Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead. It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies.

Hard rock mining operations can vary widely depending on the nature of the deposit and require varying degrees of ground support to provide a safe working environment. Blasting and seismic loading can create additional hazards for the rock mechanics engineer who must design an effective support system for these conditions.

The kind of equipment you might consider for crushing and processing your ore depends greatly on the nature of your ore, your budget, and the amount of rock you have to process. The difficulty with recovering free gold from hard rock ores has always been the cost of constructing a mill and operating it.

Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or sub-surface mining techniques are used. Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes.

First I used some crushed gold ore from a working hard-rock gold mine, just to see how well the sluice would catch gold. I ran the crushed ore through the sluice and then did a cleanup. The 3rd photo below shows the results after panning out the material left in the sluice. It caught a lot of gold, but did it catch all of it? That was the big

Mostly, the gold obtained through gold electrolysis is usually very pure, almost 99.999%. In fact, this procedure is the best method for processing gold with the highest karatage (24 Karats = 100 percent gold). This is why gold electrolysis is very common in countries where pure gold pieces are given priority over the ones with low karatage.
