Underground mining of placer deposits (drift mining) and of hardrock gold-quartz vein deposits produced most of California''s gold from the mid-1880s to the 1930s. Another important source of gold from the late 1890s to the 1960s was gold-bearing sediment, which was mined using dredging methods.

The process of separating gold from quartz is complex and involves the use of expensive nachinery and nothing of im-portance can be done with even a rich vein until such machinery is provided. Another important fact is that a quartz vein is not always, nor usually, gold bearing.

Refractory Gold. The last type of gold deposit is called refractory gold, and it is the most difficult type to extract. It can be defined as any ore that responds poorly to a conventional gravity-cyanidation process with examples including copper porphyry, complex sulfides, arsenopyrite and lead-zinc associations.

The miners followed the veins and blasted the gold from the quartz. The mineshafts and drifts were then “mucked out” and the gold-bearing ore was transported to the surface for processing. To access the gold, the ore had to be crushed. The first crushing equipment was the Mexican arrastra, a device that ground the ore between two stone

Gold-bearing quartz reefs have been the source of much of the gold recovered throughout the world from Roman times until the present day. By about 1900 the processing of quartz ore had become standardised, consisting of several steps: 1. Crushing to release the gold (and any other minerals); 2.

I''m thinking that if you''re getting 100- or finer gold, don''t go above 1/2 inch down from the top. Coarser material can have more material put in the bowl. 100-, only about a rounded tablespoon full. Hope this all helps. Google the blue bowl and you''ll probably find a vendor with the full instructions online.

Answer (1 of 12): No they do not. Quartz is common, gold is rare. Quartz veins typically form when very hot water rising from depth flows into a shallow crack in the rock. The dissolved silica precipitates as quartz. If there is gold present in the water, it will also precipitate. The result is

Gold in quartz veins occurs as particles and scales scattered through the quartz, often filling cracks and openings in the vein material. The gold can be such small particles as to be invisible to the naked eye, or as larger aggregates of easy to see blobs, leaves and crystals in cavities in the quartz.

1. Gold Processing. The first step in gold smelting involves processing the gold ore. The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore together. The gold ore is then pulverized using pressure to create very fine particles.

For the average prospector, this large equipment is likely too expensive and is also not necessary for processing small samples of high-grade gold in quartz. For small pieces of quartz that contain visible gold, a simple hand operated crusher will do just fine. Many miners call these “dolly pots” and they are simply a mortar/pestle made

The quartz gold combo in streams gets me a little more excited than in rivers but the method of back tracking doesn’t change. I will just come out and say it; “you need to go up river and find the outcropping of quartz where the gold vein comes from”. However, if this quartz is in the rivers bedrock you will probably never find it.

Answer: All gold-bearing quartz was initially what we call a supercritical fluid, which is a fancy way of saying it’s so hot that it wants to be a gas, but it’s so pressurized that it wants to condense into a liquid.
