With help and encouragement from a dedicated bunch of local Tin enthusiasts I decided to collect the black sands that are deposited in our reservoir tank every year when winter rains wash through the alluvial terrace above our property.
The sands are sorted, stamped, passed over a shaker table and eventually smelted when enough concentrate is available . All processing machinery has been built here in Cornwall in our engineering shop by myself, it's something I am quite proud of and I occasionally sell the odd Cornish Tin ingot to help provide funds to put towards a hobby which can otherwise prove quite expensive .
A view of my Californian type stamps hidden deep in the undergrowth, it runs with four 60 lb heads which have been in regular use for just over four years and work very well.The cassiterite from this area is extremely fine and is possibly one of the reasons that the old men left so much behind, technology not being available to recover such fine material. I use a 400 micron screen on the bowl of the stamps and the primary concentrate settles on the higher levels of the tray below before being taken to the shaker table.
Our home built shaker table works very efficiently with the very fine cassiterite collected from this area.This picture shows the dark band of cassiterite travelling along the top of the table to its collecting tray while the lighter gangue and waste products are washed over the bottom of the table .
Our home produced Tin Smelting DVD was originally produced to add interest to local historical groups that I regularly give mining talks too. It gives a cradle to the grave explanation of the way we work, the machinery I have manufactured to speed up the process, the smelting method used through to the individual casting of the true Cornish tin ingots I produce. Much of the content shows methods that were traditionally used by the old men and passed on to me by the few that are still alive.
The DVD will work on all Windows platforms and most modern DVD players.
Cost of the DVD including post, packing and insurance to all of the UK : £ 15:00
Our small pocket ingots which weigh on average 60 grams are individually hand cast in traditional sand moulds and produced from the same Cornish Tin as our larger ingots, they are attached to a small explanatory card and make a superb unique and affordable gift.
Cost of the ingot including post, package and insurance to a of UK: £25:00
A true Cornish ingot cast from Cassiterite collected and smelted here on site in the Luxulyan Valley as part of my hobby.
They have been individually hand cast to my own pattern and measure approximately 340mm in length . These are the much larger ingots that were cast in 2010.
They are available for sale at a cost of £ 100:00 including postage and insurance to all UK mainland destinations.
I will accept paypal or cheque.
Overseas please ask for a postage quote.
