WEBDec 15, 2021 · To create large mass clean coal composites, bulk jigging was done. The process of cleaning the coal can be sped up by eliminating some of the detail in the washing process (, finding a 'cut point' in the jig column). First, a trial is carried out by jigging 15 kg of raw coal and removing 12–18 slices from the jig column.
