hi Jim,
I understood that the dressing plant in Hard Level Gill was designed to take Barytes, from these tips!
Not fluorspar, which in any case is pretty low I this orefield!
Regards,
John

Hi John,

Thanks for that detail, I mainly used the commentary from Richardson and Lamb who had investigated the Moor Intake site in Arkengarthdale who suggested the main product being processed there was fluorspar. They did say both fluorspar and barytes were present on the tips in the area in sufficient quantity, the site didn't bother with the barytes. Being rather lazy I just assumed Hard Level Gill would be after the same product.

Would you have some further references I could use to indicate Swaledale Mines Ltd were after both over their various sites. Was the same type plant equally capable of processing both minerals?

Hi Jim, you will find full analyses of the dumps, initially in Dunham & Dines, Barium Minerals in England & Wales, p74, where you will see the highest fluorspar content is only 19% at Sir Franccis dumps,
Dunham revisited this in Geology of the Northern Pennine orefield, volume 2, pages 98-99.
Where you will find detailed analysis of nearly all of the tips in the swaledale/Arkengarthdale area.
Hopefully this should be of assistance to you.

Hi John,

Many thanks, I've also read the addendum in BM 104 which again refers to the Old Gang/Hard Level Gill site suggesting it was using a modified process in the Bedford to glean the heavier barytes at that site.

I'll amend the site notes etc when I get a moment.

Jim
