911MPE has small gold mining equipment for sale and more specifically mineral processing equipment. Our equipment is best used in small scale extractive metallurgy operations operated by small miners or hobbyist prospectors and mining fanatics. 911MPE offers gold mining equipment as well as processing equipment applicable to most base metals such as copper, lead, and zinc.
Hydraulic mining was a potentially efficient method of getting gold out of the ground, but it was also the most environmentally destructive. The principle was very simple but devastating water under pressure would be directed against a bank of gravel deposits and the hillside would wash away rapidly.

Advances in numerical modeling, seismic monitoring, acoustic tomography, and rock mass characterization have contributed immensely to the evolution of modern, ground control design practices. Problems in mine design and rock engineering are complicated by the difficulties of characterizing rock and rock mass behavior, inhomogenity and anisotropy, fractures, in situ stresses, induced stress, and groundwater.
