Coal flotation is the most proficient technique used to improve the nature of fine particles by diminishing pollution substance (Majumder and Barnwal, 2011). The hypothesis of froth flotation is complex and has not been fully comprehended. This reality has been brought by many difficulties observed in coal preparation plants (Ye et al., 2017).

Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a low-ash coal product at high efficiency. Our high-performance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH (1.8 mtph to 2.7 mtph) per start, dependent on raw coal quality and refuse amount to be discarded.

The Jameson Cell is now the industry standard with over 100 coal cells installed by 2010 in Australia alone. In a Coal Handling and Preparation Plants (CHPP) gravity separation techniques are used to separate coal from ash. At fine particle sizes (below 500 µm) gravity separation is inefficient and flotation is required.

This paper focuses on the −½ mm cleaning at Elk Run Coal. The original circuitry incorporated desliming cyclones. Problems with slimes entrainment in the cyclone underflow (froth cell feed) resulted in poor froth cell selectivity. Laboratory test work led to the installation of high frequency desliming screens. Consequently, great improvement in …
