Placer small-scale gold mining processes. For the material extraction, the topsoil over the placer deposits (ore) is removed and ore is mined using backhoes and dump trucks (). Next, the extracted ore is processed to obtain slurry by mixing water into the placer deposits to liberate gold from other minerals in the ore processing (). Once the gold is liberated, it is then concentrated …
