A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. The Kimberley Big Hole is an example of openpit mining. In underground mining, miners tunnel through Earth's crust to the kimberlite pipe ...

The main problem for individuals or small groups interested in hard rock gold deposits is the high capital costs both for the mining equipment to dig and remove the rock as well as the equipment to crush and process hard rock ore in order to extract the gold from its solid rock enclosure.
This rock crusher does a fine job. It will crush small 2 in. X 2in. rocks into dust in a matter of a minute. Although very small pieces of rock remain intact, they are small enough to either use a pestle and mortar to pulverize them or leave them as they are and pan them separately You certainly will be able to recognize any possible gold still trapped within them..

Rock Systems offers two types of crushing chambers: compression crushing, which squeezes the rock under great pressure; and impact crushing, which throws the rock at a high speed at stationary anvils or curtains to fracture the rock.
Mining accidents occur in the process of mining metals or minerals. Thousands of miners die from mining accidents each year, especially in the process of coal mining and hard rock mining. Generally speaking, surface mining usually is less hazardous than underground mining.
Hard rock mining, placer mining, by product mining and gold ore processing are some methods of gold mining. Each method has its unique process of accessing, extracting and processing gold. Hard rock mining is a method that involves the creation of underground tunnels or open pit mines to access gold in a surrounding rock. Consult
