Ironstone mining in Rosedale

The Ironstone mining in Rosedale, was a major mining concern, in Rosedale, North Yorkshire, England. It flourished in the 19th century and ceased in the early 20th, though smaller scale iron workings were in use through the Middle Ages. The ironstone from Rosedale was typically rated at a higher iron ore concentration in the rock than other mines in the Cleveland and North Yorkshire area.
The first exports from the dale were by horse and cart, but by 1861, the standard gauge Rosedale Railway was built, across the moors to the north to connect the mines with the smelters on Teesside, Tyneside or in County Durham. As the industrialisation of the dale increased, many people moved in to get jobs in the mines, changing the dale from one predominantly dedicated to agriculture, to one geared up to mining. This rush led the local population to refer to the new mining venture as the "Yorkshire Klondyke".
The mines closed down from the 1880s onwards, and all mining activity had ceased by 1929, which led to the closure of the railway.
History.
The valley and moorland at Rosedale, some north west of Pickering, was known to have been worked for iron for hundreds of years (at least 600 years before the 19th century ironstone mining boom); in 1209, Robert de Stuteville granted the use of his meadow in Rosedale to the nuns of Rosedale Abbey. However, the grant stipulated that the forge remain in his ownership. Stone from the quarries on the east side of Rosedale were used in the repair of roads in 1851. This led to an appraisal of the stone and it was found to have a higher concentration of iron ore within the stone than that of the main Cleveland Seam (worked around Eston, Brotton etc), typically 45-50% over 30-35%. This led to the ironstone being known as "Magnetic", and the mines at Rosedale were sometimes referred to as the "Magnetic Mines".
The discovery of thick seams of ironstone outcropping near the surface in Rosedale, caused a large increase in the population. In 1851, 548 people lived in Rosedale Abbey, which by 1871, had increased to 2,839. This in turn, developed the village of Rosedale Abbey beyond what it had before; more schools, chapels, and shops, even a resident police officer. This upsurge in employment, and the influx of people from outside the dale to work in the ironstone industry, led to it being called the "Yorkshire Klondyke", and locally, it is still referred to that in the modern era. In 1856, the Rosedale Mining Company started operations at the Hollins and Low Works drift mines on the west side of the dale, and had expanded their operation into the east side of the valley (Rosedale East) by 1860, and changed their name to the Rosedale & Ferryhill Iron Company. Although the ore needed roasting to drive off the carbonate, the seam on the east side was thick.
The kilns at Rosedale West (Bank Top) were built in 1856 and took 18 months to construct. The kilns allowed the mined and quarries ore to be roasted (calcined) with coal which drove off the impurities and increased the percentage of iron and thus, made it cheaper to be transported in bulk via the railway. This was partly due to the nature of how the railway was built. Instead of purchasing the land outright, the landowners were granted wayleaves, which meant they were entitled to a payment for every tonne of mineral carried, so the ore was roasted to prevent waste material being carried and levied upon. The kilns at Rosedale East were located at Low Baring. 
The railway was opened up in 1861 via the steep incline at Ingleby Greenhow, which connected the line with the North Eastern Railway line at Junction railway station. The railway was extended into East Rosedale in 1865. Prior to the arrival of the railway, ore was taken to Pickering by horse and cart and was railed via and to the Derwent Ironworks in Consett. The use of horse and cart to transport ore (nearly in 1860–1861), was the last large-scale use of this type of transport in the area, though some smaller concerns did still use horse transport. Before the railway's arrival, production was limited to between and per year, but in January 1861, a tramway was built connecting Hollins Farm mine to Bank Top (Rosedale West), that enabled production to vastly increase its output to over in 1862. Initially, coal mined at Rosedale Head was used to roast the ore, but later, coal from County Durham with a higher calorific value was used.
The Kitchen's and Garbutt's workings, both named after the farms they were discovered on, operated between 1853 and 1880. It is estimated that in their 23-year operating life, they produced of ore. The steep hill from the village of Rosedale Abbey to the site of the kilns at Rosedale West became known as Chimney Bank, due to the presence of the high chimney at the top of the hill. The chimney, which actually vented fumes from the stationary winding house boiler room, was demolished in 1972.
The combined output from the mines reached a peak in 1873, when was shipped down the incline for onward transportation to the ironworks. In the 68 years that the railway was open, it has been estimated that it transported over of ironstone for the smelters on Teesside and the North East. The Rosedale & Ferryhill Iron Company collapsed in 1879 after a slump in the iron market, and the all the mines ceased activity, with 1880 showing no tonnage moved. Some of the mines were re-opened in 1881 under the control of the Carlton Iron Company. In 1885, the Rosedale West mines (Low Works, Lane Head, Hollins Farm) were officially closed, but the kilns were kept open roasting the ore from other mines (Sheriff's Pit). The "Magnetic Mines" workings at Kitchen's and Garbutt's had ceased operations in 1880. A study of employment at Rosedale West found that in 1896, of the 121 people working there, 110 were listed as 'working underground', with 77 in 1899 and 80 in 1900.
Several proposals for light railways into Rosedale were proposed, but none came to fruition. The last one put forward was in 1900, when a line extending from railway station on the Gilling and Pickering line with an aim to get within of the village of Rosedale Abbey.
The mines closed progressively until final use of the kilns at Rosedale East came in 1926. This led to the closure of the railway and the abandonment of the kilns. However, a small reprieve came for the railway as dust from the calcination process (calcine), was exported form the kilns sporadically until 1929. The closure of the industry was partly due to the loss of available ore, but also in part to the General Strike of 1926, where iron prices were very low, so places like Rosedale became unprofitable.
Post-closure.
The various buildings and structures were demolished; the community that had built up around Blakey Junction (where the railway line diverged to Rosedale West and East), had its last house taken down in 1955. The kilns at Rosedale East are now scheduled monuments.
