stress, enabling the excavation of hard rock using a small, compact machine. "The undercutting effect leads to reduced cutting force requirement, while the activation, the application of momentum to break rock, leads to low pick wear and low resulting forces and allows the cutting machines to be light and mobile," Steinberg tells MM.
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.
amount of explosives required to break a unit measure of rock. Since rock is usually measured in pounds, there are several possible combinations that can express the powder factor. Powder Factor = Tons of rock (or cubic yards) per pounds of explosive. Normal range = 4 to 7 Shallow holes = 1 to 2 External loads = .3 Tons of Rock = Powder Factor
Gold Smelting Equipment It has been shown that concentrates obtained by gravity devices and cathodes can be smelted directly most the time. Silvergold concentrates can be smelted too. Under this consideration, a concentrate must contain at least 20 oz/t of gold. Obviously, if the higher grades are better and 50 oz/t is a good average value.
Highcapacity rock breaking. Capacities of between 200t and 400t per hour are typically achieved and higher numbers have been attained by some of Fractum's progressive customers. The Fractum breaker is the ideal solution for companies wanting to reduce the equipment required on site for demolition and rock breaking.

Hardrock (Lode) Mining. In both kinds of hardrock mining, the ore is then processed in some manner to remove the gold. Usually this entails crushing the rock into powder and using some combination of gravity, centrifugation, and "froth flotation" to perform an initial separation of gold from rock.
it to be removed with a conventional bit. These combined systems could yield a two to fourfold increase in drilling rates ().A similar system could be used to speed up the advance rate of tunnel boring machines (TBMs; Figure ).Cutting slots in the rock with a novel device weakens the rock and allows conventional cutters to break the rock into larger fragments ().
