Metal concentrations in ore vary greatly from less than 1 percent by weight for most gold deposits to over 60 percent for some iron ore deposits most metallic mineral deposits have ore grades in the range of 1–5 percent by weight. Beneficiation sometimes called milling usually occurs at the mine site.
History. The smelting of gold began sometime around 60003000 BC. According to one source the technique began to be in use in Mesopotamia or Syria. In ancient Greece Heraclitus wrote on the subject. According to de Lecerda and Salomons (1997) mercury was first in use for extraction at about 1000 BC according to Meech and others (1998) mercury was used in obtaining gold until the latter
Therefore the Gold Ore Crushers industry has become the focus of technological innovation and economic development in the world today. The developed countries adopt the "re-industrialization" strategy of Gold Ore Crushers industry and China will regard the Gold Ore Crushers industry as the main direction of "Made in China 2025".

Pure gold is a golden yellow color. Pure gold often referred to as 24 karat gold is too soft to be made into jewelry as it wouldn t hold up to the abuse of daily wear. It would get bent and dented before you know it. Therefore pure gold must be alloyed or mixed with other metals to make it more durable.

1.1.6 Beneficiation Although metallic ores contain elevated levels of metals they generate large quantities of waste. For example the copper content of a good grade copper ore may be only one quarter of one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore the next step in mining is
