Hot Ferric Chloride Tanks For Moly Concentrates Patent US4500496 - Process for purifying molybdenite one of the most common leaching mediums for purifying molybdenite concentrate is a solution of ferric chloride molybdenum concentrate tank 6 where make-up This paper proposes a new leach process to treat copper sulfide ores or concentrates: the process operates under atmospheric pressure and uses limited concentrations of ferric sulphate as oxidant the key to the process is the regeneration of the ferric ion which can be effected in-situ (direct process) or ex-situ (indirect process) using SO2/O2

Remove Copper from Moly by Ferric Chloride Leaching

Here molybdenum concentrates are slurried with hot ferric chloride leach solution to dissolve the copper and lead contaminants present The primary function of the filtration and thickening circuits is to recover spent ferric chloride leach solution from the leached moly concentrates Since approximately 2 5 percent of the ferric chloride in

The Bureau found that leaching of the chalcopyrite concentrate from J:his source with ferric chloride concentrated nickel and cobalt in the residues at concentrations from 10 to 16 percent Ni and 8 to 11 percent cobalt with recoveries estimated at about 80 percent Froth flotation of reground and pretreated copper concentrates resulted in 67

This is done a few more times so that finally the molybdenum disulfide is floated off This rough concentrate goes through its own flotation circuit for further cleaning At the end of the production cycle it ends up with a high quality moly concentrate—molybdenum disulfide which is about 55% molybdenum At this point the molybdenum
