Longwall mining involves cutting long tunnels into a coal seam and removing the extracted coal by conveyor belt. As the miners and the machinery move along the seam, a hydraulic support system temporarily holds the rock ceiling in place. Today, both room and pillar and longwall mining are performed with very powerful mining machines, which rapidly cut coal from the face of coal seams.

This probably is the reason why thickening rates in the cyanide plant are sometimes appreciably reduced when an ore is being milled which has partially oxidized in the mine and
A coal preparation plant (CPP also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
Trommels are quite simple to build and work excellent when they are constructed properly. The come in all different sizes from small units that can be used efficiently by one or two prospectors using shovels all the way up to huge commercial mining operations feeding them with loaders. The trommel itself does not separate out the gold.

In solution mining, wells are erected over salt beds or domes (deposits of salt forced up out of the earth by tectonic pressure) and water is injected to dissolve the salt. Then the salt solution, or brine, is pumped out and taken to a plant for evaporation. At the plant, the brine is treated to remove minerals and pumped into vacuum pans, sealed containers in which the brine is boiled and

How Placer Mining Works. Placer gold is recovered when the gravels are "sluiced" or washed in flowing water in a sluice box or wash plant. The heaviest particles, including gold, settle to the bottom. Many placer deposits are covered by frozen layers of sediments. Water is used to thaw these frozen materials and at the same time to wash the
