Separation Method Of Fluorite Ore And Scheelite
When gravity separates fluorite ore and scheelite, the difference in specific gravity between the two minerals must be considered. Fluorite has a relatively low specific gravity of about 3.2-3.3, while scheelite has a higher specific gravity of 5.9 to 6.1. This significant difference allows efficient separation using jig separators, shaking ...

Lead-zinc ores of the Shalkiya deposit in Kazakhstan are classified as refractory, but, given their significant reserves, remain one of the main potential lead and zinc mining targets. Selective flotation is recommended for the industrial processing of these ores, which, however, fails to ensure high lead and zinc recovery into the concentrates.
