Mining rights royalties. According to industry insiders, this series of bills may put many Chilean copper producers in trouble. Copper has the characteristics of good electrical and thermal conductivity, resistance to magnetization, corrosion resistance, and easy processing. After the alloy is formed, it also has other properties such as shape memory, superelasticity, and shock absorption.

Brass is an alloy composed of copper and zinc, white copper is an alloy of copper and nickel, and bronze is an alloy of copper with elements other than zinc and nickel, mainly including tin bronze, aluminum bronze, etc. Red copper (also known as red copper) is copper with a high copper content, and the total content of other impurities is less than 1%, which is industrial pure copper. Made of pure copper or copper alloys in various shapes, including rods, wires, plates, strips, strips, tubes, foils, etc. Copper materials are processed by rolling, extrusion, drawing and other methods. The plates and strips in copper materials are hot-rolled and cold-rolled; while aluminum strips and foils are cold-rolled. Pipes and rods are divided into extruded products and drawn products; all wires are drawn. Since the beginning of this year, global copper prices have skyrocketed. At the end of April, London copper futures prices exceeded $10,000 per ton, a 10-year high. Bank of America even shouted that if the expected increase in the supply of secondary materials (non-transparent market) cannot be realized, copper may be exhausted within three years, and the copper price is expected to reach US$20,000/ton by 2025. Market sentiment on the surge in copper prices is polarizing. The industry and traders are not optimistic, but investment banks are more active. Since China is a copper-poor country, the main profits of domestic enterprises come from processing fees, and they rarely enjoy the dividends brought by rising copper prices.

Since the beginning of this year, copper prices have hit record highs, forcing many real industries to transfer costs, especially the semiconductor industry. This year, shortages in the semiconductor market have increased, and rising copper prices are one of the important factors. The latest report released by Goldman Sachs shows that lower copper prices will lead to the risk of inventory depletion in the short term. There are several reasons for the rise in copper prices. One is reduced supply. In 2021, global refined copper production capacity is expected to grow by about 3.9%, but the growth rate of refined copper production in 2022 is significantly lower than expected, only about 1%. The scrap copper supply is about one-third of the copper supply, and the annual copper production is about 30 million tons. As copper prices rise, the market attempts to fill the gap between copper supply and demand and increase the supply of scrap copper.
