Breakthrough in key technologies of subsea mining and dressing equipment

On November 1, China International Chamber of Commerce Engineering Ship Committee and North Car Marine and Ocean Engineering Development Co., Ltd. (hereinafter referred to as Beichehai Offshore) and Shanghai Chonghe Industrial Co., Ltd. (hereinafter referred to as Chonghe Industrial) first disclosed in Shanghai, China's seabed Breakthroughs were made in the key technologies of mining and dressing equipment.

It is reported that this technical equipment can cover more than 90% of the domestic and international mining resources of coastal mineral resources. In order to promote the dream of China's marine equipment, we will make positive contributions to the exploration and utilization of seabed mineral resources. At present, the equipment ship technology has been put into production. It is expected that the first complete ship equipment will be officially completed and put into production in December 2014.

The national tin mining company from Indonesia signed a contract at the meeting to become the first international project buyer and operation and maintenance partner of this technology and ship equipment. In addition, Hainan Development Holdings Co., Ltd. signed a joint development agreement with the above-mentioned design and development unit on the day of the event. According to the China International Chamber of Commerce, the successful cooperation between China and India in this event and the deep cooperation in mining and equipment maintenance in the seabed will become an important symbol for the innovation of China's marine mining equipment technology export and cooperation model.

It is understood that marine mineral deposits, as an important area for humans to obtain strategic resources, have been highly valued by countries. The research and development of key technologies for ship equipment such as surveying, mining, transportation, etc. has become an important means of obtaining marine mining rights.

Relevant data show that at present, the major mineral resources in the global deep sea include polymetallic nodules, cobalt-rich crusts, hydrothermal sulfides, natural gas hydrates and so on. Among them, the global ocean floor has 70 billion tons of polymetallic nodules with commercial development value. Indonesia (TIMAH), Malaysia, Thailand, Mexico, Mozambique and other countries with rich marine mineral resources are growing in scale; however, due to equipment technology, some island countries have a depth of only 20 meters, and the equipment is backward. The working surface is difficult to accurately position, resulting in low mining efficiency and low recovery rate. The cooperation between Indonesia and China in equipment technology procurement and mining equipment operation and maintenance will be expected to reverse the above difficulties.
