Evaluation of a New Fine Coal Cleaning Circuit Consisting of a Stack Sizer and a Falcon Enhanced Gravity Concentrator

Conventional and recent advances in gravity separation technologies for coal cleaning: A systematic and critical review

“…Many researchers reported that particle size is an important parameter for Falcon concentrator. Screening and classification, for examples, single-desk full-scale Stack Sizer [ 270 ] hydrocyclone [ 269 ], as a pre-treatment could improve the separation efficiency of Falcon concentrator. The increase in particle size by flocculation using polyacrylamide (PAM) as a flocculant to enhance the difference of settling velocity was studied by Zhu et al (2017) [ 271 ].…”

A review of state-of-the-art processing operations in coal preparation

“…Introduced in 2001, this technology has substantially lowered the traditional size limit for fine coal screening, with several researchers showing efficient separations as low as 75-100 [16][17][18]. The unit typically includes up to 5 parallel inclined screening decks, each separated into upper and lower sections.…”

Size-Dependent Model to Determine the Effects of Operational Parameters on the Performance of the Falcon Concentrator

“…Therefore, concentrators using centrifugal force for separation, such as spirals for finer sizes, have been used for more than half a century in the mineral processing industry. the Falcon concentrator (enhanced gravity separator) is generally considered superior to all the traditional gravity separation methods in terms of separation efficiency in finer sizes owing to its application of high artificial gravity force [5][6]. ıt has been used in industrial operations to upgrade metal and mineral ores, such as gold, sulfide, tin, and titanium.…”
