Gold occurs principally as a native metal, i.e., gold itself.Sometimes it is alloyed to a greater or lesser extent with silver, which is called electrum.Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as colour) embedded in rock minerals.
Wilfley tables typically act as rougher tables on gravity gold concentrate ahead final concentration methods (e.g. panning) High value heavy mineral concentrate cleaners. In mining, the vast majority of Wilfley-type tables are installed globally to concentrate (e.g.) tin, tungsten, tantalum, niobium, zircon, rutile, leucoxene, xenotime, monazite
Feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from above. The feed slurry contacts the base plate of the vessel and, due to its rotation, is thrust outward. The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a ...

A gold nugget is a naturally occurring piece of native gold. Watercourses often concentrate nuggets and finer gold in placers.Nuggets are recovered by placer mining, but they are also found in residual deposits where the gold-bearing veins or lodes are weathered.
Borax is a crystal-forming mineral that can be reduced to a powder, in this case for use as a flux. The borax method is a technique of artisanal gold mining, which uses borax as a flux to purify gold concentrates.
Roasted gold ore from Cripple Creek, Colorado. Roasting has driven off the tellurium from the original calaverite, leaving behind vesicular blebs of native gold. Roasting is a process of heating a sulfide ore to a high temperature in the presence of air. It is a step in the processing of certain ores.
