Introduction: In gravity separation, the shaking tables (gravimetric tables, shaker tables) are the most widely used and efficient sorting equipment for fine ore separation. The shaking table beneficiation is not just applied as an independent beneficiation method. Still, it is often combined with equipment such as jig separators, centrifugal concentrators, spiral …

Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.

Screening usually follows after comminution. The aim of this experiment was to screen and sieve haematite ore and to study its particle size distribution. The screening was done using an industrial screen and the sieving was done using laboratory Tyler sieves. The initial mass of the ore manually fed to the screen was 11.965 kg.
