Chinese ancient currency is relatively rare. Like shells and stones of ancient times, the oldest are some of the food they beat. Then there are coins of various shapes made of copper. Next is our world fixed currency gold and silver. There is also the paper money that we made in Song Dynasty
China is a country with 5000 years of cultural history. So our country has the most exotic currencies. In the Yellow River Valley in ancient times, we didn't have money, we all hunted together, and then we went back to our houses to share our prey. So money at that time was food, that is, the food of other animals was exchanged for the food of other animals. With the increase of the number of people living in groups, our currency has been replaced with shells and more beautiful stones, which is a manifestation of the progress of life. When people know how to dress up, they will wear shells in strings around their necks. For example, the first Chinese dragon unearthed in Puyang City, Henan Province, is a dragon shaped pattern with shells{ RRRRR}with the development of time, the initial country was formed, and the country unified its currency. Our currency became a copper currency. There are many shapes of this kind of currency, such as round, concentric circle, square, knife and so on. After that, gold will appear in our vision. Yuanbao appeared in our country, which is the unique currency of our country. In the Song Dynasty, our country was highly developed, and the circulation of money was very large. In some places, there will be banknotes, which are made by many businesses together. This is a pioneering work of our country, and it has also influenced the world. Our country is still using paper money as our common currency. The history of currency is a development history of our country. The development of currency represents the development degree of our country. All kinds of exotic currencies represent the brilliant development history of our country

copper ore beneficiation process:
the flotation of disseminated copper ore generally adopts a relatively simple process. After one-stage grinding, the fineness of - 200 mesh accounts for about 50% ~ 70%, one roughing, two to three cleaning and one to two scavenging. If the disseminated particle size of copper mineral is relatively fine, the stage grinding process can be considered. Most of the concentrators dealing with bornite adopt the stage grinding and separation process of regrinding and cleaning of coarse concentrate, which is essentially a mixed preferential flotation process. High grade copper concentrate and sulfur concentrate are obtained by first roughing, roughing and scavenging, then regrinding and cleaning. Coarse grinding fineness - 200 mesh accounts for about 45% ~ 50%, regrinding fineness - 200 mesh accounts for about 90% ~ 95%
because chalrite and pyrite are closely associated in dense copper ore, pyrite is often activated by secondary copper minerals, and pyrite content is high, which is difficult to inhibit and separate. In the separation process, copper concentrate and sulfur concentrate should be obtained simultaneously. Usually, the tailings after copper concentration is sulfur concentrate. If the gangue content in ore is more than 20% ~ 25%, it needs to be separated again to get sulfur concentrate. Two stage grinding or stage grinding is often used to treat dense copper ore, and the grinding fineness is required to be fine. The dosage of xanthate is more than 100g / (t raw ore) and lime is more than 8 ~ 10kg (t raw ore).
