Nickel started from 50,000 yuan and soared to $0.01.000 per ton. It has doubled in one day and tripled in two days, and the leverage on futures is about 10 times.

Nickel is a hard, ductile and ferromagnetic metal with high polishing and corrosion resistance. Nickel belongs to the iron-loving element. The inner core is mainly composed of iron and nickel. In the crust, ferromagnesian rocks contain more nickel than silicoaluminous rocks. For example, the nickel content of peridotite is 1000 times that of granite, and that of gabbro is 80 times that of granite.
