In 2018, a "giant sea cannon" appeared in the South China Sea, its spectacular debut attracting global attention. This was not a rumored "superweapon," but a deep-sea mining vessel. It can operate freely at depths of 2,500 meters and can load up to 39,000 tons of minerals in a single operation, having profound significance for the development of my country's mining industry. Remarkably, this giant ship generates a profit of 13 million yuan per month simply through leasing.
> Deep-Sea Mineral Resources
With the arrival of the 21st century, humanity's demand for resources continues to rise. Given the limited nature of land-based mineral resources, more and more countries are turning their attention to the deep sea. The ocean covers 71% of the Earth's surface, and within the 4,000 to 6,000 meter depth range of the seabed, there are abundant deposits of copper, cobalt, nickel, and manganese nodules. Their average grades are 1.00%, 0.22%, 1.3%, and 25.00%, respectively, providing boundless wealth for human mineral development.
> Historical Exploration of Deep-Sea Mining
Starting in the 1970s, deep-sea minerals became a target of many countries. In 1974, the United States claimed to be mining precious metals on the seabed, attracting the attention of countless investors. However, this action was actually a carefully planned hoax. Although the United States and other countries invested heavily, they ultimately failed to achieve practical results due to various reasons and had to abandon their deep-sea mining plans.
> Challenges of Deep-Sea Mining
Currently, the process of seabed mining typically involves a mining vessel arriving at the target area, followed by the deployment of equipment including mining vehicles, auxiliary cutting vehicles, and ore collection vehicles to the seabed. This requires high technological capabilities, including the operation and maintenance of mining equipment, overcoming complex sea conditions, and significant investment. Furthermore, deep-sea mining activities must carefully assess their impact on the ecological environment, as many deep-sea polymetallic sulfide deposits are located near hydrothermal vents, and the ecosystems in these areas are extremely rare and fragile.
