The cyanidation tests after ultrafine grinding showed that the recoveries of gold and silver were enhanced by 26% and 18%, respectively. Ultrafine grinding process prior to cyanidation could be, therefore, used as a physical pretreatment method to improve the cyanide leaching of gold and silver from the antimonial refractory ore.
Know Where to Look for Gold. Some prospectors like to work the drainage systems and hillsides in the Tonto Basin, west of State Highway 87, in the northwestern corner of Gila County. Others take to the stream beds in the Lynx Creek area, a few miles south of Prescott, in the heart of Yavapai County.
The product from the grinding circuit goes through a size classifier ( vibrating screens, hydrocyclones) to ensure that it is fine enough to liberate as much gold as economically possible, typically 60 to 80% finer than 200 mesh (74 microns). The ground ore and mill water (pulp), is leached by mechanically agitating it in a series of tanks.
