmotic distillation (OD) step yielded a concentration of the retentate coming from the RO up to 60–63 g TSS/100 g at an average throughput of about 1 kg h m −2 .
