Placer Gold Mining Process
The goal of placer/alluvial gold mining is to maximize the recovery of gold and associated heavy minerals from gangue.

Placer gold washing:

This crucial step precedes the separation of placer gold. Its primary objective is to separate gravel, sand, and granular soil while also removing fine mud adhering to the gravel and any mixed-in gold ore.

Placer gold Screening:

The main purpose here is to screen the placer gold ore after washing in order to eliminate large pieces of non-gold-bearing gravel and enhance the efficiency of gold recovery.
Gravity separation: Since placer gold exists in a free state and has a noticeable difference in specific gravity compared to sand, using gravity separation is an ideal method for extracting gold from placer ore.

Concentrate processing:

In cases where gold contains various metal minerals or impurities, additional processes such as gravity separation, magnetic separation, flotation, electric separation or their combination can be utilized for mutual isolation. These processes further improve the grade of extracted gold.
