Description & Prices of Density Tracers for Coal Applications

Nonmagnetic Tracers (8mm, 16mm, 32mm & 64mm)

These tracers are available in very precise densities from 1.24 g/cc to 2.20 g/cc. Density increments are as small as 0.01 g/cc, and the density of each tracer is indicated by engraving.

Density tracers with densities spanning the range of interest are added to the circuit feed and are manually retrieved from the product and rejects streams. They are bright pink to facilitate retrieval. For statistical confidence, a test may utilize some thousands of tracers in selected sizes and densities. After retrieval they are sorted into their various densities, and the resulting data are used to plot a partition curve.

The form of the curve can indicate whether the metallurgist should take actions such as adjust medium density, replace a worn circuit component, or correct an overload or medium instability situation.

Ferromagnetic Tracers (8mm & 16mm)

These tracers are available in very precise densities from 1.24 g/cc in density increments as small as 0.01 g/cc. The density of each 8mm or 16mm tracer is indicated by engraving.  The tolerance levels for tracers up to RD 1.80 is +/- 0.005, and the tolerance levels for tracers over RD 1.80 is +/- 0.01.

Density tracers with densities spanning the range of interest are added to the circuit feed and retrieved from the product and rejects streams with the assistance of magnets. For statistical confidence, a test may utilize some thousands of tracers in selected sizes and densities. After retrieval they are sorted into their various densities, and the resulting data are used to plot a partition curve.

The form of the curve can indicate whether the metallurgist should take actions such as adjust medium density, replace a worn circuit component, or correct an overload or medium instability situation.
