Galena Hill, Mayo mining district, Yukon, Canada : A group of silver-lead-zinc mines clustered on Galena Hill and the adjacent Keno Hill were major producers of silver, lead, zinc and cadmium in the 1940s and 1950s, exploiting the large Galena OXIDATION OF SULFIDE MINERALS.

The Company's wholly owned zinc-copper-lead-silver-gold Caribou Mine is located 50 kilometres west of Bathurst, New Brunswick, Canada. The operations consists of an underground mine with significant underground development, a fully permitted 3,000 tonne per day mill, a sulphide flotation recovery plant, metallurgical and geochemical
Worldwide Supply of and Demand for Lead. Currently, approximately 240 mines in more than 40 countries produce lead. World mine production was estimated to be 4.1 million metric tons in 2010, and the leading producers were China, Australia, the United States, and Peru, in descending order of output.
Formacin y ambiente Los yacimientos de galena casi siempre tienen un origen de tipo magmtico hidrotermal, formndose por consolidacin de los residuos del magma que quedan despus de la formacin de rocas como los granitos y las pegmatitas; en estos casos, el mineral aparece asociado a esfalerita, argentita, cuarzo y fluorita.
Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

Lead concentrations in spotted wolffish (Anarhichas minor) collected from the vicinity of a sphalerite–galena mine and an ore concentration plant in West Greenland have been measured through a period of 2 yr before and 4 yr after mining operations started.Lead levels increased significantly since mining started, and accumulation takes place in liver and kidney, not in muscle tissue.

Galena, or lead sulfide, the world's major source of lead ore, occurs worldwide; and, it is mined in many countries, including the United States, Australia and China. Lead ore comes from underground mining operations, where the lead ore seams are blasted out of the ground and transported to

The first Report on Human Biomonitoring of Environmental Chemicals in Canada was published in August 2010 and included baseline data for 92 environmental chemicals measured in cycle 1 (Health Canada, 2010a). Data for cycle 1 of the CHMS were collected between March 2007 and February 2009 from approximately 5,600 Canadians aged 6 to 79 years at 15 sites across Canada.
Oct 25, 2010Canada's first diamond-mining operation began production in October 1998 at the Ekati mine in Lac de Gras, Northwest Territories, followed by the Diavik mine in 2003. According to Statistics Canada, the mines produced 13.8 million carats, worth $2.8 billion, between 1998 and 2002.

LEAD INDUSTRY PROFILE LEAD PRODUCTION About 60% of lead produced world-wide is derived from ore. Lead ore is mined in many countries around the world, though three quarters of world output comes from only six countries: China, Australia, USA, Peru, Canada and Mexico. Small amounts are mined in several countries in Europe, with the biggest producer
Galena is capable of taking an equally heavy toll on workers and amateur researchers who are exposed to it. Contact with specimens may lead to lead dust exposure, while workers in mines face a high risk of poisoning from contact with the mineral and the deadly dusts released through production.
Lead mining, steamboats and Galena's Golden Years. While you're at the Museum learning about the Driftless Area, check out the stories of Galena's prime when it was actually bigger than Chicago. During the mid-1800s, the rich lead in the area prompted the first major mineral rush in the U.S.
The largest producer of lead materials in the world is Australia followed by the USA, China and Canada. Lead is extracted from ores dug from under-ground mines. Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjunction with other metals such as silver
