What is the Alluvial Gold Mining Method? Mining-pedia

Let's dive right in! Alluvial gold is a kind of gold ore produced in the bottom or low-lying areas of rivers, mixed with stone sand that can be washed out. Artificial gold panning is a common gold mining method for alluvial gold, but with the development of mineral processing technology, the alluvial gold mining method has become diversifiedThese gold adsorbents exhibit a high gold extraction capacity at a gold concentration from 500 ppm-3000 ppm 12,13,14,15,16,17,18,19,20,21,22, but this capacity decreases to less than 250 mg/g at aHighly efficient and selective extraction of gold by reduced
