Gravity Concentration an overview ScienceDirect

Silvia Serranti, Giuseppe Bonifazi, in Use of Recycled Plastics in Eco-efficient Concrete, 2019. Jigging. Jigging is one of the oldest methods of gravity concentration (Hori et al., 2009).Jigging can be defined as an “enhanced gravity based separation” method: a water stream is pulsed, or moved by pistons upward and downward, through the material bed.
