Functional classification divides frothers into two groups. The first group are standard frothers, which help to disperse bubbles and form a froth (Grau and Laskowski, 2006, Melo and Laskowski, 2006, Khoshdast and Sam, 2011, Khoshdast et al., 2011).The structure of these frothers consists of one or a few hydroxyl groups and a hydrophobic …
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 …

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.

G-Cell achieves froth separation in several seconds due to high tangential velocity and limited capacity of the separating vessel. This phenomenon may ...
at the Peak Downs preparation plant located in Australia.As shown in Figure 1 (above), the column cell achieved higher size by size recovery when compared to the Jameson cell. Based on these results, Eriez column technology was selected for the expansion projects at Peak Downs and, subsequently, the Saraji preparation plant.
The froth collected from the third and fourth cells of the 4-cell flotation machines in this plant was further re-cleaned to obtain qualified clean coal. Laboratory-scale results show that both the mechanical flotation machine and flotation column as re-cleaning flotation devices could produce the clean coal with qualified ash content.
The present study has investigated the suitability of the G-Cell technology for cleaning fine coal using a 0.8 m diameter prototype unit at a coal preparation plant operating in the Midwestern ...
The 2,000 t/h Peak Downs coal preparation plant has historically produced prime coking coal, through dense medium cyclones and sands/slimes froth flotation in conventional cells. Over two decades the conventional sands/slimes flotation circuit had been optimized. During 1993 three novel flotation devices were tested on the plant in …
