We love getting questions about mining, minerals and geology! We were asked about the historical #Londonderry #iron mines. Here's the story...

Iron mining and smelting began in #NovaScotia in 1825 when iron mines opened at Nictaux Falls, #AnnapolisCounty, and the Annapolis Iron Mining Company built a blast furnace at Clementsport between #AnnapolisRoyal and #Digby.

Iron has also been mined in numerous other locations in #NovaScotia, including East River, Bridgeville and Stellarton (#PictouCounty), Brookfield and Economy Mountain (#ColchesterCounty), Erinville and other places in #GuysboroughCounty...

One of #NovaScotia's oldest mines was the Sibley Mountain Slate Quarry in #ColchesterCounty. From the 1770s to 1860s it provided shingles and flagstones for buildings in #Halifax and England.

Only the early Acadian mines at Joggins, which provided coal for Fort Beausejour and Port Royal, and the French mine at Port Morien, which provided coal for Louisbourg, are known to be older.

The Sibley Mountain quarry was built on land owned by John Olemixon and was commissioned by his close friend, John Wentworth, who became Lieutenant Government of #NovaScotia in 1792.

The terms cement and concrete are often used interchangeably, but cement is actually an ingredient of concrete. Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement.

Cement comprises 10-15% of concrete and is the key ingredient – the glue that holds it together. The cement and water harden and bind the aggregates into a rock-like mass. This hardening process continues for years meaning concrete actually gets stronger as it gets older.

Cement is manufactured by heating a precise mixture of finely ground limestone, clay and sand in a rotating kiln to temperatures reaching 1450ºC. This results in the production of cement clinker, an intermediate product in the manufacture of cement.

Also in 1825, the #Annapolis Iron Mining Co. built a blast furnace at #MooseRiver (#Clementsport) to smelt the magnetic ore recovered from three seams in #Clementsvale (the Miller, Potter and Milbury), as well as to accommodate production from the #Nictaux deposits.
