Converting copper ore to copper metal often involves many steps. First, the ore is crushed into small pieces. Then the crushed pieces are mixed with water to form a slurry, a soup-like mixture of crushed ore and water. The slurry is spun around in large vats with steel balls to crush/the ore to an even finer powder.
How many hours a week should Canadians be working? Home to Toronto â the financial capital of Canada - you might think Ontario has the longest work week in Canada. But it turns out Albertans work the hardest, racking up an average of 39 hours per week compared to the average Canadian, who works 36.6 hours per week. Quebecers have the shortest average work week with only 35.4 hours.
While four in 10 workers put in a standard 40-hour workweek, many others toil longer than that, including nearly one in five (18%) who work a grueling 60 hours or more. That translates into 12-hour days from Monday to Friday -- or into shorter weekdays with lots of time spent working on the weekends. Salaried workers, on average, work even more, with a full 25% saying they put in at least 60 hours per week.
