Jun 29,  · Dry Concentrate Etchant (Ferric Chloride) Ferric Chloride is the best choice for etching copper PC boards. Datak supplies FeCl in a dry, powder form and the user must add it to water to make the etching solutions/5(2). RECOVERY OF SILVER, GOLD, AND LEAD FROM A COMPLEX SULFIDE ORE USING FERRIC CHLORIDE, THIOUREA, AND BRINE LEACH SOLUTIONS By R. G. Sandberg 1 and J. L. Huiatt 2 ABSTRACT The Bureau of Mines investigated a hydrometallurgical procedure to re­ cover gold, silver, and byproduct lead from a complex lead-zinc sulfide ore.

A hydrometallurgical test involving ferric chloride leaching of galena concentrates, purification of the resulting solution and direct electrolysis of thepud3ed leadchloride solution was performed in the Minemet Research Laboratory7. Lucas and Shimano8 have investigated two-stage ferric chloride leaching of a pyritic Zn-Pb-Cu-Ag bulk concentrate.

Recovery of lead and sulfur from galena concentrate, using a ferric sulfate leach. [Washington, D.C.]: U.S. Dept. of Interior, Bureau of Mines, [] (OCoLC) A hydrometallurgical process is used to recover lead from a lead-bearing ore concentrate. The lead-bearing ore concentrate is leached with a solution of cupric chloride in order to precipitate lead as lead chloride, produce elemental sulfur and substantially leave the balance of the ore concentrate sulfides in unreacted form. The residue of the cupric chloride leach is leached with a brine Cited by:

Ferric Chloride-brine Leaching of Galena Concentrate - Ebook written by Frank P. Haver, Morton Min Wong. Read this book using Google Play Books app. Note: Citations are based on reference standards. However, formatting rules can vary widely between applications and fields of interest or study.

The specific requirements or preferences of your reviewing publisher, classroom teacher, institution or organization should be applied. The US Bureau of Mines demonstrated ferric chloride leaching of galena concentrate on a continuous bench scale basis.

Leaching was performed at 95°C (°F) and with a contact time of 15 minutes. The ferric chloride leaching solution was continuously fed to a leaching tank Cited by: 2. Previous investigations of the ferric chloride brine leaching of galena concentrate have shown that additions of chloride ion result in accelerated dissolution rates.

The current study has provided the necessary information to extend and modify these previous results by incorporating the important effect of chloride ion on the dissolution simplicityhsd.com by: A new hydrometallurgical leaching process, which dissolves galena concentrates with acidified ferric fluosilicate solution, has been investigated for the selective extraction of lead and zinc from the galena concentrates.

The process of leaching galena concentrates avoids the generation of sulfur dioxide and lead dust emissions and is capable of treating complex sulfide and low-grade flotation Cited by: 2. Leaching Ferric Chloride. Because Wong extensively investigated extraction of lead from galena concentrates, only minimal effort was expended to investigate the FeCl3 leaching phase of the process.

However, because Wong’s work was with a high-grade galena concentrate (74 pct Pb), some research was conducted to obtain maximum silver chloridization. The leaching kinetics of galena-containing concentrate from Red Dog Mine (Teck) was studied with respect to variables such as stirring speed, temperature, concentrations of free acid and ferric ions as well as particle size.

It was found that stirring speed and acid concentration had no influence on the leaching Cited by: The leaching kinetics of galena-containing concentrate from Red Dog Mine (Teck) was studied with respect to variables such as stirring speed, temperature, concentrations of free acid and ferric ions as well as particle size.

The first step involved an oxidizing leach of the galena concentrate with ferric methanesulfonate solution. At the end of leaching process, the leach slurry was subjected to a solid–liquid separation process (i.e. thickening, filtration) with incorporation of washing in order to give a first solid residue and an impure simplicityhsd.com by: The leaching of lead from galena in acidic hydrogen peroxide in presence of sodium chloride solution has been investigated with respect to the effects of hydrochloric acid and hydrogen peroxide concentrations, by changing the stirring speed, leaching temperature and the particle size.

Galena concentrate has also been successfully leached in ferric chloride-brine solution [23]. The study shows that usage of ferric chloride-brine as leachants has a lot of advantages which includes having a greater potential for the treatment of complex sulfides, easy regeneration by.

the galena leaching rate to decrease rapidly. A minimum leaching rate was realized in saturated PbCl2 solutions (Dutrizac, ). Studies(Dutrizac, ) on the ferric chloride brine leaching of galena concentrate have been carried out.

The procedure involves leaching galena flotation concentrates with ferric chloride (fecl3) solution to obtain lead chloride (pbcl2) and elemental sulfur as expressed by the following chemical reaction: pbs + 2fecl3 -> pbcl2 + 2fecl2 + s deg.

At deg c, over 99 pct of the pbs in the concentrate is converted to pbcl2 in less than 15 min. leaching galena concentrates in waste fluosilicic acid (H 2 SiF 6) with Galena Concentrate Using a Ferric Sulfate Leach.

In this process, galena concentrate is leached at deg. F with a ferric chloride-brine solution to extract lead while leaving sulfur in the residue, which is discarded. The solution after leaching is concentrated and cooled to deg f by vacuum.
