minerals mined by adit ore dressing method

Kelly Mine

In 1892 the mine was advertised for let by J. Dadd of Kelly and was stated to contain several valuable lodes and to be equipped with a waterwheel and stamps for ore-dressing. Up to 1900 the mine appears to have remained idle, until the Scottish Silvoid Company of Glasgow took over the lease with Mr. A.W. Govan as manager and Mr. Hill

New Idria – Explore Real California Gold Mines!

Mercury mining began in New Idria in 1854 after the discovery of huge mercury bearing cinnabar deposits. In fact tons of the red ore can still be found scattered about the area. The large quantities of mercury used for gold recovery during the gold rush made New Idria one of the countries most productive mines.

Tungsten MiningBeneficiation

Mining methods for tungsten ore are not at all exceptional and usually are adapted to the geology of the ore deposit. Most tungsten ores contain less than 1.5% WO 3 and frequently only a few tenths of a percent. On the other hand, ore concentrates traded internationally require 65-75% WO 3. Therefore, a very high amount of gangue material must
