About the Partnership

This project is one of a number that are in competition for funding from the NERC Great Western Four+ Doctoral Training Partnership (GW4+ DTP).  The GW4+ DTP consists of the Great Western Four alliance of the University of Bath, University of Bristol, Cardiff University and the University of Exeter plus five Research Organisation partners:  British Antarctic Survey, British Geological Survey, Centre for Ecology and Hydrology,  the Natural History Museum and Plymouth Marine Laboratory.  The partnership aims to provide a broad training in earth and environmental sciences, designed to train tomorrow’s leaders in earth and environmental science. For further details about the programme please see http://nercgw4plus.ac.uk/

For eligible successful applicants, the studentships comprises:

• An stipend for 3.5 years (currently £19,237 p.a. for 2024/25) in line with UK Research and Innovation rates
• Payment of university tuition fees;
• A research budget of £11,000 for an international conference, lab, field and research expenses;
• A training budget of £1,000 for specialist training courses and expenses.

Project Aims and Methods

Acid mine drainage (AMD) is amongst the most problematic issues currently facing the mining industry and yet also poses a significant opportunity for the recovery of green technology metals which are reliant upon to tackle the Climate Emergency. A fundamental issue, however, holding back this opportunity is the fact that AMD contains a wide variety of metals which readily precipitate to form a mixed phase (and often environmentally toxic) ochre product which is difficult to subsequently treat to extract target metals. This PhD project will explore new horizons in the geochemical, electrochemical and/or hydrometallurgy manipulation of this step – to selectively recover key target metals. The candidate will be hosted at the Camborne School of Mines, University of Exeter, benefiting from state-of-the-art analytical facilities and local field sites, but also from collaborations with the University of Bristol (project design and unique analytical capability) and the Coal Authority (site access, project design and industrial synergy).  

Project partners

The Coal Authority will provide in-kind support which will include attendance at regular attendance at regular project steering meetings, sharing existing water quality data held by the Environment Agency and the Coal Authority, technical support for co-development of the project to ensure maximum alignment with Coal Authority and Environment Agency strategic aims and for new policy development. Financial support for a 3 month placement at the Wheal Jane water treatment facility for the PhD student to conduct on-site upscaled experiments to support the aims of their project.  

Training

The DTP offers funding to undertake specialist training relating to the student’s specialist area of research. 

Eligibility

NERC GW4+ DTP studentships are open to UK and Irish nationals who, if successful in their applications, will receive a full studentship including payment of university tuition fees at the home fees rate.

A limited number of full studentships are also available to international students which are defined as EU (excluding Irish nationals), EEA, Swiss and all other non-UK nationals.  For further details please see the NERC GW4+ website.

Those not meeting the nationality and residency requirements to be treated as a ‘home’ student may apply for a limited number of full studentships for international students. Although international students are usually charged a higher tuition fee rate than ‘home’ students, those international students offered a NERC GW4+ Doctoral Training Partnership full studentship starting in 2025 will only be charged the ‘home’ tuition fee rate (which will be covered by the studentship). 

International applicants need to be aware that you will have to cover the cost of your student visa, healthcare surcharge and other costs of moving to the UK to do a PhD. More information on this is available from the universities you are applying to (contact details are provided in the project description that you are interested in.

The conditions for eligibility of home fees status are complex and you will need to seek advice if you have moved to or from the UK (or Republic of Ireland) within the past 3 years or have applied for settled status under the EU Settlement Scheme.
 

Equality, Diversity and Inclusion

The University of Exeter is committed to promoting and supporting equality, diversity, and inclusion within our working environments and is at the heart of all our activities.  With over 27,000 students and 6,400 staff from 180 different countries we offer a diverse and engaging environment where our diversity is celebrated and valued as a major strength.

Whilst all applicants will be judged on merit alone, we particularly welcome applications from groups currently underrepresented within our postgraduate research student community.  Reasonable adjustments are available for interviews and workspaces.
 

Entry requirements

Applicants should have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK.   Applicants with a Lower Second Class degree will be considered if they also have Master’s degree.  Applicants with a minimum of Upper Second Class degree and significant relevant non-academic experience are encouraged to apply.

All applicants would need to meet our English language requirements by the start of the  project http://www.exeter.ac.uk/postgraduate/apply/english/.
