"How To Refine Precious Metals" - You Can Read It for Free With Kindle Unlimited!


I'm grateful for all of our hard working team of employees who busted their butts for the business and not just a paycheck. Their hard work, loyalty and enthusiasm was a great inspiration for me.  

We started out with 3 of us in the garage and grew to around 27- 30  employees in a building just outside of town in Modesto, CA in a little over a year and a half.

Our business was in it's infancy as a  manufacturer of very simple silver charms. We started in our garage in a rented home in Modesto, California.
My father traveled all over the country building relationships with buyers and sellers while my girlfriend and I worked about 16 hours a day - 7 days a week manufacturing the silver and gold charms using the lost wax casting process. This lasted a year until our garage was full of employees and we had to move into a commercial building near the edge of town. In the next few months we rapidly grew to casting up to 72 - 4 X 6 inch flasks 2 to 3 days a week which  would produce about 3,8880 small charms. The process creating a great deal of polishing dusts, floor sweeps and grindings which we eventually decided to refine ourselves. In the beginning I tried to follow instructions from what we were able to read and repeatedly failed to achieve the purity and complete return of precious metals from our scrap. Finally my father decided to hire a professional refiner and a chemist to help us get everything going properly. The information found in this blog are the exact processes that we developed with the help of 2 refiners, 2 chemists and a PhD metallurgist. 

I hope this becomes a valuable reference for you and sparks your entrepreneurial spirit...continue reading by

Back In the Day - Operating Gold and Silver Refineries



I was born in Alaska and I grew up in Central California.
Over 33 Years Ago I trained with and helped to manage "The Phoenix Company" in Modesto California a Jewelry Charm manufacturing company that evolved into a Commercial Gold and Silver Refinery - The Phoenix Smelting and Refining Co.


My father and I built the jewelry charm manufacturing company, (The Phoenix Co.) with the help of my girlfriend and we worked about 16 hours a day in the garage then soon expanded to the outskirts of town growing our business to 30 employees. We worked our butts off for a year before we finally became well recognized as a  wholesale jewelry manufacturing company located in Modesto, CA USA. Our business grew rapidly and soon we needed to recover all of the gold and silver from our floor sweeps, grindings and polishing dusts. We then hired chemists and metallurgists to train us in assaying , smelting, recovery and refining.

At this time we learned about a company through a refiner in Oregon that manufactured heat processing equipment. We contacted them with a proposal for the construction of a furnace that would reduce x-ray film to ash without losing silver at high temperatures.
They put their team of top engineers in the industry to work on it and with our combined ideas and the help of a German scientist designed a machine that would recover silver from pre 1980's X-ray film at a capacity of 500 pounds of film per hour producing an end product of approximately 100 Troy Ounces of 99.99% Pure Silver per Hour with only trace silver losses due to volatilizing. The company that helped us design and build the Pyrolysis Machine is Kleen Air USA. The process which is used widely today is more commonly referred to as Bio-Mass Reduction.  


Our gold and jewelry charm company production rose and fell with the gold and silver prices rising to their highest prices in history up to 1980. Gold refining became more lucrative when Gold peaked in 1980 then prices took a downturn which led us to selling the jewelry/refining companies at a good exit point for our situation. We then moved to Hong Kong, (http://www.companies-hongkong.com/jkl-industries-h-k-limited-3myw/ ) where we built rotating cathode electro winning, (reverse electroplating), units for hospitals and plating shops. These units recovered silver from fixer solutions utilized in X-ray film production and gold from cyanide solutions used in gold plating operations. Later we moved to Thailand where we exported jewelry for about a year. Then my father and his lovely Thai wife started a boat building business in Terrenganu, Malaysia and went on to operating a resort on Kenyir Lake in Kuala Terengganu. As organizing chairman of the local Lions Club dad was able to organize fun trips for orphans and children of single parents. The two of them continued to operate the resort for 8 yrs. until his health issues forced them to return to the U.S. I came back to California and went to work in the technical metal alloys industry producing technical brazing alloys for medical, automotive, aircraft and other highly specialized purposes.

  I am currently living in Oregon USA and I interested about helping you if you are serious about starting a gold or silver refinery and partnering with you or providing you with consultation. I can't provide all of the knowledge that would be required to start this kind of business with  continuously changing City, County, State, Federal industrial, environmental, employee, etc. regulations. As with starting any business you have to employ specialists as needed. But I can provide a smooth transition for you from your first "back yard" melting and pouring of a 3 gram button of silver or gold to your first 1000 troy Ounce Bar of .9995 Fine Silver or Gold.

You agree to do your research and accept full responsibility for your actions. If you agree to the statement above then continue reading and enjoy, if not we advise you to leave now or continue reading for learning only. I strongly recommend that you take a laboratory safety study course or lab safety class before proceeding with processes described in this book and do not work alone. I also suggest that you start with simple and basic refining methods before you attempt some of the more complicated ones. Also be easy on yourself, perfecting your skill comes with practice.

Preparing Scrap Gold for Refining
When precious metal bearing material is received from a customer it is weighed and copies of the gross weight received with the customer name and date, an order number, processing instructions and lot number are produced. Samples are taken and the material is sealed in a drum with a metal seal and identification. Processes for sampling vary depending on the material. Several samples are taken from the material. Samples are given to the customer, some are sent out for an independent assay analysis and some for your in house assay. In the case of raw metal it is melted, homogenized and poured into and ingot so drilling's can be taken as samples. If it is solutions you will need to draw liquid samples. If it is sweeps that must be incinerated it will have to go through a lengthy process that is described below. Before dissolving gold in aqua regia, (1 part nitric acid & 3 parts hydrochloric acid) make sure it is free from waxes, oils plastics, tar, any organic materials, sulfides, chemicals, etc. "Sweeps" material is often full of crushable materials like old broken crucibles, clay and glass as well as combustible materials like polishing dust, paper, waxes, common garbage and sometimes even food.

PGM REFINING

pg.14

If the gold contains platinum and palladium amounting to quantities that are profitably recoverable like some of the dental alloys, the gold is digested and the solution is evaporated to a syrup using evaporation dishes. A small amount of sulfuric acid is used to help prevent the acid from spattering when it has evaporated to a syrup. The thick syrup is diluted with 1:1 HCL and water and filtered if necessary.
Then before rinsing the filter paper, remove the filtrate from the filtering flask and place it in a clean container. Then rinse the chlorides in the filter paper 3 to 5 times with dilute, (10ml per liter) HNO3 to water. Evaporate this rinse filtrate down to a syrup or crystal and add it to the rest of the filtrate. This filtrate is evaporated again to a crystal and re-diluted with HCL ...continue reading by

Alloying Karat Gold

16


I like to use an accurate scale with an accuracy to .01 gram. Use pure metals and a clean melting crucible that has only been used for melting the same alloy. Use a consistent melting and stirring technique to provide repeatable results. For alloying gold you should have a supply of Pre-Made alloy ready to add to 24 karat gold for producing the lower karats.
For alloying silver to sterling, keep on hand a supply of pure copper.
The copper is melted, poured into shot and dried for later use. Be careful to dry completely to avoid weight variations and possible explosions when introduced into a melt.
Many alloy formulas for karat gold alloys can be found online and in jewelry manufacturing textbooks. A good alloy for making yellow gold of various karat content that I used to use is: 57% Copper 33% Silver and 10% Zinc. More sophisticated alloys containing silicon can be purchased from precious metal suppliers... Continue reading by clicking on the link below and purchasing

Pouring Gold and Silver Bars

20

Once you have added the alloy to the 24 karat gold you then
melt, flux, and stir the molten alloy using the procedure
mentioned previously. then pour the molten alloy into shot.
When you are ready to pour bars make sure the bar molds
are very clean. If you are going to pour into a graphite ingot
mold be sure to preheat the mold to drive off any moisture
it contains or the metal will explode when it contacts the mold.
Graphite molds will absorb water from the air so they have 
to be heated prior to pouring molten metal into them. Be
sure not to pour any boric acid or borax slag into the graphite
molds or it will stick to the mold and you will damage the
mold chipping it out... continue reading by clicking

Testing and Assaying Gold and Silver Pg. 22 - 36

Pg. 22 – 36

You need to assay scrap before refining to determine it's purchase value.

Customer lots are sometimes assayed to determine the exact value so that they can be combined and refined as one lot.

Test silver with nitric acid. The silver item is given a notch with a file before testing with the acid to determined if it is solid silver or only plated. Small acid bottles with ground glass stoppers can be purchased from laboratory supply companies.

One type of acid bottle has a lid which allows dispensing of one drop at a time. Another type has a glass rod which can run a streak of acid across the metal. It's important to know that there are a lot of types of silver markings and a lot of counterfeit silver passed around as well as legitimate names such as nickel silver and German silver which don't have any silver at all in their alloy. So it's important to develop the ability to recognize silver from various imitations and look-alikes. The same holds true for gold. You should develop the ability to see the difference in most cases. It's a good idea in the beginning to have small samples of other metals to comparewith gold and silver and to observe the way the acid reacts on the different metals. As far as scrap silver there are three common types you will run into. They are .750, .800, coin silver, ( 900 fine) and Sterling is .925 to .950.

23

Before using the acid be sure the metal you are testing does not have varnish, lacquer, was, or other substances on it's surface which will form a barrier for the acid to come into contact with the metal. Then place a drop of acid on the metal surface where you made the notch. Wait for the acid to react with the metal for a few seconds and observe the color of the acid...continue reading by
