— Thank you Reno for your response. The lab did perform several assays on various samples I provided to them from around the property. They used an assay process, to quote their report, "With respect to the analysis, the samples of head ore, the concentrates and the tailings were treated by a procedure partially developed by the …

 — Treating ore with chlorination metallurgy is a kind of metallurgical process of comprehensive recovery and utilization of ore resources by means of chlorination metallurgy.

 — Heres a chlorine leach for you. CaCl2 + CaOClH + H2SO4, this is from the textbook on the metallurgy of gold and was used in lead lined vats to generate chlorine and to leach ores. Also, just a note, most pool chlorine is not calcium hypochlorite anymore, make sure you check what you are using. Jim

 — Hello Everyone! I am so glad I have found this forum! I have been trying without much success to make an educated decision on what do with some ore that I believe is silver. It is located on a private ranch owned by my father. For years I have enjoyed exploring, rock hounding, and spending...

Silver refining has been used from ancient times to change the characteristics of the metal. Early metallurgists refined silver by heating it a couple hundred degrees above its …

 — By the middle of the 19th century, people tried to use chlorine gas to treat gold ore, which was the first application of chlorine gas as a gaseous chlorination agent in chlorination metallurgy. At the same time, chlorination metallurgy has been gradually expanded to treat low-grade copper ore and pyrite cinder.

In using chlorine to extract ...

 — Refining: After the silver ore is processed, the extracted silver may need to undergo further refining to remove impurities and obtain high-quality silver. Refining methods may include smelting, …

With the Silver Chloride (AgCl) method, Silver can be refined in a batch-wise process to a very high degree of purity (999-9999) with relatively "simple tools" and easy to source chemicals.A disadvantage of this process is the large amounts (relatively) of waste solutions produced.Silver scrap is first dissolved into solution using a 50:50 mix of Nitric Acid 67% …

 — Illustrations of hydrometallurgical processing of silver-bearing inputs will be provided by the treatment of sulfated silver-bearing materials and chlorinated slimes. The first of these technologies will be described briefly as practiced by the Phelps Dodge Refining Corporation for several years.

 — Silver Refining and Recovery - emewCorporation. Silver refining is typically the final process in the production of high purity silver suitable for sale in the market. It is associated with purity and typically needs to meet a minimum of 99.9% purity and in most cases 99.99% purity and in some cases 99.999% purity depending on the end-use.

 — We are leaching ore with HCl/Cl with fairly good results. Now we need to recovery the dissolved metal. We are currently using resin beads. Just wondering if anyone has any experience to add. We are planning on rinsing loaded beads with borohydride to change PGM's to neutral state while still on...

 — Im new to this but Im trying to leach ore with chlorine and hci. My ore has been assayed at 2+ O/T. I have crushed it and ran it over a RP-4 table and have panned it also with no visible gold. Would like to know a possible mix using bleach or swimming pool chlorine. And if you can use sodium bisulfate to take the gold solution back to a powder.

Gold processing - Refining, Smelting, Purifying: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in …

 — Roasting sulfide is a must, adding iron (like nails) to the roast can help to convert the sulfides and drive off the sulfide as SO2 gas, sulfide can lock up you're gold in the ore keeping a leach from getting to it. sulfide can be handy when concentrating the ore as they like to float in a froth of air and oil, but for leaching sulfides are trouble.

 — 1. Collect known high grade hard rock Au ore (proved by assaying), especially from old mine dumps. 2. Crush up this material and roast the ore. 3. Load up a small container or bucket with the material and pass chlorine gas through the lot. 4. Extract the AuCl and drop the gold out with SMB. Is this possible?, can it be experimented on a …

 — Gold or silver mines use ore-processing technologies using various techniques with an alloy composed of gold-silver which is known as Dore bar ... The Dore bar then undergoes a chlorine refining process known as "Miller process". ... Gold-silver refining processes are mainly responsible for human toxicity (cancer and non-cancer) …

 — Use a stirrer to keep the ore agitated in the leach solution, a magnetic stirrer or a plastic overhead stirrer are good. Understand that chlorine gas will be evolved in the leaching process, do the leaching in a fume cupboard or standing upwind outdoors. Also understand that chlorine is nasty enough to be declared as a banned agent in war.

 — The process involves passing current through a brine-pulp to generate chlorine at the anode and base at the cathode. The chlorine and base combine to form …

 — Cooler temperature will keep more chlorine gas in solution, while heat can assist in how fast the reaction proceeds (two-edged sword). bubbling chlorine gas would not form sodium salts and increased acid consumption as would the bleach with its sodium hydroxide component to make it basic and to keep the chlorine gas dissolved in the water.

 — The term refining has been very often applied to the removal of base metals from the noble ones, or, in other words, separating the oxidizable from the non-oxidizable ones. When used in this sense it is …
