scme system hydraulic gold ore



What is Hydraulic Mining

First developed as a modern technique in 1853 hydraulic mining was implemented as a means of sifting through rocks and sediment to find traces of gold ore The usual application was to construct paths and canals that would free water from the higher mountain ranges and store the collected water in ponds located several hundred feet above the terrain that was to be mined.

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution mineral processing hydrometallurgical and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing resulting
