Cobblestone Beneficiation By Jigging Process

Statistical optimization study of jigging process on ...

Jigging is one of the unit operations used for beneficiation of coal. Beneficiation by jigging is carried out for the coarser size of particles. Jigging of fine size coal is limited. However, in present study two fine non-coking coal samples having sizes −3+2 mm and −2+1 mm were used for jigging study.
