It is the underground hard rock mining business that has transformed California gold mining into an enterprise activity. It was the northern mines that gathered around the Grass Valley that dominated the initial underground mining industry. Gold bearing quartz is extracted from underground veins by intense, weak sweat and blood.
From the 1860s to the beginning of the 20th century, hundreds of hydraulic placers were operating in California, especially in the northern Nevada mountains. Figure 6.

Overview of flotation equipment for gold mining in early 1900 the first gold mining tools in the United States were very simple knives. Throughout the history of dredging in California, there were more dredgers floating in Oroville. Dredging has been the main method of gold mining in California since 1900, which allows the excavation of equipment moving along the incision.
At the beginning of 1900, gold flotation equipment was used. Gulin production line was composed of more than 30 machines, which set a standard for our industry.

In the early 1930s, with the introduction of water-soluble flotation collectors (especially xanthate and sodium dithiophosphate collectors), the gold mining industry began to use flotation on a reasonable scale. These collectors allowed differential flotation of sulfide minerals, and then pyrite flotation devices were installed in the gold industry.
