Gold ..................................

Answer 2

The mineral found in alluvial deposits is Gold.

Explanation:

• Alluvial gold deposits are found at the lower surface of streams, riverbeds, or creaks.
• These deposits are formed in regions where rivers or streams are flowing.
• The erosion of flowing water erodes the top surface of soil leaving behind particles that resist the erosion by gravity and settles at the bottom.
• These particles are mostly minerals like gold, tin, platinum, precious gem stones etc and are extracted through mining.
• Alluvial gold can be present as gold dust, nuggets, pellets, or flakes.
• It is found mixed with other mineral deposits and is extracted and then separated through physical and gravity separation.
