· Blue clay gold ore generally contains a small amount of quartz, a large amount of gold, and a lot of black sand, and this type of gold ore is easy to identify. So If you find blue clay contains a lot of black sand, this may be a very good sign that gold is also nearby. Alluvial gold is most found in blue clay and is in clayladen gravel or between thin layers of rock.

· · Gold Cradle or Rocker Box. The Cradle or Rocker was introduced in California soon after the first rush to the diggings took place in 1849. It consists of a rectangular wooden box, about 3 feet long and 18 inches wide, resting on two rockers (D, Fig. 6) similar to those used for infants' cradles. The shape of the walls is shown in Fig. 6 ...
Separating the gold from the crushed ore proved to be a problem. Due to contaminants, older methods were ineffective. A technique using chlorine gas was adequate but not satisfactory. Eventually a process called cyanidation was commonly used. It was based on the chemical attraction of gold to sodium cyanide. The process would result in a "sponge" of gold and cyanide. The "sponge" would ...

A gold mine in Yunan, capacity was 300t/d; the main mineral was pyrite; fine granularity of gold; the gold had close relationship with metal sulfide mineral. This plant adopted the flotation processone roughing, two cleaning and two scavenging. But due to surface oxidation of arsenic antimony mineral, it adsorbed amount of flotation reagents, and the flotation effect was poor. So the plant ...

· A power rocker operated by two men can process 1 to 3 cubic yards of material per hour. The rocker is an improvement over the gold pan, but is limited by the need for frequent cleanups and poor fine gold recovery. Rockers are not widely used today. Gold Cradle. At least twice as much gravel can be worked per day with the rocker as with the pan ...
process that is used to recover gold from lowgrade ore. The degree of purity of native gold, bullion (bars or ingots of unrefined gold), and refined gold is stated in terms of gold content. "Fineness" defines gold content in parts per thousand. For example, a gold nugget containing 885 .

In this process sediment or ore thought to contain gold is placed in a wide, curved pan along with water. The miner moves the pan in a series of motions designed to eject lighter sediments. The density of gold keeps it on the bottom of the pan as lighter material is ejected along with water. After a series of successful iterations have been completed, gold will be exposed on the bottom of the ...
