Gold Refinery Process: From Raw Material to Pure Gold-Mintly
Gold smelting is an essential process in the journey from raw material to pure gold. Smelting is the process of heating and melting the gold concentrate to separate it from other impurities and achieve a higher level of purity. This crucial step plays a significant role in transforming the gold concentrate into a more refined and usable form.

· Alluvial Gold Mining & Processing. Placer gold refers to gold that is formed from rock gold in mountains washed away by rivers and separated from gold and quartz veins. Because this type of gold is as fine as sand, it is called placer gold. Placer gold is easy to mine, but the rock gold mining process is relatively complex and arduous.
