gold ore smelting flux


2019-10-14 · Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnace....

Assaying and Smelting

For example, If we are assaying a sample of ore for gold we must first divide all the ore as well as possible by grinding it. Usually, 30 grams of this ore is mixed with the flux. The flux is composed of a calculated amount of silica (white sand), lead oxide (red lead or litharge), sodium carbonate (washing soda), and flour, cornmeal, or

Fill a container with 30ml of nitric acid for every ounce of gold you're working on. Activate the solder tool and place it on the gold. Raise the solder temperature on the gold up to 710 degrees but less than 780 degrees to effect melting. Pour the melted gold into the container with the nitric acid. Wait for 30 minutes for the mixture to interact....

Using Borax Flux to Refine Gold

In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little know-how, 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.
