Pre-concentration of vanadium from stone coal by

2013-6-10  In the gravity separation stage, 28.9% of the feed ore were rejected as final tailings, while the V 2 O 5 loss was 9.7%. The pre-concentration of vanadium from stone coal can improve the V 2 O 5 grade and decrease the content of high acid consuming minerals. The benefits of the pre-concentration process in terms of cost savings and solving processing problems were discussed.

2021-6-7  The specific gravity of gold is 19.5 and the specific gravity of quartz (the common gangue mineral associated with gold) is 2.65 (i.e., gravity concentration works because gold is heavy, and quartz is light). Gravity causes gold to settle in water faster than silica and other gangue minerals.
