deposit with maximum percentage of copper in ore

Learning Goals: -What is an ore deposit?

2018-8-7 · Typical mines today have ore grades of only 0.6 percent copper. Since metal concentrations occur at much lower grades, the copper concentrations are measured in parts per million (ppm). If a sample has 1ppm copper, this means that in 1 million lbs of rock, there is 1 lb of copper.

That results from the copper being dissolved, percolating down below the water table and precipitating.

20.1 Metal Deposits – Physical Geology

Looking at copper, for example, we can see that while average rock has around 40 ppm (parts per million) of copper, a grade of around 10,000 ppm or 1% is necessary to make a viable copper deposit. In other words, copper ore has about 250 times as much copper as typical rock.

Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The world’s largest copper ore deposits are found in Chile on the west coast of South America. This is due to the

How much metal does the ore contain? « World Ocean

The metal recovered is described as “refined copper”. Mineral ores, therefore, are made up of a combination of different substances and contain only a certain amount of metal. In most cases copper ores contain between 0.6 and 1 per cent of copper. Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper.
