Silicification can be divided into two stages (Ⅱ,III). Stage Ⅱ silicification is developed in the form of quartz veins or massive quartz. The quartz is smoky gray or grayish white, which is closely gold ore-related. Stage III usually develops quartz veins. The quartz grains are coarse and white, and are not gold ore-related.

The above pre-treatment stages can be changed based on ore mineralogy. For a complex Au–Ag ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µm.Diagnostic leaching was carried out to assess the nature of refractoriness [29].Depending on the results of the diagnostic test results, extraction strategies …

Chapman flux is just a house flux blend, a general or basic flux mix with most of the general ingredients needed as a general flux (basic minimum ingredients), which may work on a few materials but generally will need adjustment of added flux ingredients of oxidizer, reducer, or acid or basic flux in to build a recipe that will work with different types of ore,

Crush these smaller pieces up until you have a dust of quartz and gold mixed together.

Gold in quartz is sometimes classified as a collector's item and even a museum piece, but most is gold ore and the price is dependent on the amount of gold in the specimen or sample. Specific gravity tests are used to determine the gold percentage and, because of the amount of testing and eventual processing and refinement necessary, the ...
