Unlike alluvial gold, which is found as very small flakes on riverbanks, gold-bearing rocks have to be dug out of the ground. We''re after pure gold, but rock that contains gold also includes lots

The process of gold ore processing and production mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for high-hardness gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;

Using a heavy metal, smash the crushed rocks further until it is in the form of a powder. Ensure that the result is finer than sand. This process helps in getting all the gold from the rocks. The amalgamation process then helps in separating gold from the rock by adding mercury to the finely powdered rock-gold.

One of the earliest methods for extracting gold, salt cementation, was perfected by the Lydian Empire during the Iron Age. Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover.

The average miner can instead purchase a CrazyCrusher manual rock crusher or an electric or gas powered rock crusher and get the gold out in smaller batches. Crushing rock to recover gold can be easier, faster, and much more profitable than prospecting in over-worked streams and rivers.

Put the rock powder in a mining pan. A mining pan has holes in the bottom of it like a colander. Because gold is heavy, it will sink to the bottom of the mining pan even while it''s submerged in water, while the other minerals wash away. Pour a layer of rock powder onto the mining pan so you can extract the gold pieces.

Free gold is the portion that is easily removed without the use of complex chemical procedures. Miners have been extracting free gold from hard rock sources for thousands of years. It simply requires that the ore be crushed and broken apart enough that the gold can be separated from the host material.

Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation.

The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
