· Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.

· Gold ore does not usually have any shiny gold on the surface. Spotting it with the untrained eye does not always yield results; it''s better to try a jeweler''s loupe. Then it is possible to see flecks of gold sometimes. It is usually not possible to find gold ore with a metal detector.

· A somewhat similar experience occurred at the Mt Gibson gold plant, which was designed to process laterite ore, which overlaid deeper mixed oxide–sulfide ore. The ore contained about 500 g/t cyanide-soluble copper, some of which was associated with sulfide mineralization and which occurred within highly weathered clay minerals.
· Cyanidation process has been the key element in the processing of gold ore. Over the years steady improvements have occurred in equipment design; milling has evolved from stamp mills, through tube mills and ball mills, to the large semi-autogenous grinding (SAG) and fullyautogenous grinding (FAG) circuits in modern gold plants.
The oxide ore will be processed using conventional heap leaching technology, and the sulphide ore will be processed in the existing concentrator after some modifications. SURUCA SULPHIDE ORE Suruca sulphide ore is currently being planned to be processed through the existing Chapada plant, with some modifications, at the end of the Chapada mine life.

· Changes in ore properties, such as ore gold distribution and hardness have influence in gold liberation and consequently will be affected the recovery process. For example, orebodies containing clays have problems due to the excessive amount of fine material liberated during the comminution process due to rheological and physiochemical properties are modified.
