At present, it is roughly estimated that there are gemstone mining operations in the Mogok Stone Tract. These range from individual artisanal miners, to cooperatives, independent miners, semimechanised operations to largescale mining companies working with modern excavators, drillblasting and exploration techniques.
In the beginning, the goldbearing quartz was wrenched from underground veins by backbreaking, dimly lit sweat and blood. However, imported miners from Cornwall and Wales adapted ancient European mining techniques and brought modern technology to the enterprise. The miners followed the veins and blasted the gold from the quartz.
For example, check side slopes of ridges which contain the ancient channel deposits, since these are areas that usually could not be exploited by hydraulic or groundsluicing mine methods, due to lack of adequate water or water pressure. These (unexploited) areas can produce eroded substantial pockets of placer gold.
These may be large enough to be exploited by modern mining and metallurgical techniques. The Carlin mine near Carlin, Nevada, produced gold from a large lowgrade deposit that was opened in 1965 after intensive scientific and technical work had been completed.

adapting computerimaging techniques, precision measurement systems, lasers, and other modern technological equipment, many manufacturers have improved their ability to cut gem diamonds in ways unimaginable only a few short years before. A significant result of this revolution is a diamond industry that is now better able to operate profitably.
The methods used by the Roman miners are described by Pliny the Elder in his work Naturalis Historia published in about 77 AD. The author was a Procurator in the region and so probably witnessed largescale hydraulic mining of the placer deposits there. He also added that the local lake Curacado had been heavily silted by the mining methods.
Most modern mining techniques have high water demands for extraction, processing, and waste disposal. Wastewater from these processes can pollute water sources nearby and deplete freshwater supplies in the region surrounding the mine. Some mines, such as the Mountain Pass mine in southern California, have implemented wastewater recycling ...

There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. Insitu mining ...
