Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth''s crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silies, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.
In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classifiion (separation by particle size) either for further grinding or the next step, concentration of the ore.
