Gold ore, also referred to as gold deposit, in which the main mineral is natural gold. Among them, the content of gold in the ore is extremely low, with high mining value, and its mineral dressing process is more complicated. Gold mineral dressing, often referred to as gold beneficiation/ gold processing, is to select the trace gold in the gold ore, is also an intricate process Aimed at separating valuable gold from its ore. in order to extract gold, the ore is mined, crushed, washed, and then pre-enriched or separated from the ore to make gold mainly by beneficiation methods. This multi-step process usually begins with crushing and grinding the ore to release the gold particles. The various types of gold ores have different beneficiation methods depending on their nature.

Placer or rock gold mining often involves a variety of mineral dressing processes that transform raw ore into valuable metal. However, the more common beneficiation methods for alluvial or rock gold are the following three: gravity separation, flotation, and cyanidation method.
