If the committee rejects the Pensana proposal it would need to be as a result of showing the UK could obtain magnets sustainable from another source. So far that does not exist.
Tony, there is no realistic hope of the Uk being able to obtain magnets from Pensana. First Pensana does not have a mine or access to raw material. Second do you have any idea of what it takes to build a plant to mass produce magnets? Not to mention the R & D and technology involved? I am sorry but it will never happen. Just to give you a tiny taste of what is involved in magnet production read this from Toyota:
Development background
It is important that magnets used in automotive motors and other applications have high coercivity (the ability to maintain magnetisation) even at high temperatures. For this reason, approximately 30 per cent of the elements used in magnets are rare earths.
When powerful neodymium magnets are used at high temperatures, such as for automotive applications, terbium and dysprosium are generally added to increase high-temperature coercivity. However, terbium and dysprosium are rare and expensive metals found in locations with high geopolitical risks. Because of this, considerable efforts have been made to develop magnets that do not use these metals, and positive results have been achieved.
Production volumes of neodymium are relatively high among rare earths, but there are concerns that shortages will develop as electrified vehicles, including hybrid electric and battery electric vehicles, become increasingly popular in the future. Despite this, little effort has been made to address neodymium use.
To overcome these issues, Toyota successfully undertook development of technologies that can eliminate the use of terbium and dysprosium and reduce the amount of neodymium used. Through substitution of neodymium with lanthanum and cerium, which are abundant and low-cost rare earths, high heat resistance can be maintained and loss of coercivity minimised.
Use of rare earth in neodymium magnets
The new neodymium-reduced, heat-resistant magnet is able to maintain coercivity even at high temperatures because of the combination of three new technologies: –
Magnet grain refinement
Two-layered, high-performance grain surface
A specific alloying ratio of lanthanum and cerium
Mine to magnet is a lovely sounding cliche, but that is all it is, a cliche. Pensana needs to focus it's extremely limited resources on becoming a miner and forget this nonsensical dream of becoming a major manufacturer. It damages the credibility of management and erodes shareholder wealth.
