Canada.
—The principal phosphatic rock in Canada is apatite, which occurs in workable quantity in two main districts—one in the Province of Ontario, the other in the Province of Quebec. These deposits, which were worked mainly by quarrying, are now practically abandoned. Rock phosphate occurs in a thin bed near Banff, Alberta, but is not used.
South America.
—In Aruba and Curacao, islands of the Dutch West Indies, off the coast of Venezuela, are deposits of phosphate rock, from which a small quantity is mined and shipped to Europe. It is reported that the output in 1914 was about 100,000 tons, averaging 85 to 90 per cent. of calcium phosphate.
In Peru, in the Department of Ica, is a deposit of nodular lime phosphate, which is not used because of a local preference for guano.
A large, rich deposit of phosphate is reported in Chile, about 300 miles north of Valparaiso, but has not been developed as yet.
Phosphate deposits occur on the Island of Salut and on the Connetables, close to the coast of French Guiana. The rock is exported.
Europe.
—The high-grade phosphate deposits of Belgium are exhausted, only low-grade deposits remaining. The rock is found in layers and pockets, and carries between 25 and 65 per cent. of bone phosphate. The production from 1911 to 1913 averaged more than 200,000 tons annually.
