Gold grinding process. Grinding also known as milling, pulverising or comminution, is the process of reducing gold materials to powder or very fine particle size. Gold grinding process is different from crushing or granulation process reducing the raw material to a rock, pebble or grain size.gold grinding is an integral part of gold mining process.
Gold pans and sluice boxes were necessary tools for the placer miner, but they were of little use in the large mines.

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.
