This cyanide method is used to process Nevada's Micron Gold Ores. At the refinery, the dore alloy is re-dissolved in a water solution and purified by electrolytic plating methods. Once purified, the metals are used to create jewelry alloys like 14 Karat gold or sterling silver,
PORTABLE HARD ROCK PROCESSING PLANTS SEMI STATIONARY HARD ROCK PROCESSING PLANTS Hard rock mining is the process of extracting metals and minerals encased in rocks (primary deposit). Hard rock ore can contain metals, minerals such as gold, platinum, silver, iron, copper, manganese, zinc, nickel, tin and lead, zircon, etc.
Gold occurs in mineralised hard rock as µm- to mm-sized grains, either as pure grains, but more often enclosed in other minerals, and as free gold in river sediments. Small-scale gold mining is carried out from pits, shafts or tunnels.

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 Hard rock ores have formed the basis of the majority of commercial gold
Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or sub-surface mining techniques are used. Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of low-grade, oxide deposits.
