Requirements for a clean technology in small scale gold mining (3)
A ton of low-grade gold ore may only yield on average 6.5 grams of gold – however the high value of the gold still makes the operation worthwhile. After the rock containing the gold has been mined, it is crushed to grains the size of sand. Next, gold is extracted from the crushed rock using a multi-stage process.

Once you find gold in quartz ore, you can extract gold by the flowing steps: 1 Use a sledgehammer to break the rock into smaller pieces. 2 Place a steel anvil in a large pan to prevent the loss of the gold contained in the quartz stone. 3 Look for large pieces of gold that can be collected manually or with tweezers.

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

The ore is sent into a single-cylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multi-cylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding.

For small pieces of quartz that contain visible gold, a simple hand operated crusher will do just fine. Many miners call these “dolly pots” and they are simply a mortar/pestle made from steel that you can put small ore samples into and crush up. You can buy one or have one made very easily.
