We love getting questions about #mining, #minerals and #geology! We were recently asked about the #ScotchLake #Quarry in #CapeBreton (aka the #GeorgesRiver Quarry). Here’s our answer:
#nspoli #NovaScotia #NS #cb
This dolomite #quarry operated from 1899-1951 and was owned by the Dominion Iron and Steel Company (acronym: DISCO!). The #mineral dolomite has many uses, including for acid neutralization in the chemical industry, in stream restoration projects and as a soil conditioner.

DISCO made steel with #CapeBreton #coal and #iron from #Newfoundland in #Sydney's #WhitneyPier neighbourhood (named for Henry Melville Whitney, DISCO's president). #Steel is iron and carbon, and the carbon is derived from coal.

DISCO used the #ScotchLake #Quarry #dolomite as flux in its #steel mill. Flux is used in the smelting process to promote fluidity and remove impurities in the form of slag. The quarry was also used for construction #aggregate in the 1960s.

In 1912, the #ScotchLake #Quarry was sending 300 tons of rock a day via rail to #Sydney. It employed 65 men. Hand Drills and dynamite were used to extract the rock.
Merry Christmas!
