Gold flotation is widely used in the case of refractory ores, in which small-sized gold particles, locked within sulfide minerals, are recovered through flotation of gold-bearing minerals (Marsden and House, 2006). It is also an effective means for separating free gold from silicate particles present in ore.

The miller table is a gold separation device that consists of a flat sheet of matting inside a sluice, with water flowing over it. The black sand concentrate is dispersed gently at the start of the matting. The lighter black sand is then pushed down the matting, while the heavier gold stays where it is and can be collected. ...

This causes gold to collect on the negative terminals. Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers ...

In over 80 developing countries in the world, mercury is the artisanal gold miner's go-to for separating gold from concentrated ore. Due to a lack of resources and available alternatives, mercury is often handled with bare hands, and in the effort to amalgamate gold, much of it escapes into waterways and soil where it enters the food chain.

Riffles separate heavy and light particles. Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening. Some experienced operators have ...

Step 6. Shake to Reveal the Gold. When the mining pan is fully submerged, shake it until you see the gold resting at the pan's bottom. While you do this, you will see the other particles start to drift away from the pan, mixing with the water. This makes it easy to see the gold better. Lift the pan out and remove any clear gold piece you see.
