Sulphides are chemical compounds of sulphur and metal. Massive sulphides, such as iron sulphide (pyrite), copper sulphide (chalcopyrite) and zinc sulphide (sphalerite) sometimes occur, as do sulphides of other metals such as gold and silver. The relatively high content of precious metals in particular makes these massive sulphides interesting for marine mining. Source: www.worldoceanreview.com<\/p>\n

When the first \u2018black smokers\u2019 were found in 1979, nobody even considered their raw materials. Yet, when massive sulphide deposits with a partially very high concentration of valuable metals such as copper, zinc, gold and silver were detected at the edge of these deep-sea sources, interest in them was piqued. As the technical effort and costs of mining these raw materials are very high, doing so was not deemed economical for many years. <\/p>\n
This could now change. The energy transition and the associated decarbonisation will increase future demand for metallic raw materials significantly. Alongside this, raw materials are becoming more and more expensive, making cost-intensive mining economically worthwhile. Mining raw materials on land, such as copper in Chile, cobalt in the Congo and rare earths in China, is also coming under increased scrutiny in terms of environmental impact, working conditions and, not least, geopolitics. All this leads to an increasing interest in marine raw material deposits.<\/p>\n
However, it has been forbidden for a country to explore and mine them outside its own territorial waters since the adoption of the United Nations Convention on the Law of the Sea (UNCLOS) in 1982. Since then, the deep seabed outside national territories and the mineral resources within have been considered the \u201ccommon heritage of mankind\u201d. Exploration and mining may only take place here once prior authorisation has been granted by the International Seabed Authority (ISA). Each country is responsible for its own area.
\nOnce a licence has been granted, however, the area in question must be explored within 15 years. If it is not, the authorisation expires. \u201cThis has now created a certain amount of pressure to carry out explorations,\u201d reports Leonhard Weixler, head of the Diaphragm Wall Equipment division at Bauer Maschinen in the Bavarian town of Schrobenhausen. <\/p>\n
The mechanical engineer had long been interested in deep-sea mining. Then, in 2014, when he met Heiko Felderhoff, Managing Director of the Bremerhaven-based Harren & Partner Group at the meeting at which the Deep Sea Mining Alliance in Hamburg was founded, it quickly became clear that their expertise, and that of their two companies, complemented each other perfectly. After all, suitable ships and civil engineering machinery, alongside the corresponding maritime and technical expertise, are basic prerequisites for deep-sea mining. Both companies are also already experienced in offshore business.<\/p>\n

With this new company, they initially want to provide services in exploring massive sulphides. In view of the approximately 90,000km-long crater rims on the continental plates, in which deposits are found every 10 to 50km or so, only about 200 have been discovered, so exploring them is already quite a task. \u201cWe leave the mining to other people, for now we\u2019re concentrating on the samples,\u201d says Weixler. <\/p>\n On the equipment side, the joint venture is already well positioned. \u201cWe have ships with dynamic positioning, i.e. those that can hold their position without anchoring or mooring,\u201d Felderhoff explains. Furthermore, some additional equipment such as ROVs (Remotely Operated Vehicles) is still needed, and the construction machines still have to be made suitable for deep-sea use. <\/p>\n The massive sulphides at depths of 2,000 to 6,000m will be extracted using the \u2018vertical approach\u2019. \u201cThis is a tried-and-tested method in special deep mining, in which only one \u2018tool\u2019 is used for extracting materials,\u201d Weixler explains. \u201cThe soil doesn\u2019t then have to be crushed for transport to the ship.\u201d The raw material is extracted like this with minimal environmental impact, he adds. \u201cWe\u2019re currently holding detailed talks with Jacobs University Bremen on how this is achieved as sustainably as possible,\u201d Felderhoff emphasises.<\/p>\n The joint venture\u2019s potential client\u00e8le includes licensees \u2013 usually countries or mining groups. \u201cAbout 10 to 15 samples measuring about seven metres and weighing about 100 tonnes are then taken from the licensed area on their behalf,\u201d Weixler tells us. \u201cThe material is then analysed and the data given to the client so that they have a clear picture of the quality and composition.\u201d An initial contract with a client for drilling in their national territory is currently being negotiated. \u201cWe aim to sign the contract in May,\u201d says Felderhoff. \u201cWe then want to start using the technology from Bremen in late 2022.\u201d (cb)<\/em><\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.logistics-pilot.com\/wp-content\/uploads\/2021\/05\/grafik_800px.jpg” title_text=”grafik_800px” _builder_version=”4.15.1″ global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.15.1″ text_font=”roboto-regular||||||||” text_text_color=”#003a7c” global_colors_info=”{}” theme_builder_area=”post_content”]\u201cSmokers\u201d are formed in magmatically active ocean regions. Water seeps through cracks in the seabed several thousand metres deep underground. Near magma chambers, it heats up to around 400\u00b0C and dissolves minerals from the rock. Its low density causes it to rise and shoot back into the sea via the smokers. The reaction with the cold seawater forms mineral particles that are deposited in the chimneys of the smokers or on the seabed.
