Mining of rare element deposits – comparison land with ocean
Detta är ett förslag på examensarbete för kandidat- eller masternivå vid Institutionen för marina vetenskaper. Examensarbeten vid Institutionen för marina vetenskaper görs självständigt och bedöms individuellt.
Subject: Marine geology
Level: Bachelor
Supervisor: Prof. Laurenz Thomsen, Sedimentology
Project background
Marine mineral resources (i.e., manganese nodules, ferromanganese crusts, and seafloor massive sulfide deposits, elevated concentrations in dump sites) can contain significant amounts of metals, which could, in the future, serve as raw materials to produce construction materials, electronic devices like computers and smartphones, renewable energy technology, and batteries.
Several trends like population growth, industrialization, digitization, and the intended large-scale transition to a low- carbon economy have caused the global demand for metals to increase, evoking fears of future supply shortages. Moreover, several studies have pointed out that deep-sea mining may be preferable to conventional terrestrial mining, as it would neither require the removal of vegetation and overburden nor the relocation of local communities.
Project description
The aim of the bachelor project is to gather data on expected metal concentrations from Deep Sea Mining, mining in the Gulf of Botnia, mining of dumpsites (eg off Gothenburg) or other polluted sites in Swedish waters and compare that with mining in Africa. For Deep Sea Mining and Mining in Africa there are good review papers.
The main work is to gather data for Sweden for comparison on amount, potential, environmental impact, social relevance.
