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.
And that means the work week might actually just be the 40 hours it's supposed to be. A report that Gallup released Friday showed the average time worked by full-time employees has ticked up to 46.7 hours a week, or nearly a full extra eight-hour day. Just 40 percent of Americans who work full time say they clock the standard 40 hours a week. Another 50 percent say they work more than that.
