With the major increase in gold mining, heavy machinery is allowing for larger exploitation of deposits of lower grades, including re-mining of abandoned mining areas that had been exploited in the past with less elaborate equipment. Alluvial gold mining, or placer gold mining, can take place on land, resulting in a footprint of bare soil and ...

Primary and secondary processes could leave their chemical imprint in gold particles. Combining both morphological and chemical analysis of alluvial gold we will constrain the genetic and sedimentary evolution of the particles, as a starting point to develop a regional exploration model to discover new deposits. 2.

The alluvial tin ore is often mixed with lots of stones, sand, gravel, soil, and sticky clay; in some ore fields, the tin ore is existing with other minerals like magnetic iron, tungsten, ilmenite, hematite, monazite, and zircon sand, etc. The alluvial tin ore processing method is similar to placer/soil gold processing.

Alluviums are thin deposits, in the form of layers, made of material transported by flowing waters, sediments on the bottom of the riverbed, on the meadow or at the water spill. They are made up of boulder, gravel, sand and mud. If they contain noble metals (gold and silver), they are called golden alluviums.

The deep fill sluice box is mainly used for land washing of placer gold mines. Compared with the shallow filling sluice box, the deep filling sluice box has a larger section depth and a narrower width. The groove depth is usually 0.3～1m, and the width is not less than 1.2 times the groove depth, but its length is longer, generally 20～100m.
