ANALYSIS OF THE CONDITION OF COAL GRINDING

2013-2-26  One of the key subsystems in thermal power plants is the coal mill used to pulverize the coal before it gets into the plant furnace. The interior of the mill rotates and the plates located on the inside grind the coal into a small size powder. During that process the plates within the mill slowly get depleted and the productivity of the mill gradually de-creases until it becomes completely dysfunctional (Figure 1).

Eliminating Copper from Gold Ore 911 Metallurgist

2015-10-11  When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper

Treatment of copper-rich gold ore by cyanide leaching

2015-3-2  Ammoniacal cyanide leaching has been proposed for the treatment of gold ores that contain reactive copper in appreciable quantities [4,5,8,34]. Compared with the traditional cyanide leaching, ammonia cyanide system allows selective leaching of gold from copper-gold ores with remarkably reduced consumption of cyanide. It is a rather complex system intimately controlled by the reagent interactions within the system. Therefore, based on the preliminary studies [6,12], leaching tests were designed using Box-Behnken design to evaluate main and interaction effects of concentrations of NaCN, NH3 and Pb(NO3)2 on the selective extraction of gold and consumption of NaCN. Table 4 shows gold and copper extractions as well as NaCN consumption (kg/t per 1% Au) over 24 h. Figure 8 is also presented to illustrate the time-dependent leaching profile for gold
