Introduction. Gold has been a valuable and sought-after commodity for centuries, and the allure of finding gold still persists today. One of the most accessible ways to find gold is through placer mining, which involves searching for gold in loose or unconsolidated deposits in streams, rivers, or other bodies of water.

Has various types of gold raw material: alluvial gold/placer gold/sand gold/river gold/ gold tailing, etc. The placer gold mining equipment includes feeding, washing, sieving, rough separation, final concentration, and refining. Because the gold density is much bigger than other minerals, so mainly use gravity separation. Chat Online on WhatsApp.

Placer Gold Mining Methods. The gold deposits grouped together under the name of " placers " comprise sands, gravels, or any loosely coherent or non-coherent alluvial beds containing gold. They have accumulated owing to the action of running water, in the beds of rivers, or on the adjoining inundation plains, or on sea beaches.
