Stage 1. A Macerator processes ore iron, gold, copper, tin, lead, and uranium into 2x crushed ore of the corresponding type. It does not process (as of ) ores for coal, lapis, diamond, redstone, emerald, or nether quartz. Crushed ore can be smelted into ingots (except for uranium).
Gold Mining Process Development – Denver Mineral Engineers
REFRACTORY ORE PROCESSING. The common definition of "refractory" gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.
Siltation of Ore Particles in Leaching Tanks: Causative ...
tonnage of ore that can be processed within a given residence time. Coarse gold particles present in such tanks gravitate to the bottom due to their high drag force and get locked up in the silt material. Coarse gold locked up in silt materials in some gold processing plants are as high as 53 g/t (Konadu et al., 2014).

Merrill–Crowe process Wikipedia
The Merrill–Crowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores. It is an improvement of the MacArthurForrest process, where an additional vacuum is managed to remove air in the solution (invention of Crowe), and zinc dust is used instead of zinc shavings (improvement of Merrill). ...
The Basics of Successful Gold MiningPart 1
Part One – The Fundamentals. "Streambed" consists of all of the rocks, sand, silt, gold, and other sediments that end up in the bottom of a creek or river. Streambed always lies on top of bedrock. A "lode" gold deposit is gold that is still locked up in solid rock, often contained in quartz veins.
