Result comparison of heavy mineral separation with ...
Bromoform with different specific gravities is used normally in separation of heavy minerals;they are heavy liquid 1 with specific density of 2.87 g/cm3 and heavy liquid 2 with specific density of 2.80 g/cm3.The sediments with grain sizes from 0.25 mm to 0.063 mm from three big rivers and seas are studied for comparison of separation results,which include the Huanghe(the Yellow River),the ...

A Comparison of the Methods of Heavy Mineral Separation ...
2009-5-1 Extract. Methods and apparatus used in the isolation of heavy minerals vary considerably with different workers and this lack of uniformity obviously reduces the value of the conclusions in a branch of petrology in which quantitative data are essential. Panning in water and separation in bromoform are probably the two methods most widely adopted;

2021-4-3 Heavy mineral separation was done to know the percentage of heavy fraction in the raw sand. For the study Bromoform (CHBr 3) was used as density separator to separate the heavy from light minerals. The specific gravity of Bromoform is 2.9 at 200 C. The minerals that have specific gravity higher than the Bromoform are called heavy minerals.
