Deep-Sea mining is the term applied to processes and technologies designed to collect mineral-rich resources, such as polymetallic nodules, from the deep seafloor. These resources are potential sources of important metals like manganese, cobalt, copper, nickel and rare earth elements, which are soon to be needed in massive quantities in order to build renewables-powered economies as a key component in the fight against global warming.
Lally LLC has been studying the working environments for deep-sea mining, nodule collection, and see the primary potential problems as;
- Physical seabed degradation and resulting impacts to benthos and benthic habitat.
- Contaminant release, including foremost metals.
- Water quality impacts, including elevated total suspended solids (TSS) and lowered dissolved oxygen, primarily at the point of nodule collection (near-field) and processing discharge in upper water column.
- Energy consumption
Lally has over 3 decades of experience solving similar problems in the field of environmental dredging, and sediment processing, directly applicable to these challenges. We are in development phases of solutions, both technologies and approaches, that aim to reduce environmental impacts and energy consumption, by an order of magnitude. while yielding production rates enabling business case viability.
