Title: Density tracers give option to float

Density tracers, that is, particles of precisely known specific gravities, offer alternative to the float-sink technique for determining separation densities. Usually made of plastic and dosed with heavy metal salts to obtain the desired specific gravity, the tracers are added to the separator feed, collected by hand from the product and reject streams, and sorted into appropriate increments on the basis of color-coding or other markings. After counting, the partition number for each specific gravity is calculated and the circuit partition or tromp curve drawn.
