High-grade molybdenum concentrate can be obtained through selection. However, flotation is also difficult to reduce copper and lead to the standard of high-quality molybdenum concentrate. For this reason, the molybdenum concentrate is leached with hot ferric chloride or the like to reduce copper and lead to 0.054% and 0.033%.

Primary lead is now usually produced from sulfide concentrate by a smelting process that involves sintering, blast furnace reduction with carbon, and refining. ... In this method, galena concentrate is leached with hot ferric chloride-brine solution to obtain lead chloride and elemental sulfur: At 100° C, over 99 pct of the PbS in the ...
CANMET has developed a Ferric Chloride Leach (FCL) process to treat these relatively low grade bulk concentrates and to obtain very high recoveries of the contained metals. Typical extractions in CANMET's two-stage leach process are 99% for zinc and lead, 97% for copper and 96% for silver.
process involves ferric chloride leaching galena concentrate to produce lead chloride, followed by molten-salt electrolysis of the lead chloride to yield lead metal and chlorine. The chlorine is used to regenerate ferric chloride in the leaching solution. The process was tested on both a bench scale and alarger scale which had capacity of 225

For instance, from the data of Fig. 9, the model equation for 3.7 M ferric/ferrous chloride at 50 °C is E=523+60 log 10 [Fe 3+] [Fe 2+] Thus, if the ratio of ferric ions to ferrous ions is high (say 100, for a fresh solution) then the ORP (E)=523+60 log 100=523+120 mV=643 mV.
For a gallon of concentrate,, I use 5# dry FC and a gallon of distilled water ( slightly less concentrated). Add the powder to the water slow, outdoors. It will get hot, and give off chlorine.Wear safety gear....especially a face shield. For etching, I mix one part concentrate with three parts water. I store it in the etching tank.
1. Introduction. Ferric and/or cupric chloride leaching of copper from sulfide concentrates has some advantages over sulfate systems in supporting high metal solubility, enhanced redox behaviour, and increased rates of leaching (Dutrizac, 1990, Dutrizac, 1992, O'Malley and Liddell, 1987, Peters, 1977).Both cuprous and cupric ions …
Liquid catalyzed fuel cell (LCFC) is a kind of redox flow fuel cell directly converting carbohydrates to electricity. To improve its efficiency, ferric chloride (FeCl 3) was introduced as main catalyst.As mono catalyst, phosphomolybdic acid (PMo 12) was much better than phosphotungstic acid (PW 12) and FeCl 3 was intermediate between them. …

Stirred tank leaching was carried out at pH about 1.6, ... Bulk copper–molybdenum concentrates are thickened, after which the copper minerals are depressed, allowing molybdenite to float. ... does not dissolve in cyanide, and in some cases is leached with hot ferric chloride. Copper depression is achieved by the use of a variety of reagents ...
Description Ferric Chloride Storage Tanks. Ferric Chloride Storage Tanks – Ferric Chloride, also known as Iron (III) Chloride, Iron Trichloride and FeCl3, is a mineral hydrate solution whilst commonly used as an etching agent during the production of electronic circuit boards, is also used in the water industry as a flocculant during wastewater treatment.
minimum dissolution of molybdenum in the concentrate. Copper is present in the concentrate mainly as copper sulphide, chalcopyrite. Investigations were carried out on the removal of the sulphide by their selective leaching in sodium cyanide, ferric chloride and ferric sulphate solutions.
In this study we examine the feasibility of applying the process to a complex ore concentrate containing both pentlandite and chalcopyrite through the use of a horizontal ball mill for the mechanical activation of chalcopyrite, using a concentrated (∼5 M Cl −) ferric chloride solution for the leaching. The kinetics of dissolution are ...
