The Knelson Concentrator is a compact centrifugal separator with an active fluidized bed to concentrate high SG minerals (Knelson, 1992, Knelson and Jones, 1994). It was initially developed for gold processing, which commonly employed semi-batch units, as the yield to the concentrate was typically below 1%.
Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity …
Although for the similar centrifugal type concentrator, i.e. Falcon concentrator, there exist some numerical modeling and simulation studies based on fluid dynamics approach for ultrafine particle beneficiation [33], [34], there is no published report regarding numerical simulation of separation process inside the Knelson concentrator …
ABSTRACT In this study, the −1 mm fine coal is treated in a laboratory Knelson concentrator. The influence of various parameters (e.g., feed rate, solid content, centrifugal force, and the fluidization water pressure) on the yield and ash content of clean coal are thoroughly investigated and estimated by statistical polynomial models obtained using …
