I have scrap gold chains, gold ring, many old cell phones, including sim cards, some computer motherboards I like to process to extract the gold & silver. But I dont have the space, means or time to do this myself. Question: is there any place who will extract it and melt gold/ silver extracted into bars for a few. Would it b worth time. Thanks

Raw gold has a smooth, but bumpy texture, caused as the gold tumbles through rivers and streams. When you set it in your palm, and set a rock of equal size next to it, the real gold feels substantially heavier. Flakes of fool''s gold – iron pyrite – break apart easily when you thrust a fingernail through it in the gold pan.

Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start.

Finally, once the rock is fully crushed we get to the part about separating out the gold from the crushed rock. Often, this is accomplished simply by very careful panning. Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds. On the other hand if you are going to be processing large quantities

In modern times though, mining for gold is a much more intensive, yet sophisticated process. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today. It’s largely a matter of technology and requires much expertise and elaborate equipment. Mining for gold today can essentially be broken down into 9

Today, gold is extracted in hardrock mines that directly mine the source rock, or "lode" of gold, where it was originally deposited by geochemical processes. Most ore accessed this way today contains only microscopic grains of gold, and it takes tons of rock to produce ounces of gold.

Prospecting for gold can be a fun hobby, though it’s a lot of work! You may be able to harvest gold flakes from rock if it contains gold among its minerals. The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you’re able to obtain some, though this is dangerous.

Step 1: Extracting Gold From Scraps. Collect any gold-containing metal scraps to which you have access, including jewelry, computer processors, old telephone wiring or gold tooth crowns. Keep in mind that outdated electronics are likelier to produce parts with a high enough level of gold to make the procedure worthwhile.
