·As you proceed pick out the separate pieces of gold Run the material through the sieve Return particles that do not go through the sieve back to the mortar and pestle and Grind them until they fit through the sieve Place all the powder that fit through the sieve into your gold pan Use the gold panning method to separate the quartz and gold

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 gold combine with
Gold panning is an exciting and rewarding hobby but it can be frustrating when you come across black sand Black sand is a mixture of materials including iron and other heavy minerals that can make it difficult to separate the gold from the rest of the sediment
This causes gold to collect on the negative terminals Smelting which results in nearly pure gold involves melting the negative terminals in a furnace at about 2 100 degrees F 1 149 degrees C When workers add a chemical mixture known as flux to the molten material the gold separates from the metal used to make the terminals Workers

·No matter which crushing system you re using the process will go far faster and come out better if you do repeated screenings of the material from time to time What happens in crushing is that some of the material gets crushed down to the size you want but other pieces don t Dore is a term for unrefined impure gold and silver metal
Another precaution that frequent gold smelters often practice is having a separate area in which to perform the process such as a workbench or shed a few feet from the house There are electric furnaces available online that are designed specifically for melting precious metals such as gold and silver These allow people to mix metals
You Will Need Mildly abrasive pad Scotch Brite Felt cloth; Tripoli Compound; Jeweler s rouge; Silver polish; Soft cloths; Steps to Remove the Gold Plating Begin by using a mildly abrasive pad to remove as much of the gold as possible Hold the piece carefully and apply some pressure as you move the pad back and forth across the gold plating
