Breakthrough Solutions for Seafloor Mineral Extraction and Processing in deep water environment

Objectives of the commitment

Scientific explorations from the past decades have identified several types of seafloor mineral deposits including Seafloor Massive Sulphides (SMS). In Europe, Azores and Wallis and Futuna are shown to have the potential to contain SMS ores.
To enable commercial deep sea mining socially and environmentally acceptable, technologically achievable and economically viable methods need to be developed. The key innovation in this project is the generic design and in-situ demonstration activities of a cost-efficient and environmentally-acceptable deep sea mining pilot system. This project is complementary with ALBATROSS deep-sea exploration project led by Eramet.
Technology developed in this project will also reinforce Europe’s ambitions to be active in exploration areas outside Europe, thus increasing access to Raw Materials via new mining solutions and decreasing EU dependency on resource imports.

Description of the activities

SeaFlores activities will consist of three different phases:
• Phase 1: Definition of mineral processing route and Feasibility study (FS) of the deep sea mining pilot,
• Phase 2: Pilot Plant detailed design, manufacturing and deployment on the basis of the FS results,
• Phase 3: Offshore demonstration activities in-situ.
It must be pointed out that Phase 1 can be covered by upcoming Horizon 2020 topic “SC5-11-2014/2015: New solutions for sustainable production of Raw Materials, item c) Deep mining on continent and in sea-bed” where the emphasis is on developing new highly-automated technological sustainable solutions for deep mining in the sea bed in-situ and proving the concept and feasibility at the level of TRL 5-6. Activities described hereafter corresponds to this first phase (only).
The process designed to pre-concentrate the Copper / Zinc sulphides shall consider the variability of the ore. Depending on the mineral composition, the process shall be robust enough to remain stable through the changes or be stabilized up front by premixing ore feed. The initial data required in process design can be most reliably obtained from a pilot study. GTK's pilot plant includes a versatile selection of equipment for all unit processes. As each aspect of beneficiation is optimized, it is incorporated into an efficient overall process. Campaign results at pilot scale are typically sufficient to give an accurate idea of the concentration process yield and economic performance at full scale.
Complex sulphide ores contain more than one single valuable metal sulphide mineral each to be separated into its own individual concentrate. Generally, the ore is ground in two stages after which the ground pulp is subjected to conditioning followed by individual flotation stages to produce different concentrates that are then dewatered to optimum transport moisture. Outotec will provide the consortium with complete mineral processing solutions as Outotec has the expertise and capability for designing, supplying, and constructing mineral processing plant.
In order to achieve a viable, environmentally sound and cost-efficient technological solution, a FS will be performed to better define and optimize the mining pilot layout, topsides and associated subsea systems and methods including but not limited to:
• Vertical mining method,
• Free-flying mining method,
• Seabed based crushing and regulation unit,
• Riser and lifting method,
• Equipment launch and recovery method on surface,
• Ore Transhipment method from the mining ship to the ore carrier,
• The environmental impact assessment using “swarm” of Autonomous Underwater Vehicles (AUVs) for the real-time collection and synthesis of all data recovered during mining at sea.
The objective is to compare various design options, evaluate each of them against a number of technical, ecological and economic criteria and, finally, select the most feasible pilot layout.
Environmental management plan that includes preliminary Environmental Impact Assessment (EIA) and risk management strategy will be delivered by Heriot-Watt.The aim will be to propose guidelines for the realization of the environmental baseline and the Environmental Impact Assessment and to compare them to the existing international regulations including the United Nations Convention on the Law of the Sea (UNCLOS), and relevant institutions such as the International Seabed Authority (ISA).

Description of the expected impacts

Significantly improve Europe’s and also global marine resource base by unlocking deeper deposits in the EU, global sea-bed deposits using tested and evaluated innovative technologies. One of the pillars of the EU raw materials policy is to increase the attention to raw materials sources in Europe. A marine mining pilot-project would be a substantial contribution to ensuring a coherent approach to Horizon 2020 Blue Growth.

Create numerous new jobs in mining and equipment manufacturing industries in many regions of the EU, including remote and coastal areas. Many countries do not have economic deposits of base and precious metals on land. Mining and processing SMS deposits would provide these countries with a degree of self-sufficiency, lessening the need to import supplies of metals.

Push Europe to the forefront in the areas of extraction concepts, technologies and related services. Participation of major European mining players and several European technology providers ensures the efficient use of the project results. Therefore a sharing of issues will enable to elaborate a common solution that automatically will be less expensive and time saving for all.

Reduce both the environmental impact of the mine operation and the risks to the population and natural life caused by potential failures. Environmental and social impacts still need to be properly assessed. For some environmental aspects, subsea mining will clearly be less harmful than corresponding land mining (less area disturbed, no overburden, less residues…).

Reduce energy and water consumption by the reduction of the volume of materials to be extracted from the mine. New opportunities will arise to incorporate energy efficient processes in the FS and minimise waste and emission to reduce the risk of polluting incidents.
