· In mineral processing, liberation of valuable mineral from gangue minerals is the most important stage before the concentration process. Comminution, which leads to liberation, includes two types of random and non-random breakages. The contribution of random and non-random breakage is very important in modelling the liberation phenomenon.

· If you don''t have BOD data, you can use your COD data and a COD/BOD ratio of 2.1 as a starting point. Use the 2.1 ratio value with caution though as it is highly variable from one wastewater system to another. The equation below assumes you also don''t have MLVSS data so you can use your MLSS data estimating that the MLVSS is 72% of the MLSS.
