density separation references

[johngerhart]

I am looking for references to study density separation of one solid material from another . Would someone please suggest references. thanks

Can you be a little more specific? Do you mean different density materials in a slurry?

 

[johngerhart]

Yes , I am talking about different density solids in a slurry with about the same particle size . Doing multiple density separations , varying the liquid density . thanks

We use hydrcyclones for density separation but it's mostly different particle sizes in the same density fluid- I'll check with our metallurgit though- he may have some references- Krebs is the big name in mining- also Dorr-Oliver - either may help

Two good refernce works are the Mineral Engineering Handbook and Coal Preparation both avialable through the Society of Mining Engineers at

You can get a good Idea if you read Introduction To Mineral processing by Kelly & spottiswood, Introduction To Mineral Processing by B.A.Wills. Other books by Godwin and one more by Richard.O.Burt
The most common equipments are spirals, Hydrocyclones, Flotex, Jigs, wettables etc. you can visit the web site of Carpco

MDL etc also

A centrifugal gravity concentrator by Knelson is boasted a recent innovation of gravity seperation tool. See link

By any chance are you referring to density tracers? Blocks of known density that are placed in a streaming to trace how well the unit is performing.

See: Evaluation of Coal Cleaning Efficiency Using Transponder-Based Density Tracers (

No, It's a machine to seperate heavier minerals from lighter minerals like spirals. It is used in Gold mine or other mines with proper mineral gravity difference.

But the density tracer you mentioned is interesting, I did not know it before.
