For large and medium-sized cyanide gold extraction plants, the tailings can be alkaline chlorination or acid chloride. For example, cyanide tailings from a gold mine in Hebei Province, using lime added, chlorine gas under alkaline conditions (pH 9 ~ 11), tail slag after 2h purification treatment, ca
Wenyu gold ore deposits in accordance with its conditions, using a comprehensive Shrinkage mining method, and achieved good technical and economic results. First, mining technical conditions It is filled with the deposit account of epithermal gold sulphides quartz vein type, in addition to gold,
Where finely ground using conventional methods can not effectively extract most of the gold ore called refractory gold ore. The most common reasons why gold ore is difficult to handle are: 1) fine submicroscopic gold or gold was present in the state of wrapping or disseminated sulphide minerals, u
( 1 ) Registration application for mining rights; ( 2 ) Legal person business license or sole proprietorship or partnership business license during the validity period (if the mine affiliated to the legal entity has to provide the legal person business license and the mine business license); (3)
Many acid and alkali leaching of oxides obey the shrinkage core model. A typical example is the dissolution of zinc calcine in dilute acid. It is calculated using equations (1) and (2) according to the ion diffusion coefficient and ion mobility of each chemical involved in the dissolution process.
The present invention is a method for extracting gold from gold-containing mass. In the invention, the activated carbon fiber is contacted with various concentrations of the gold-containing solution to adsorb gold, and after contacting for a period of time, the adsorbent material is separated from
