In placer mining process gravity concentration methods which gold digger commonly used, perhaps can let you know more about the gold ore dressing. Gravity concentrate placer mining has generally been most widely applied. In a placer deposit, there has generally been a pre-concentration of gold made naturally by gravity concentration due to ore particles being transported by water. Mechanical concentration is used to continue the gold refinery process in Kuwait until sufficient concentration is obtained. Gravity concentration works when gold is in a free elemental state in particles large enough to allow mechanical concentration to occur.

In general,there are two kinds of flotation method in gold mining process.In recent years, the transformation process and pharmacy systems have added new progress, flotation recovery has improved markedly and has a good performance.According to more than 40 selected gold plant, flotation process indicators survey results show that sulphide flotation recoveries of 90%, a few up to 95% to 97%; oxide ore recovery was about 75%; individual reaches 80% ~ 85%.
