How to find gold in the sand?

Gold particles separated from sand particles are essentially pure substances obtained from the mixture. According to the different densities of sand and gold, people wash the sand containing gold chips in water to make it rotate. The sand goes gently with the water, and the gold stays at the bottom, which is commonly called gold panning.

After washing a lot of sand, you can get very few gold particles. These small gold particles can be melted and processed into gold nuggets. Gold bars, etc. Therefore, it is not easy to find gold in the sand, and it must pay huge labor. Later, people quoted "panning for gold in the sand" as a metaphor to select the essence from a large number of materials.

The origin of the gold rush

At the beginning of the 19th century, the United States launched the westward movement to expand to the west, and groups of adventurers pushed to the west coast of the Pacific Ocean. After the news of the discovery of gold mines in California was confirmed, it triggered another wave of immigration. People leave their jobs at hand and flock to San Francisco, trying to realize their dream of gold rush.

/kloc-At the beginning of the 9th century, the United States began an unstoppable westward movement, pushing the American frontier from the Mississippi River to the west coast of the Pacific Ocean.

1848, people who went to California discovered a gold mine here, which immediately caused a sensation in the world and quickly formed an unprecedented gold rush, which greatly stimulated the westward movement and the development of the western United States. The gold rush is an important part of the westward movement, just like a bright fragment on a magnificent picture.

American westward movement

The gold rush in California is closely related to the westward movement in American history.

It directly originated from a series of activities of people in the westward movement: First, the gold mine discovered in California in 1848 is located in the Sartre community in New Irvine, which is located at the intersection of the Sacramento River and the American River. It is one of the two largest early colonies of American immigrants on the Pacific coast, which was built by American immigrant Sartre in 1848;

Secondly, Marshall, the discoverer of the gold mine, was an American immigrant who conquered the Pacific coast. He was born in capitalist New Jersey. 1844, he embarked on a journey to the west, moved from Missouri to Oregon, and settled in Sartre community the following year.

Once again, a gold mine was discovered in the diversion ditch of the waterwheel of Marshall and Sartre sawmills. When the gold rush broke out, the wood processing here immediately solved the urgent needs of gold miners' production and life.
