Geochemical Exploration for Gold Through Transported ...

Gold ore under 10 m of cover in the northern portion of the Gap deposit was readily detected by analysis of Au by fire assay and ultra trace aqua regia methods in the -80 mesh fraction of these loam soils. Arsenic anomalies occur over the northern end and over the main ore zone at Gap, where there is 25 to 50 m of alluvial cover.

Gold Extraction & Recovery Processes

29-02-2016 · The alluvial gold mining industry has enormous sampling problems. For example, large boulders, sometimes over one meter in their largest dimension are sometimes found along with tiny particles of free gold. Big trommels are employed to remove the washed oversize, but this stream can transport some gold particles creating losses.
