Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.
NaCN 8hrs. However, gold recovery above 85% was achieved by leaching in 600g/t NaCN for 8 hrs.

8 Methods to Extract Gold. The gold beneficiation process of easy to separate gold ore consists of amalgamation, gravity separation, flotation, and cyanide. The choice of the extraction processing method depends on the nature of the ore and the requirements of the product form. The commonly used beneficiation flow as following.
This type of SSGM involves several subprocesses: (1) tunneling, (2) ball milling and gravity concentration, (3) cyanide leaching, and (4) smelting. First, tunneling involves digging a pathway or tunnel into the rock or earth under which the gold ore is believed to be located. The gold ore usually runs through the earth in veinlike formations.

Gold mining is the extraction of gold by mining . Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. The expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation.
