Using Borax Flux to Refine Gold MGS Precious Metals Blog

Using Borax Flux to Refine Gold MGS Precious Metals Blog

+

Aug 07, 2013· With some borax, heat, and a little knowhow, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

The world's gold production has changed over the past 30 years. The exploration and discovery of large, freemilling gold deposits in major mining districts has declined. Mining companies face a difficult decision. Do they process large, lowgrade deposits or look for smaller, often more complex ones in remote, often hardtoreach locations?

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
