Mar 15, 2019 Wow Gary! My local jeweler offered me $2200 for my 22-karat gold so I took a chance and mailed it off to you on Tuesday 10/30. Today—Monday—less than a week later there’s a check in my mailbox for $4366. I am very happy with your service and I will use you again. Thank you! Sally, CA
Our gold refining process begins when we receive your scrap gold (or other precious metals) to be recycled. To determine the metal’s purity, we perform an assay. Once we have assayed the weight and purity of the gold, we have all the information we need to quote you a payout price. From there, your gold is melted down in our refinery

Our ore assay lab performs fire assays for gold and silver ores, testing daily for precious metals in trace amounts up to high grade ores and concentrates, continuously since 1954. We test all types of ores and minerals. Tests include Spectrographic Analysis for most metals and fire assays for gold and silver ores, platinum minerals
Secondly, you have to put your gold through a testing process to see how pure it is . . . this testing process is called “assaying” your gold. Gold that is in the raw form of flakes, nuggets or dust will always have impurities, and you need to find out exactly how pure your panned or prospected gold really is
Oct 20, 2009 1850 is below the melting point of gold. Even if the temperature goes above 1850 the vapor pressure of gold is small, so very little is lost. H2O, for example, has vapor pressure 6 orders of magnitude higher. Small particles of gold float on the surface of water so they float on the slag. This ignores the process that goes on
Apr 21, 2020 Royalty companies are different from miners. Royalty companies control hundreds of thousands… even millions… of ounces of gold in the ground through legal contracts. They have a claim on a small percentage, usually 1% or 2%, of that miner’s production – regardless of how hard or costly it is to dig the ore out of the ground
grade copper ore may be only one quarter of one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called

From ore to dor . More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore
It is a high technological enterprise that integrated research , manufacture, sales and service . The company has multiple subsidiaries such as Mineral Processing Research Institute
We Process Black Sands. Due to the heavy iron content of black sands, most processors, smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content
A sample is removed for assaying, which is the process of measuring the gold content. Assaying is critical for assuring customers who sell gold scrap to us that we fairly compensate our customers. For maximum accuracy, we use the Fire Assay and Inductively Coupled
For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton. This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let’s assume that gold is valued at $1500 per
May 22, 2018 You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off
That's because the process is problematic if the piece is less than 24k gold. Other karats of gold, such as 14k or 18k, are not 100% gold; the gold is mixed with other metals. Each of those metals have a different melting point and behave differently, which makes for unpredictable results
Jul 21, 2021 The gold mining operation at Carlin is the largest in the world, with a massive ore body that has yielded millions of ounces of gold over its more than 60-year history in northeastern Nevada
