Providing Global Mineral Processing Solutions HEMERDON TIN TUNGSTEN PROJECT SCOPE OF WORK Process and engineering design for the tin/tungsten concentrator, project infrastructure, water management and site services was undertaken as the lump sum turn-key construction of the full project by GR Engineering. The concentrator receives ore from open cast mining and utilises crushing, gravity and dense media separation as the primary upgrade route for the production of tungsten and tin concentrates. The primary concentrate is treated by gravity processes (spirals and tabling) followed by flotation and a reduction roasting process to achieve a concentrate which is further upgraded by removal of iron using magnetic separation. The final tin and tungsten concentrates are cleaned using WHIMS before drying and bagging of the final products. Tailing from the processing facility is deposited into a designed life of mine impoundment with water recycled to the concentrator. The equipment for the project was sourced from Europe, South Africa, UK and USA. The multi-disciplined management team from GR Engineering effectively delivered the project construction which commenced in February 2014 and concluded with commissioning and ramp up in late 2015.On schedule and in accordance with budget, GR Engineering backed the design with a performance warranty to Wolf Minerals Ltd. Representing the first project of its type in the UK minerals sector in 25 years, the Hemerdon project showcased GR Engineerings’ credentials in delivering large scale, complex, mineral processing facilities anywhere in the world.

Current Developments in Uk Mining Projects
CURRENT DEVELOPMENTS IN UK MINING PROJECTS C P Broadbent1) and C A Blackmore1) 1)Wardell Armstrong International Ltd, 46 Chancery Lane, London WC2A 1JE, UK 1 Introduction In October 2017 The Mining Technology Division (MTD) of the IOM3 organised a highly successful conference “Current Developments in the UK Mining Industry”. The aims and objectives of the conference was to define the then current state of the UK Mining Industry1. This conference was a great success and, with the exception of a presentation on Wolf Minerals Ltd, Hemerdon Project, gave the definitive status of most major UK Mining Projects. This paper provides an update of many of these projects. Although the last UK deep pit coal mine, Kellingley Colliery, North Yorkshire closed in December 20152 and was capped off in March 2016. The UK still has large reserves of available fossil fuels and many types of industrial minerals and metals are found in the diverse geology of the UK. Presently there are a number of major initiatives active making 2018, despite events at Hemerdon, one of the most active years in recent times for “new” UK mining ventures.

The Drakelands project will be the Hemerdon is the third-largest tungsten and tin resource in the world and the Drakelands Mine project, based there, will provide a secure supply of tungsten and UK’s first new mine for more than valuable export revenue for the UK. The project will create more than 200 jobs and 40 years, and it will use ZEISS’s pump hundreds of millions of pounds into the Plymouth, Devon and UK economies Mineralogic Mining automated over the next decade. Its estimated production of 5,000 tonnes per annum of tungsten concentrate and 1,000 tonnes of tin concentrate will mean the £123 million mineralogy system. Rhiannon mine will contribute around 3% of global tungsten supply. Garth Jones speaks to Dr Benjamin Tordoff, Segment Manager for WHAT HAS beeN THE TImefrAme FOR THIS prOjeCT? Mining and Minerals at ZEISS, about Tungsten was discovered at Hemerdon in 1867 and the deposit was identified as the mine and the technology. being a large tungsten-tin vein complex in 1916, during exploration for metal resources to contribute to the war effort – it was subsequently used by government agencies in both world wars. In 1986, after an extensive drilling programme and public enquiry, Amax Exploration UK and Hemerdon Mining and Smelting UK Ltd obtained planning permission to open the mine as an opencast operation working to a depth of 200m. At that time, increased tungsten production by China brought about a considerable reduction in the commodity price and, as a result, the Hemerdon project was placed into care-and-maintenance.

It is therefore, critical to optimize European tungsten operations and maximise recoveries. The role of enhanced gravity/centrifugal concentrators in recovering tungsten from ultra-fine fractions should form an important part of this aim. Reported herein are the results of investigations to improve efficiency of Wolf Minerals’ Draklends mine, a major European tungsten mine, by recovering saleable material from a magnetic waste stream of a low-intensity magnetic separator using an enhanced gravity concentrator. The mine hosts wolframite and ferberite as the main tungsten bearing mineral species. A Mozley multi-gravity separator (MGS) C-900 was selected as it is suited to exploiting small variations in mineral density to affect a separation. Working with a current manufacturer, a novel scraping blade system was tested.

I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. Signature: …………………………… 1 Acknowledgements: First of all a massive thank you to my research tutors Prof. David Hosken and Dr. Kelly Moyes for introducing me ‘bat world’ and for their continued guidance and support, also to Prof. Patrick Foster for his insight into the mining industry. I am very grateful to Wolf Minerals for providing the funding for this research and would like to thank Jess Easterbrook and Hannah Clarke of the Environmental Team and Michel Hughes for introducing me to the Drakelands site and answering my questions. I really appreciate the cooperation of the landowners who let me climb fences and wander through their fields and to set up detectors (David Cobbold in particular) - without your permission this research would not have been possible. Last but not least, I would like to thank Reece and my family and friends for their support and encouragement and for listening to my bat chat over the past year and a half! 2 An investigation of mining impacts on bats in South-West England Abstract: The extraction of minerals through open-pit mining can result in sudden and extensive land use change, often posing threats to local biodiversity.
