Mining in Newfoundland and Labrador

Mining has played an important if sporadic role in the economic, social, and cultural history of Newfoundland and Labrador. While Joseph Jukes noted many of the island's mineralogical and geological features in reports of his explorations during the 1830's and 1840's, the first systematic attempt to map out the island's mineral possibilities was Alexander Murray's Geological Survey.

Coagulants and flocculants fact sheet

Gypsum (calcium sulphate), the most commonly used coagulant, has a very low solubility (approximately 250 g / 1,000 L of water) and this is one of the reasons why it is relatively slow to act in most situations (i.e. days rather than hours). Because it is relatively cheap, and it is considered nontoxic, over- -dosing of basins is common.
