Raasay: Ironstone processing works - calcining kilns interior

nobody@ipernity.com (Earthwatcher) — Mon, 15 Jun 2020 18:14:39 +0000

Raasay Ironstone Mine and Processing Works

This is an interior view of the base of the ore calcining kilns. The five vertical cylindrical kiln structures since demolished would have stood above the gaps where the daylight is now shinging through. The original appearance of the kilns can be seen in the link below.

Background
The two adits of Raasay No.1 ironstone Mine were situated about 2.5 km north of East Suisnish pier and worked the Jurassic (Upper Lias) age siderite and chamosite ores from 1914 to 1920. The mine was owned and developed by William Baird & Co. who also built the terraces of houses in the village of Inverarish to house the mine workers, many of whom were German prisoners of war. A tramway and incline connected the mine to the processing works (crusher, calcining kilns, gantries, loading hoppers) at East Suisnish.

A second pair of mine adits (Raasay No.2 Ironstone Mine) just north of Inverarish were also opened up around the same time but never went into proper production due to geological difficulties (faulting).

There was also a small amount of opencast outcrop mining carried out near the No.1 Mine, again around the same time.

The works were dismantled by 1943 but the site is now a scheduled protected monument.

These concrete blocks just above centre originally supported the conveyor gantry from which ore would have been transported from the crusher to be fed into the calcining kilns. Part of the crusher house wall is visible just below the building on the skyline. The gantry and crusher house can be seen in the 1917 photo in the link below.
