South Crofty Mine Mill 2: This is the second page of images taken in the Mill area during 1997. I was on my own for most of the time, it was very spooky in there.
The mill was closed during 1985 after the Tin price crashed from £10,000 per ton to £3,300 which amounted to half the production cost at the mine. Carnon Consolidated Ltd who were the owners at the time had to make major changes to survive.
One of the group’s mines Pendarves had to close. Also the South Crofty Mill closed, underground production at Wheal Jane was suspended. But the mill there was kept in operation to treat all the South Crofty ore. By 1988 all South Crofty output was being transported to Wheal Jane in heavy lorries. This arrangement remained in place until 1998 when the mine closed.
The Ball Mill consisted of a large metal cylinder on rollers. The cylinder would have been filled with hundreds of metal balls of several inches diameter. The crushed ore material would be fed into the mill which was rotating. The action of the metal balls on the ore would subsequently release the metal particles.

The rest of the images on this page were taken in the Recovery Plant. The roof here was in a very dangerous state. I am so glad I have this photographic record.
If there is anyone who can help with information on some of the images, please get in contact with me.
