Recovery of Chromite Values from Plant Tailings by Gravity Concentration
This table shows that the Cr 2O3 content varies from 18.2% to 29.26% and most of the Cr 2O3 (about 51.18% by wt) is distributed in the size range -250 and +25 microns. But huge quantity (30.56% by wt) of Cr 2O3 value is distributed at finer sizes i.e. below 25 micron. The total iron content varies from 13.23% to

The average residence time of ore on a table is 7 minutes for 100 pounds of ore. Most gravity tables have a sand deck for treating 1/8" to 80 mesh material and a slime deck for treating -80 mesh material. The appropriate deck should be used when treating ores. Most used involve the sand deck. Now, for a gold pan, a very good panner can take a ...

How to Recover Chromite - Metallurgist & Mineral Processing Engineer
The chromite content varied in the different size fractions and is listed in table 4. Chromite gram analyses ranged from 60 to 70 pct Cr2O3. Liberation was measured by grain counting and was performed on all the size fractions. This ore began to show chromite liberation around 20 mesh and was nearly liberated at 65 mesh.

Recovery of heavy minerals from slimes - ScienceDirect
Burt {1980) has expressed his preference for a H01man slime table to a Deister slime table. The low riffles found on the Deister table can be expected to seriously disturb the stratification when treating feeds containing high amounts of very fine particles. Much higher upgrading is pos- sible on a slime table if the feed is of the correct nature.
