The drawback of spirals is that they are density separators that are unable to obtain a D 50 lower than 1.65 g/cm 3 but tend to have a D 50 between 1.7 and 2.1 g/cm 3 and misplaces a significant amount of ash fines into the clean coal. Even the application of wider diameter spirals couldn't solve this problem. ... Run-of-mine (ROM) chromite ...

Low-rank coal such as the coal in the Powder River Basin (PRB) is typically direct shipped without any need for upgrading. Due to the lack of on-site processing capabilities, coal that is mixed with out-of-seam dilution during the mining process is typically left in the mine pit. In some cases, the loss could amount to 5% of the total …
PVDF-co-HFP has been proposed as a promising separator due to its superior wettability to organic electrolytes, and thermal stability [25].A large amount of ordered PVDF molecular chains in PVDF-co-HFP separator with high crystallinity provides limited free space for lithium ion to pass through, resulting in lower conductivity [42].The …

Diamonds have a density of 3.5 g/cm3, in an ideal diamond separation the material above the density of 3.3 g/cm3 has to report to sinks. Figure 1 indicates that as the feed rate is varied the separation efficiency deteriorates especially near the diamond density material of 3.5 g/cm3; this indicates that as feed rate increases

complexities of the ore, multi-stage dense media separators like the Condor can offer some advantages over the single-stage dense medium cyclones. The main advantage in using a multi-stage separator is the ability to produce multiple sink products and being able to fix the density cut points of each individual stage.
Such separation is done on the basis of particle size as well as particle density. Larger particles with greater density under the influence of centrifugal force are thrown outwards and are collected first then successive particles with relatively less size and density are collected.
